Many things can cause mutations like Radiation,Changing habitat[eg.The Peppered moth],and of course by constant change from generation to generation.
Mutations that occur at a single point in the DNA sequence are Point Mutations.
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
The specific type of mutation resulting from a mistake during DNA replication will depend on the nature of the mistake and the type of nucleotide substitution that occurred. Some possible types of mutations include point mutations (such as a substitution, insertion, or deletion of a single nucleotide), frameshift mutations, or silent mutations.
Generally in a way that's far too complicated to give a single answer for.
Mitochondrial myopathies typically affect tissues with high energy demands, such as skeletal muscles, heart muscles, and the central nervous system. Symptoms may include muscle weakness, exercise intolerance, and neurological problems due to impaired energy production.

Such mutations are called point mutation or gene mutation.

Mutations that occur at one single nitrogen base are referred to as a point mutation.
genetic variation originates from mutations on which evolution depends on.

No. Usually there have to be a lot of mutations which build up.
Point mutations are when a single nucleotide is replaced by a different one, but this doesn't affect the length of the DNA sequence, which usually will not affect the way the protein that is produced. A phase shift (what I think you meant) mutation is caused by an addition or deletion of a base that changes the length of the sequence. This causes problems because codons to make proteins are in sets of 3 and deleting a nucleotide makes the reading frame different and will add incorrect amino acids to the proteins from the mutation on, resulting in an ineffective protein.
Bacic Answer:Point mutations occur when a single nucleotode is replaced with another nucleotide tide base. Insertion and come in this category.More Detail Answer:Point mutations occur when a single nucleotide is replaced with another nucleotide tide base. Insertion and come in this category. Error in the process of replication of DNA molecule results in point mutations. Sometimes heat of high level radiation cause the error in DNA replication. There are different effects of point mutations. if this type of mutation occurs in the sequence of DNA molecule or exon, then the protein sequence changes present in the gene. If the mutation occurs in the RNA effecting the codon of gene Sickle cell anemia is cause by the point mutations. Changes occur in the beta hemoglobin. it converts GAC sequence into GUG, Point mutation can be subdivided into three types:1) Nonsense mutations are the ones which code for the same amino acid.2) Misssense mutations occur in the genes which code for different amino acid.3)Silent mutations do not affect the function of the protein and code for different of same amino acid.
