Florida International University CHM 4220 EXAM 2 Chapter 12 Q&A Fall 2023/2024. 1. What are the two major conditions for genetic information being accurately copied every time a cell divides? 1. it has to be extremely accurate. 2. it has to take place at a high speed. 2. What were 3 models of DNA replication proposed and which one was confirmed valid? 1. conservative replication model 2. dispersive replication model 3. semiconservative replication model semiconservative replication mode...

Who performed classic experiments that supported the semiconservative model of DNA replication? - Meselson and Stahl What separates the DNA strands during replication? - helicase A new DNA strand elongates only in the 5' to 3' direction because - DNA polymerase can only add nucleotides to the free 3' end. What is the role of DNA ligase in the elongation of the lagging strand during DNA replication? - It joins Okazaki fragments together

chapter 14 review questionsIf DNA of a particular species was analyzed and it was found that it contains 27 percent A, what would be the percentage of C? a. 27 percent b. 30 percent c. 23 percent d. 54 percent C The experiments by Hershey and Chase helped confirm that DNA was the hereditary material on the basis of the finding that: a. radioactive phage were found in the pellet b. radioactive cells were found in the supernatant c. radioactive sulfur was found inside the cell d. r...

The process of DNA replication requires that each of the parental DNA strands be used as a _____ to produce a duplicate of the opposing strand - CORRECT ANSWER-(c) template DNA replication is considered semiconservative because - CORRECT ANSWER-(c) each daughter DNA molecule consists of one strand from the parents DNA molecules and one new strand (d) true, but not correct - new DNA strands must be copied from a DNA template The classic experiments conducted by Meselson and Stahl demons...
