Can polymerase catch and correct every reptication error?

Answer 1

Yes. Initially, DNA replication makes 1 mistake in a 100,000. Like spell check, DNA polymerase comes in and removes errors in base pairs and correct them by adding the right ones. After DNA polymerase checks the new strand for errors, the end result is 1 mistake in a billion. If this didn't occur, mutations would surely take place in out body.

Answer 2

No, polymerase cannot catch and correct every replication error. While polymerase has proofreading capabilities to help catch and correct mistakes, it is not infallible and some errors may still occur. Additionally, other mechanisms such as mismatch repair systems are also involved in correcting replication errors.

Answer 3

Error correction is a property of some, but not all, DNA polymerases. This process corrects mistakes in newly synthesized DNA. When an incorrect base pair is recognized, DNA polymerase reverses its direction by one base pair of DNA. The 3'-5' exonuclease activity of the enzyme allows the incorrect base pair to be excised (this activity is known as proofreading). Following base excision, the polymerase can re-insert the correct base and replication can continue.

Answer 4

No, it can't, as they obviously exist quite commonly.

Answer 5

DNA polymerase has a enzyme function that enables it to detect errors and correct them.

Answer 6

No, that is why there are disorders. Such as Down syndrome etc.

Answer 7

Although DNA polymerase is very good at catching and fixing errors, it can still pass some by. These errors, however, rarely affect the person as a whole and are quite uncommon.

Answer 8

Yes, in most of the cases DNA polymerases have proof reading ability and correct the error in DNA replication.

Answer 9

Proofreading
