In response to a double-stranded DNA break, which type of nuclease generates the 3' overhangs that will go on a homology search?
A. 5'-to-3' Exonuclease
B. 5'-to-3' Endonuclease
C. 3'-to-5' Exonuclease
D. 3'-to-5' Endonuclease
Homework Answers
Answer
Option A is the right answer because 5' to 3' exonuclease will generate the 3' overhangs.

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....

6a. Dissociation of the double stranded DNA helix into single coils is referred to as DNA melting. In this process, two strands of a DNA molecule can be separated by heat without breaking any covalent bonds. Every unique DNA molecule “melts” at a different temperature. Determine the order of the DNA sequences listed below according to relative melting temperatures (lowest Tm to highest Tm). Assume that they all begin as stable double-stranded DNA molecules.
