AP Bio quiz

unwinds the parental double helix at replication forks

binds to and stabilizes single-stranded DNA until it is used as a template

breaks, and rejoins parental DNA ahead of replication fork, relieving the strain.

lays down the RNA primer (synthesizes)

synthesizes a new DNA strand by adding a nucleotide to an RNA primer or a per-existing DNA strand.

removes RNA primers and sticks in bases, replaces them with DNA nucleotides

gap in the sugar phosphate backbone, will join okazaki fragments in lagging strand, and in leading strand will join 3’ end of DNA that replaces primer to the rest of leading strand DNA

segments of lagging strand

discontinuously synthesized DNA strand that elongates by means of okazaki fragments synthesized away from the replication fork

the new complementary DNA strand that is synthesized continuously along the template strand toward the replication fork

the leading strand

the lagging strand
