You are asked to prepare a karyotype of any species.what type of cell division you will look at to arrange chromosomes in order and how?
A genetic disease is caused by a deletion in part of a gene. The deletion results in one copy of the gene being shorter whereas the other copy is normal length. In the gel below, the DNA sequences of this gene from four individuals have been amplified using PCR (the gel is loaded at the top of the tray). Lane 1 of the gel shows an individual who does not have the disease. Which of the bands represents the disease allele? A B C

If you knew the sequence of a gene in one organism, how could you determine if another organism had a similar gene? A. insert the known gene into a vector and use the vector to insert the known gene into the other organism B. treat the genomes of both organisms with the same restriction enzyme and compare the patterns of the bands produced with gel electrophoresis C. create a hybrid of the two organisms by breeding them and check for mutations D. create labeled DNA probes from the known gene and use them to search the genome of the other organism
A) What are the three main steps involved in PCR? Include temperatures and descriptions of each step. B) Explain why RFLP can produce many bands on an electrophoresis gel and PCR (one set of primers) will only produce one or two bands on a gel for the same genome.
