Trimmomatic v.0.36 –REF was used to trim reads by removing leading bases with Phred33 quality scores < 5, trailing bases with Phred33 quality scores < 3, using a sliding window of 4 bases and removing the 5’ terminal base if the average Phred33 score of the 4 bases was < 15, and completely discard trimmed reads with less than 36 remaining bases. The high quality reads were subsequently mapped to the pig genome Sscrofa build 11.1 using the Star software v.2.5.2a and default parameters while simultaneously adding unique read groups to the files – REF. Gene prediction coordinates (release 11.1.90) were obtained from Ensembl (http://www.ensembl.org) Samtools v.1.3.1 –REF was used to merge bams from the same sample and to convert bam files to sam files before HTSeq -REF was run with the reverse stranded option to calculate the number of reads mapped to each gene. …show more content…
The two breeds were analyzed separately and the samples were divided into a high-low contrast based on their hyperactivity values. Filtering was done to keep only genes that achieved at least one count per million in at least half of the samples, and the data was normalized for differences in the abundance of read counts mapped to genes between samples using the TMM (trimmed mean of M-values) normalization method. Variance in gene expression was estimated using a tagwise dispersion model before differential expression was detected with a likelihood ratio test model. FDR was calculated using the Bejamini-Hochberg procedure –REF, and a FDR < 0.05 was considered
The oligonucleotide antisense matches complementary to the region 107–128 of the human Smad7 mRNA sequence, and its
• Use these data to construct a map of these three genes in two steps.
Comparing the BLASTx and BLASTp search results, allowed me to determine if I chose the correct ORF in the Toolbox which I believe I did as the proteins found in the BLASTp search were the same as the proteins found in the BLASTx search. The E-values for the same protein found by both the BLASTx and BLASTp searches were also the same but only the start and stop positions of the BLASTx and BLASTp alignments were different for the same protein. Overall, I determined the 5’ UTR to be G1-A28 and the ORF to be A29-G1051.
During the 1930’s people were often biased and would use specific ways to gain power. The most common ways people obtained power were by their race, gender, and class. For instance, during the 1930’s a white, rich man had more power and influence than a black, poor woman. Harper Lee’s book, To Kill A Mockingbird, is filled with different examples of how power is acquired. For example, Mayella Ewell is a white, poor woman who accuses a black man of raping her.
A quantitative allelic imbalance assay was developed to determine differences in gene expression from individual BRCA1/2 alleles. Allele-specific assays quantify gene expression specific to the allele being tested. For the BRCA1 gene, two individuals homozygous for the BRCA1-c.4308T/T or BRCA1-c.4308C/C polymorphism were tested. Complementary DNA (cDNA) was created from reverse-transcription polymerase chain reaction (RT-PCR) using RNAs extracted from blood lymphocytes. RT-PCR uses reverse transcriptase to form an RNA/cDNA heteroduplex that is then amplified by normal polymerase chain reaction techniques to produce a large quantity of cDNA. Ratios of the cDNA from the two alleles were mixed for use in real-time PCR (qPCR). qPCR uses fluorescent probes that anneal to the cDNA during PCR. These probes contain a reporter and a quencher; the reporter fluoresces when separated from the quencher, allowing a computer to measure the number of cycles needed for the fluorescence to exceed background levels (cycle threshold or CT). Using the ratios of cDNAs and ∆CT, a linear regression was computed to form an allelic expression standard curve that can be used to evaluate allelic imbalance. These same methods were repeated with BRCA2 with two individuals homozygous for the BRCA2-c.3396A/A or BRCA2-c.3396G/G allele.
The Basic Local Alignment Search Tool (BLAST) was the final portion of this lab report. BLAST is provided courtesy of the National Center for Biotechnology Information (NCBI). After running the five chosen tests, students were given the two 16S rRNA sequences that were associated with their assigned culture. The BLAST results served to confirm or disprove the hypothesis of what the unknown may be. The BLAST program compared the given 16S rRNA sequence to a database of known sequences and searched for similarity. (10) This search tool is capable of comparing nucleotide or protein sequences to find statistical significance between the matches. A perfect match to the unknown sequence is indicated by a
Prejudice is the harm or injury to someone that results or may result from some action or judgement.prejudice happened back then and today, the holocaust is a good example of prejudice action.In the play diary of anne frank; Adofl Hitler tried to create a master race so he killed all the jews; he thought they should not live. So Anne and all the rest of the poeple went into hiding to surviv the killing of th jews, but ended up in a interment camp.
If the lifetime of the polymerase is long enough, both strands can be sequenced multiple times (called ‘‘passes”) in a single polymerase read. Moreover, the polymerase read could be split to multiple reads (called subreads) by recognizing and cutting out the adaptor sequences. The consensus sequence of multiple subreads in a single ZMW yields a circular consensus sequence (CCS) read with higher accuracy. If a target DNA is too long to be sequenced only one time in a polymerase read a CCS read cannot be generated, and only a single subread is output instead. Whereas, the CCS sequences are usually generated by transcript sequencing due to its relatively short length. According, Pacific Biosciences developed an independently protocol, Iso-Seq, for long-read transcriptome sequencing, including library construction, size selection, sequencing data collection, and data processing. Iso-Seq allows direct sequencing of transcripts up to 10 kb without use of a reference
This September will mark the 13 year anniversary of the modern day Pearl Harbor also known as 9/11. In these thirteen years our world has changed immensely. Our government went from being the proponents of democracy to seldom acting like tyrannical warlords. The Patriot Act suspended due process for anyone deemed an “enemy combatant”. Defense contractors were given the biggest contract in American history. As a nation, we went to two different wars and almost destroyed the world’s economy. All of this occurred to ensure our safety as citizens of this once great nation. But are we truly safer from terrorist attacks today than we were in 2001? There was a poll that appeared around the five year anniversary of 9/11 that
Interestingly, among numerous genes examined in rats, ɳ-3 deficiency changed the expression of multiple genes in offspring (Tribole, 86).
A 2013 study at Bellumori et al used medical records from the veterinary clinic at UC Davic for more than 27,000 dogs. The purpose of this study was to compare the incidence of 24 genetic disorders in mixed vs purebred dogs.
Priscilla Long wrote the article "Genome Tome" for The American Scholar in 2005. It appeared in volume 74, issue 3, on pages 28-42. You accessed the article from a library subscription database called ProQuest on January 19, 2006.
Observed frequencies of white and yellow body mutant genotypes scored in this investigation. Expected frequency values were obtained from the Observed Frequency values by (A/n) x (B/n) x 100, where A and B are the observed frequencies of the two alleles associated with a genotype. Χ² was calculated from (o-e)2/e, where o is the observed frequency, and e is the expected frequency.
three specific databases. These organisms have been used as model organisms through multiple clinical researches to inform us about biology. They are ideal organisms due to characteristics such as how roundworms and fruit flies grow to adulthood quickly. In addition, they share principles such as the cell cycle in yeast that is regulated by homologous proteins that are similar in humans; hence they will be able to enlighten us on the genetic profiling in humans. The five most used organisms are yeast, fruit fly, bacteria, mouse, and roundworm. Out of those five most common organisms we used roundworm, yeast, and fruit fly to conduct our analysis. To analyze the organisms we had to use databases specifically for each organism (i.e. wormbase.org, flybase.org, yeastgenome.org). We also used the ApE software to analyze gene sequences whose information was not readying available in the databases. From these databases we were given the information needed to analyze each organism.
The origin of the domesticated dog, Canis lupus familiaris, occurred at least 15,000 years ago, evolving from the Eurasian gray wolves, its closest ancestor. Most dogs today are neither mixed-breed nor purebred, but belong to a classification called village dogs, who are geographically widespread and genetically more diverse. Purebreds are not genetically diverse due to the fact that the all come from a small controlled gene pool (Milliken, 2015). The diversity of the village dog is a significant key to unraveling the history of dogs. A study was performed by Laura Shannon et al. that analyzed the autosomal, mitochondrial and Y chromosome diversity in dogs using a technique called genotyping array. Using the genomic data from 4686 purebred dogs from 161 different breeds and 549 village dogs from 38 countries, they genotyped the dogs on a semicustom Illumina CanineHD array that was made up of 185,805 markers, of which included 582 mitochondrial and 336 Y markers. Using the data that they found along with the already existing mitochondrial and array data available, the largest canine diversity panel was created, thus allowed for an easy and efficient comparison model of the Y, mitochondrial and autosomal loci in analyzing the genetic variation in the dog population. (Shannon et al., 2015). The table below shows the diversity of the village dogs of their mitochondrial and Y haplotype diversity.
