Section 3 Review on 202

Describe what happens at a DNA replication fork during replication. The replication forks guide the enzyme.

Describe the role of  helicases and DNA polymerases during DNA replication. The helicase "unzips" the DNA, and the helicase synthesizes the DNA.

State why DNA replication is a semi-conservative process. It's a semi-conservative because it only makes a strand that is half new, and half old.

Compare the number of replication forks in prokaryotic and eukariotic DNA during replication. There are only two replication forks in a prokaryotic but in an eukarotic, there are many.

How are replication errors corrected? They are corrected using translation.

Why are there two DNA polymerases at one replication fork? Because there are only need one replication bubble.

Why are DNA repair enzymes important to an organism's survival? They are important because if there is an error, the organism will die, so they need to be repaired.
Is a mutation that occurs during the formation of an egg cell or sperm cell more significant than a mutation that occurs in a body cell? Explain. I think that a mutation in a egg cell or a sperm cell would be more significant because it ruins the entire baby, and if there is one in a body cell, it could be corrected.
