Sickle cell anaemia is caused by a mutation in the HBB gene. The normal wild-type βA allele contains an MstII restriction site; in the mutated sickle-cell βS allele this restriction site has been lost. PCR amplification of part of the gene encompassing the mutation site from a normal unaffected individual results in a product of 110bp. Digestion of the PCR product with MstII and subsequent gel electrophoresis results in a single band of 55bp.   How many bands and of what size would you expect to see in individuals who: i) has sickle-cell anaemia (has two βS alleles) ii) carry the disease (sickle cell trait) (has one βS and one βA allele)   a.

In biotechnology, gene cloning is a crucial technique used in many genetic modification experiments. A vector is normally required to perform this process. The vector commonly used to transform a bacterial host cell is known as a plasmid. Below is the general plasmid map of pBR322. Elaborate the functions of ori, Ap and TeR present in pBR322.

Recently, I am designing primers specific for Lactobacillus sp. (partial sequence of the 16s rRNA gene) and can get successful amplification on my conventional PCR. Then I am going to quantify by RT-PCR using SyBr Green Reagent in Step One Plus Instrument. By using the same run condition as the conventional PCR, I face the problem that many of my samples got a bad melting curve. Anyone have the same experience as me or suggestion please let me know. Thanks in advance.

In the following "gene library" cloning experiment Digested genomic DNA AmpR gene TCR gene TCR is tetracycline resistant marker, AmpR is ampicillin resistant marker and BamHI is the unique restriction enzyme on plasmid. A PhD student digests/cuts the plasmids with BamHI restriction enzyme and the genomic DNA with EcoRI restriction enzyme. After performing the cloning experiment and obtaining colonies on a selection plate, the obtained cells will be ..... (Hint: this question is even more challenging; the PhD student was later demoted to an MSc student). a) resistant to ampicillin and tetracycline b) sensitive to tetracycline and ampicillin c) resistant to tetracycline and sensitive to ampicillin d) resistant to ampicillin and sensitive to tetracycline e) sensitive to ampicillin and tetracycline BamHI

Below are several problems frequently faced by researchers when running the PCR. Give one (1) solution to each problem stated. 1. No PCR product 2. Multiple bands appeared after gel electrophoresis (you are amplifying just 1 gene) 3. Bright thick bands at the end of the agarose gel after electrophoresis 4. Bands appeared at the negative control

The gel below shows results for the bitter tasting SNP analysis from a CH306 class from a few years ago. Analyze the results and annotate the gel to indicate the bitter tasting ability and homozygous/heterozygous status of each of the individuals represented on the gel. There are three lanes of markers, and the first non-maker lane on the left of the gel is an uncut control PCR product (i.e. there are a total of 10 individuals on the gel starting in lane 3).
