mutation are caused by radiation and are 99.9% harmful
all mutations in terms of DNA happen in a gene. here it has to be noted that a gene is made up of two strands of nucleotides which are made up of amino acids. when mutations occur the sequence of nucleotides may change. sometimes a nucleotide may become missing hence the sequence of the strands change. mutations can be harmful but also very beneficial.
The three main types of gene mutations are point mutations, insertion mutations, and deletion mutations. Point mutations involve changes to a single nucleotide base. Insertion mutations involve the addition of extra nucleotide bases. Deletion mutations involve the removal of nucleotide bases in a gene sequence.
gene mutations
More serious than what? Mutations happen all the time and have done so.
The mutations that confer a selective growth advantage to the tumor cell are called “driver” mutations. It has been estimated. A driver gene is one that contains driver gene mutations. But driver genes may also contain passenger gene mutations A typical tumor contains two to eight of these "driver gene" mutations; the remaining mutations are passengers that confer no selective growth advantage.

mutations
Random mutations of DNA happen and these get inserted into the gene pool as the species breed.
For individuals with MTHFR gene mutations, the best form of B12 is methylcobalamin.
Such mutations are called point mutation or gene mutation.
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.
Mutations are permanent.
