Consider the following DNA sequence, which codes for the first portion of a long protein beginning at the ATG (AUG in mRNA) start codon. 5′ ATG CCC CGC AGT AGG GGG TGG AGA3′ A mutation occurs changing this sequence to: 5′ ATG CCC CGC AGT AGG GAG TGG AGA3′ What type of mutation is this? Explain. Hint: there could be multiple mutations to discuss for this response!

Consider a bird in which a high-pitched song (H) is dominant to a low-pitched song (h). You cross two birds that are heterozygous for the gene for song pitch. Predict the genotypes and phenotypes of the offspring.

In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the [nucleoid]. In contrast, in eukaryotes, all of the cell’s chromosomes are stored inside a structure called the [nucleus].

A mutation within a gene changes the start codon to a stop condon. This mutation will not affect transcription; however, it will affect translation by preventing the initiation of polypeptide synthesis.

A research studying corn finds that kernel color patterns are caused by DNA elements moving in and out of pigment genes. When only the Ds element is present, no transposition occurs. When both Ac and Ds are present, movement resumes. What explains this?
