A researcher used polymerase chain reaction (PCR) to test four individual nematodes for the presence of a mutation in Gene Y. When amplified, the fragments of DNA containing the mutated gene alleles were 250 base pairs long and the normal (wild type) alleles were 350 base pairs long. To identify the genotypes of the individual nematodes, the researcher used gel electrophoresis to visualize the PCR results. 1000 bp s00 bp 300 bp 200 bp 100 bp Remember that these nematodes are diploid organisms and as such, inherited two copies of Gene Y. Which of the following statements is a correct analysis of these results ) a) Nematode As homozygous for this gene and has two copies of the mutated allele. O b) Nematode C is heterozygous for this gene and has one copy of the mutated allele and one copy of the normal (wild type) allele. OC) Nematode Dis heterozygous for this gene and has one copy of the mutated allele and one copy of the normal (wild type) allele. O d) Nematode B is homozygous for this gene and has two copies of the normal (wild type) allele. Nematode A Nematode B Nematode C Nematode D DNA ladder

What could you conclude from PCR/DGGE analysis of a samplethat yielded one band by PCR and one band by DGGE? Oneband by PCR and four bands by DGGE?
DNA fingerprinting involves using restriction enzymes to cut DNA at a specific sequence, resulting in many fragments of different lengths. Gel electrophoresis then separates the fragments according to size. DNA fingerprints produced from four different individuals is shown below.The DNA for Individuals 3 and 4 could NOT be Select one: a. mitochondrial DNA from two people who have the same maternal grandmother (both their mothers had the same mother) b. mitochondrial DNA from two people who have the same paternal grandmother (both their fathers had the same mother) c. nuclear DNA from identical twins d. nuclear DNA isolated from a hair left at a crime scene and a buccal swab from a suspect who was present at the crime
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
