1.What is the term for direction of DNA replication fork movement?
2. What is the structure that is form by some Gram positive organism when the cells form a dormant state?
Homework Answers
1. Leading strand is synthesized in 5'-3' direction moving towards the replication fork while lagging fragments are synthesized in 3'-5' direction which discontinuously synthesized in opposite direction leads to okazaki fragments . These fragments are then ligated by DNA ligase.
2. Endospore formation is usually triggered by lack of nutrients and usually occurs in gram positive bacteria. In endospore formation, bacterium divides within its cell wall, then one side engulfs the other. Endospore enable bacteria to lie dormant for extended periods, even centuries.
I hope this will help you if you really like it then give me a thumbs up, thank you!

The speed of DNA replication at a replication fork is about 100 nucleotides per second per standin human cells. What is the minimum number of origins of replication that a human cell must have in order to replicate its DNA once every 24 hours? Recall that a human cell contains two copies of the human genome, one inherited from the mother and one from the father, each consisting of 3 x 109base pairs.

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...
