Transcription takes place in which part of the eukaryotic cell?

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?

Which of the following is the correct order of steps in PCR?

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.

True or False. According to the article “Epigenetics in Action” in Överkalix men that experienced food scarcity during their slow growth period (SGP) tended to have sons with an increase risk of dying through cardiovascular disease.

True or False. Pyrosequencing (next generation sequencing) requires the creation of populations of different sized fragments terminated by a ddNTP on the 3’ end.

In one of Mendel’s pea plants, seed shape and color are controlled by genes located on separate chromosomes where the round shape allele is dominant over wrinkled and the yellow seed color allele is dominant over green. After performing a dihybrid cross (F1 heterozygous at both genes) you observed 360 round, yellow; 115 round, green; 85 wrinkled, yellow; and 20 wrinkled, green F2 plants. If these traits were controlled by two independent genes with two alleles at each gene, what is the expected number of green-round seeds from this cross?

True or False. Methylation is associated with transcriptional repression.

True or False. Sanger sequencing uses fluorescent dyes rather than radioactive isotopes to detect DNA fragments.

True or False. DNA template strands are READ by DNA polymerase in the 3’ to 5’ direction.
