Which mutation leads to cell death regardless of what nucleotide is altered in the DNA strand?

Homework Answers

Answer #1

cells with base change mutations are more prone to get eliminated by apoptosis ( Programmed cell death). After a mutation occur it goes to immediate repair response where replication, cell division, transcription etc all processes get halted. Only after repair things get to normal or otherwise elimination of cell. In case of base mutation enzyme cannot recognise mutation and it remains in DNA. It lead to abnormalities in cell function which ultimately leads to cell death as soon as abnormalities recognised by apoptotic factors.

During DNA replication, after adding each nucleotide to a new strand of DNA, DNA polymerase checks that the nucleotide it just added is the correct one, i.e. that it is complementary to the opposite nucleotide on the template strand. This activity is called the ____________ activity of DNA polymerase. If this activity detects that a wrong nucleotide has been added, then the _____________ activity of DNA polymerase is activated, allowing the wrong nucleotide to be removed.
