- Give only typing answer with explanation and conclusion Semi-discontinuous DNA replication, in the intact chromosomes of rapidly-growing bacterial cells, was first demonstrated by which of the following investigators? A. Rosalind Franklin and Maurice Wilkins B. Matthew Meselson and Franklin Stahl C. Erwin Chargaff and Arthur Kornberg D. Reiji Okazaki and Tuneko Okazaki E. James Watson and Francis CrickGive only typing answer with explanation and conclusion You are studying a strain of bacteria that carries a temperature-sensitive mutation in one of the genes required for DNA replication. The bacteria grow normally at the lower temperature, but when the temperature is raised they die. When you analyze the remains of the bacterial cells grown at the higher temperature you find evidence of partly replicated DNA. When the strands of this DNA are separated by heating, numerous single-stranded DNA molecules around 1000 nucleotides long are found. Which of the proteins listed below are most likely to be impaired in these mutant bacteria and why?: Primase, Helicase, or DNA Polymerase?Give only typing answer with explanation and conclusion A circular double-stranded DNA molecule contains 4200 base pairs. In solution the molecule is in a B-form helix, with about 10.5 base pairs per turn. The DNA circle has 12 superhelical turns. Part A What is its superhelix density σ?

- In the process of DNA replication, there are four important enzymes. Construct a table, provide what the four enzymes are, and explain how they function in DNA replication.Suppose DNA polymerase synthesizes DNA at a rate of 1130 bases per minute in a new strain of E. coli. It takes the new strain 40 minutes to replicate their chromosome. How many nucleotides are in the chromosome? Calculate the length of the chromosome given the diagram.Describe three (3) effects on DNA replication if DNA polymerase could build DNA in both directions – in both the 5’ to 3’ direction and the 3’ to 5’ direction.
