Answer - 2 (Two replicating fork)
Explanation - DNA replication is the process in which the double-stranded DNA replicates and makes a copy of itself during cell division.DNA of the circular bacteria chromosome is unwinded at the origin of replication that forms a replication bubble. The replication bubble is a replication fork, which is a Y-shaped junction. DNA replication is initiated at a single origin of replication later two replication forks are formed. These replication forks move in opposite directions as replication further proceeds.

Question 8 1 pts What is true about the replication forks formed at each replication origin? O At each fork, the replication machine opens up the double helix and uses each DNA strand to make new daughter strands. O Replication forks are X shaped. One replication fork is formed at each replication origin. O The two forks formed at each replication origin move in the same direction, working together to unzip the DNA double helix and replicating the DNA as...
How many replication forks depart from an origin of replication? one two three four five QUESTION 10 A new DNA strand elongates only in the 5 to 3 direction because DNA polymerase can only add nucleotides to the free 3'end. replication must progress toward the replication fork. the polarity of the DNA molecule prevents addition of nucleotides at the 3'end. Okazaki fragments prevent elongation in the 3 to 5 direction DNA polymerase begins adding nucleotides at the end of the...
