During DNA replication, the leading strand is synthesized continuously, whereas
the lagging strand is synthesized as Okazaki fragments. Why is this so? - ANSWER-
-DNA synthesis can take place only in the 5' to 3' direction.
During DNA replication, an open section of DNA, in which a DNA polymerase can
replicate DNA, is called a _____ - ANSWER--replication fork
After replication is complete, the new DNAs, called _______ are identical to each
other. - ANSWER--daughter DNA
The enzyme that can replicate DNA is called _____ - ANSWER--DNA polymerase
What are the short sections of DNA that are synthesized on the lagging strand of
the replicating DNA. - ANSWER--Okzaki fragments
5. The new DNA strand that grows continuously in the 5' to 3' direction is called
the _____ - ANSWER--leading strand
What is the function of helicase in DNA replication? - ANSWER--It untwists the
double helix and separates the two DNA strands.
