Homework Answers
Ans. At each fork, the replication machine opens up the double helix and uses each DNA strand to make new daughter strands.
Only first is true. Replication forks are Y shaped. DNA replication can be bidirectional and two forks formed at each origin move in opposite directions.

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...

For questions 1 and 2, please remember that there are two replication forks per origin, and that the synthesis of the two new daughter strands occurs at the same rate and at the same time. 1. (4 points) The pathogenic strain O157:H7 of E. coli has one circular chromosome. The DNA molecule in this chromosome contains 5,498,450 bp. DNA synthesis at one replication fork occurs at a rate of 70,000 nucleotides per minute. How many minutes will it take to...

Draw a figure of one double stranded DNA molecule that has initiated replication and produced two okazaki fragment in each lagging strand. The figure must include both template strands, all newly synthesized DNA molecules on both leading and lagging strands, all RNA primers, direction of chain growth for each fragment/strand indicated with arrowheads, direction of replication forks. Each molecule must be labeled with the origin of replication on both strands, leading and lagging strands labeled, template or newly synthesized, DNA...

Which of the following statement about DNA is FALSE? When bacteriophage DNA was shown to be the agent necessary for production of new phages, this was the early experiment demonstrating that DNA is the hereditary material. During DNA replication, two replication forks are formed to complete the synthesis of the entire chromosome in eukaryotes. During bacterial DNA replication process, replication forks move in opposite directions away from the origin of replication The molecular structure of DNA...

Incorrect Question 3 0/1 pts The replication fork has both leading (continuous) and lagging (discontinuous) synthesis because: a. The origin of replication only allows DNA synthesis to occur in one direction around the chromosome. b. Primase only works on the leading strand c. Helicase is slow in unwinding the double helix so the polymerization moving toward...
