_________ quickly rejoins double-strand breaks, but “cleaning” of the ends results in deletion of a few base pairs. _________ uses a newly-made sister chromatid as a template for perfect double-strand break repair.

You have discovered an “Exo–” mutant form of DNA polymerase in which the 3′-to-5′ exonuclease function has been lost, but the ability to join nucleotides together is unchanged. Which of these properties do you expect the mutant polymerase to have?

Transcription in bacteria differs from transcription in a eukaryotic cell because in bacteria

If the sequence of one strand of a DNA segment is 5′-G C C A C G T A T C A G-3′, what is the sequence of its complementary strand?

Adenine and thymine form _____ hydrogen bonds between them, while cytosine and guanine form _____ hydrogen bonds.

The chromosomes we typically see in images are isolated from mitotic cells. These mitotic chromosomes are in the most highly condensed form. Interphase cells contain chromosomes that are less densely packed and

DNA polymerase has some functional constraints which greatly complicate the process of DNA replication. Which of these is NOT one of those limitations?

The most likely outcome of post-translational histone modifications or methylation of cytosines is

What do you predict would happen if you created a tRNA with an anticodon of 5′-CAA-3′, but which carries methionine, then added this modified tRNA to a cell-free translation system that has all the normal components required for translating RNAs?

Consider a lamina described by the region
