Effects of failures all through DNA replication

One characteristic of DNA molecule is its replication ability. What are the effects of failures all through DNA replication?

E

Expert

Verified

Preferably a DNA molecule must replicate in a perfect manner. Sometimes though failures in the duplication take place, with alteration (that is, deletion, addition and substitution) of one or more nucleotides in the molecule.

Such mistakes, or mutations, thus make modifications in the protein synthesis procedure too. For illustration, the production of a significant protein for cells or tissues might be suppressed; new utile or inutile proteins can be formed and so on. The mistake in DNA duplication and the resultant production of modified genetic material are a few of the main creative forces for the biological evolution and the variety of species.
