A young man developed a rare form of colon cancer. Genetic testing shows that neither of her parents carries mutations linked to colon cancer. Their cancer is most likely due to [blank1] mutations. Which factor most likely caused these mutations? [blank2]

“Splicing” is one way eukaryotic organisms regulate gene expression. What is involved in the process of splicing?

In a specific breed of cattle, a single gene controls muzzle (nose) pigmentation. The black muzzle allele (M) shows incomplete dominance with the pink muzzle allele (m). Heterozygous individuals (Mm) have a “dusky” (greyish-pink) muzzle. A second gene controls coat color. The red allele (R) and white allele (W) are co-dominant. Heterozygous individuals (RW) have a “roan” coat (a mix of red and white hairs). A rancher breeds a dusky-muzzled, roan bull with several dusky-muzzled, roan cows. Over several years, the rancher records the following phenotypic ratio in the calves: 24 black muzzle, red coat : 51 dusky muzzle, roan coat : 25 pink muzzle, white coat Part 1: Based on this observed ratio, are the two genes linked? [blank1] Part 2: If they are linked, what way are the alleles of the two genes linked? [blank2]

During DNA replication, our cells use the enzyme helicase to “unzip” the two strands that comprise the DNA molecule. To make copies of specific DNA sequences in the lab, scientists use polymerase chain reaction (PCR). PCR mimics DNA replication in some ways, but not in how the two strands are pulled apart. How are the two strands of DNA unzipped during PCR?
