DNA replication Flashcards
1
Q
list the steps of DNA replication
A
pair of templates: complimentary to each other
hydrogen bonds broken: strands unwind and separate
Each strand acts as a template: formation of companion s.
Results in two pairs of strands exactly alike
2
Q
list steps of replication of circular DNA
A
begins at a single origin
with two replication forks
proceeds bi-directionally around the circle
3
Q
what are replicons?
A
multiple replication units
4
Q
what is a pre-replication complex?
A
origin recognition complex (ORC), binds to a replication origin
minichromosome maintenance complex (MCM) contains enzymes
