Mutation False

A false mutation is a phenomenon that occurs when mutagenic factors enter the genome, leading to a change (change) of codons and a change in the amino acid sequence of the protein due to the presence of a homologue in the locus. The mutagenicity of a homologue lies in its ability to influence the main structural protein of the macromolecule, i.e. change the degree of manifestation of the mutation.

The effect of a false mutation differs from the effect of similar chemical mutagens: if each individual DNA molecule encounters mutations induced by a chemical agent (mutagenic factor) in sufficient quantities to cause a mutation with a random probability, then the homolog can easily displace or suppress the action of the mutagenic factor in the genome, without causing mutation changes (mutable tissue). In addition, mutations resulting from the combined action of a mutagen and a homologue are usually much less important (substantially more severe) than those resulting from the mutagen alone.

Mechanisms of gene control, which explain the fact that a mutation (usually expressed in the replacement of a functional group at the axinon level), appears equally in both mutable and resistant tissues, and also allows us to explain the mechanisms of gene protection from damage.
