Question
1. synthesis on the lagging strand versus the leading strand
2. synthesis on the leading strand versus the lagging strand
3. priming of DNA synthesis versus actual DNA synthesis
4. photorepair of DNA versus DNA replication
B-One common feature of all DNA polymerases is that they
1. synthesize DNA in the 3' to 5' direction
2. synthesize DNA in the 5' to 3' direction
3. synthesize DNA in both directions by switching strands
4. do not require a primer
C-Telomeres are an important feature of eukaryotic chromosomes because:
1. They ensure that RNA functions properly
2. Protect the integrity of linear chromosomes
3. They connect to other chromosomes to make a circular piece of DNA during replication
4. They replace distortions caused by thymine dimers
5. b and d only
Explanation / Answer
A-If the activity of DNA ligase was removed from replication, this would have a greater affect on 1. synthesis on the lagging strand versus the leading strand (Ligase is very nuch essential for the synthesis of lagging strand synthesis, becuase it connects the okazaki fragments.) B-One common feature of all DNA polymerases is that they 2. synthesize DNA in the 5' to 3' direction (All the polymerases direct the synthesis in the 5' to 3' direction only, because they need the free 3'OH to elongate the chain length.)(All the polymerases direct the synthesis in the 5' to 3' direction only, because they need the free 3'OH to elongate the chain length.) C-Telomeres are an important feature of eukaryotic chromosomes because:
2. Protect the integrity of linear chromosomes (Telomeres are the ends of the chromosomes, that maintain the unity of them.)
(Telomeres are the ends of the chromosomes, that maintain the unity of them.)
