What is the relationship between DNA polymerases and mutations in DNA?

Answer 1

DNA polymerases adds complimentary bases during DNA replication; however, there can be transcription errors. Mutations occur when changes in the genetic materialproduce abnormal genetic coding's. For instance, point mutation is defined by a change in just one base pair; because the bases cannot code for an amino acid, abnormal proteins are formed in place of normal ones.

Answer 2

DNA polymerases aid in the synthesis of a new DNA strand to the old strand during replication - adding base-by-base. If the wrong base is inserted into the daughter strand, then a mutation has occurred. Some polymerases have a "proofreading" ability and will recognize and fix the incorrectly-placed base-pairs, but some mutations may remain.

Answer 3

it is that you can tell me the facking answer cause i dont know it

Answer 4

Any changes to parts of the DNA which carry codes called genes, can cause mutations. These changes may not help the cell work properly.
