What types of error occur during replication and how are they repaired?
Homework Answers
Errors in DNA replication can be of various types ,however typically spin around the expansion of a nucleotide with the erroneous base, which means the matching between the parent and girl strand bases isn't correlative. The expansion of a mistaken base can happen by a procedure called tautomerization. A tautomer of a base gathering is a slight improvement of its electrons that takes into account diverse holding designs between bases.
On the off chance that DNA gets harmed, it can be repaired by different systems, including chemical reversal, excision repair, and double stranded break repair.

For these 4 examples, what will be the result after replication if not repaired? Also note if it results in a transition or transversion: a. In a C:G base pair, an adenine tautomer is placed across from the cytosine during replication b. In a T:A base pair, the adenine undergoes tautomerization prior to replication c. In a T:A base pair, 5-bromouracil is incorporated across from an adenine prior to replication d. In an A:T base pair, oxoG is placed across...

Which of the following damaged templates encountered by a replication fork is repaired by double-strand break repair? The replication fork encounters a lesion and translesion synthesis occurs. The replication fork encounters a lesion and stalls. The replication fork encounters a lesion and bypasses it, restarting synthesis on the other side of the lesion. The replication fork encounters a lesion at which repair has been initiated but not completed and the fork collapses.
