Use the results of a PCR from DNA extracted from cheek cells of students and run on a gel shown below to determine what you would expect if this population is in Hardy-Weinberg Equilibrium (HWE). The ‘A’ allele is 50 base pairs longer than the ‘a’ allele. Remember samples are loaded at the top of the gel.

Short DNA strands that are complementary to DNA sequences on either side of the gene or DNA sequence of interest are synthesized and used to initiate its amplification in vitro by a special (heat-stable) DNA polymerase in a procedure known as:

True or False. Acetylation of histones is correlated with decreased gene expression.

The coefficient of relationship is best represented by which of the following?

Transcription takes place in which part of the eukaryotic cell?

Seed capsule shape in Shepard’s Purse is controlled by two genes where dominant allele at either of these genes will produce the triangular phenotype.

True or False. In a PCR reaction dNTPs are the nucleotide building blocks used to manufacture the new strand of DNA. In contrast, in a sequencing reaction both dNTPS and ddNTPs are used.

What is the coefficient of inbreeding of A?

True or False. Methylation is associated with transcriptional repression.

Bateson and Punnett mated purple sweetpeas with white sweetpeas. F1 hybrids were all purple in color. When the hybrids were mated, a ratio of 9 purple : 7 white were observed in the F2 generation. Which of the following could best explain this observation?
