What causes genetic mutations?

Mutations are changes in the nucleotide sequences in a genome. Most often, these minor mistaks are corrected by in-built repair mechanisms and many mutations go unnoticed an are not harmful. Harmful mutations cause diseases in many cases. There are several factors that promote the formation of mutations. These factors are called mutagenic agents. Mutagenic agents are divided into: chemical and physical mutagens. UV radiation is an example of a physical mutagen and Nitrous acid is an expample of a chemical mutagen


What do enzymes must do to newly made DNA in order to correct mistakes or mutations?

proofread

Describe how gene mutations affect protein production.?

gene mutations can affect protein production through various mutations as nonsense mutations are any genetic mutation that leads to the RNA sequence becoming a stop codon. missense mutations are mutations that changes an amino acid from one to another. Slient mutations are mutations  that dont affect the protein at all.


Can mutations be predicted?
