From your knowledge about DNA microarray, answer the following: If the expression microarray experiment was done with a normal sample and a suspected sample, after reading the color pattern resulted from the experiment it was recorded that “gene A22” is expressed in the suspected sample. The gene A22 is clinically linked to colon cancer. Answer the following: What is the expected color of the spot on the microarray which represents this gene? What is your interpretation of the suspected sample; is it a cancer sample or not and explain why?

Transcriptome analysis involves two separate methodologies: gene expression and RNA seq analyses. The 10 items below are a scrambled listing of the steps used in the two procedures. Identify the steps involved in RNA seq from the list below. Use the numbers in the list to refer to each step. Once the steps for RNA seq have been identified, write the steps in the order in which they are performed during the experiment. (1) DNA sequencing (2) Allow for hybridization and wash excess cRNA. (3) Mix labeled cRNA with array chip. (4) PCR amplification (5) Measure fluorescence intensity to determine abundance of transcripts. (6) Add labeled cRNA at each microarray location. (7) Map cDNA sequences to the genome of the organism to determine identity and abundance of transcripts. (8) mRNA isolation from cells (9) Prepare fluorescently labeled cRNA probes (10) cDNA synthesis
When doing the virtual DNA microarray analysis, which color (red, green or yellow) would the spot be if that gene was inappropriately inactivated in the cancer cell? When doing the virtual DNA microarray analysis, which color (red, green or yellow) indicated that the cancer cell had an activated a gene that is not normally as active in the non-cancerous version of the cell?

STEP BY STEP Exaplanation would be appreciated so I can understand for upcomming exam. In humans, the COL1A1 locus codes for a collagen protein found in bone. A recessive COLA1 allele believed to reduce bone density and increase risk of fractures differs from the wild type allele by the presence a GT in the first intron of the gene. This mutation can be easily screened by PCR, using COL1A1-specific primers followed restriction enzyme digest of the product with MscI. The normal allele is denoted as G and the recessive allele as T. A recent study of 894 women found that 570 were GG, 291 were GT and 33 were TT. (Assume for this exercise that these values reflect both male and female values for the sampled population. What are the frequencies of each allele? What are the frequencies of each genotype? c. Is this locus in Hardy-Weinberg equilibrium? Use the table below to evaluate the significance of any deviation from H-W expectations.

Describe the main technique for amplifying a segment of DNA (like the one you suspect is involved in Lee’s cancer) from a complex mixture of genomic DNA. Remember that the entire human genome sequence is known. (Hint: This is a technique that is commonly used by laboratories that do genetic testing and various other applications of molecular biology.)
Microarray hybridization is used mostly in transcript profiling or assaying DNA variation. Although the technology for establishing DNA microarrays was developed only recently, numerous applications have already been developed and their impact on future biomedical research and diagnostic approaches is expected to be profound. Give some examples of the practical use of this technique.
STR markers: are point mutations detectable by DNA sequencing are variations in the number of repeats of very short DNA motifs (2-10 nucleotides) □have high polymorphism are mutations leading to proteins or blood groups that can be differentiated by antigenic testing from a blood sample ☐have low polymorphism no correct answer are changes of a few nucleotides leading to the absence or presence of a site recognized by a restriction enzyme are variations in the number of repeats of medium-sized DNA motifs (10-100 nucleotides) can be located in coding sequences are located exclusively on autosomes
The right-hand column contains descriptions of 5 types of molecular markers. Label each description with the name of the being described. Single-nucleotide polymorphism (SNP) Sequence-tagged site (STS) Microsatellite Amplified restriction fragment length polymorphism (AFLP) Restriction fragment length polymorphism (RFLP) Reset Zoom TABLE 23.1 Common Types of Molecular Markers Marker Description A site in a genome where the distance between two restriction sites varies among different individuals. These sites are identified by restriction enzyme digestion of chromosomal DNA and the use of Southern blotting. Amplified restriction fragment length polymorphism (AFLP) The same as an RFLP except that the site is amplified via PCR instead of isolating the chromosomal DNA. A site in the genome that contains many short sequences that are repeated many times in a row. The total length is usually in the range of 50-200 bp, and the length of a given microsatellite may be polymorphic within a…
The human gene for hemophilia is on the X chromosome. Below is a pedigree from a family afflicted with hemophilia. The man with blackened symbol (III-1) has hemophilia. To help with genetic diagnosis, a probe that detects an RFLP (restriction fragment length polymorphism) on the X chromosome is used. This probe detects either a 7 kb restriction enzyme fragment or 3 kb and 4 kb restriction enzyme fragments. The RFLP pattern for all the members of the pedigree is shown. The recombination distance between the RFLP and the hemophilia locus is 40%. What is the chance that their unborn child (III-7) is affected? 4 kb 3 kb Select one: a. 10% b. 20% C. 40% d. 60% e. 80% f. 90% g. None of these above II II
