Matthew Meselson and Franklin Stahl performed an experiment using heavy isotopes and bacteria to determine which model DNA follows to replicate. Their results are evidence supporting which DNA replication model below?
| a. |
The parent DNA molecule is broken into its singular nucleotides from which new nucleotides are copied and then all nucleotides to come back together as one larger DNA molecule. |
|
| b. |
The parent DNA is mixed into each of the daughter strands such that both daughter molecules contain a mix of parental and new DNA in each complementary strand. |
|
| c. |
The parent DNA strands separate and act as templates for new strands to build onto, such that each resulting molecule is a hybrid of 1 parental strand and 1 daughter strand. |
|
| d. |
The parent DNA strands re-associate after acting as replication templates, forming one molecule of parental DNA and one molecule of daughter DNA. |

In a famous experiment, Matthew Meselson and Franklin Stahl grew E.coli cells in a medium containing only the "her isotope of nitrogen, SN. These cells were then transferred to a medium with the "light" isotope of nitrogen, "N. The results of the experiment supported the hypothesis of semiconservative replication, which was proposed by Watson and Crick. Heavy DNA ('N DNA), hybrid DNA, and light DNA (N DNA) can be separated by centrifugation. If cells containing 1SN DNA are transferred to...

3. Shown below is a double stranded DNA. Replicate this DNA fragment and show the products formed from this replication. Remember, in replication, each strand is copied into a new daughter strand. In your answer, indicate which strands are the new daughter strands (mark with D) and which strands are the already existing parent strands (mark with P as shown below). Label the 5’ and 3’ ends of all DNA. HINT: You should have 2 double-stranded DNA fragments after replication....

Which of the following statements about DNA replication is FALSE? Primase synthesizes the primers. DNA polymerase is required to add new nucleotides to the growing ends of the DNA strands. DNA ligase joins the small DNA fragments of the lagging strand. Only one strand of the parent DNA serves as a template for a newly synthesized complementary strand.

Why were Meselson and Stahl unable to distinguish between the dispersive and the semiconservative models following only one round of DNA replication? 2. Describe in order, the four repeating steps that repeat over and over on the discontinuous lagging strand of DNA replication and name the major proteins required to carry out each of these steps in E. coli.
