Missense mutations
With a
missense mutation, the new
nucleotide alters the
codon so as to produce an altered
amino acid in the
protein product.
Full article >>>Missense mutation A
mutation that changes a
codon for one
amino acid to a
codon for a different
amino acid, resulting in an
amino acid substitution in the
protein product.

mutation involving a

substitution within a
gene that changes a
codon, but the new
codon makes
sense in that it still codes for an
amino acid.

Full article >>>Three kinds of
point mutations can occur. A
mutation that results in an
amino acid substitution is called a
missense mutation.
A
mutation that results in a
stop codon so that incomplete
proteins are produced, it is called a
nonsense mutation.

Mitochondrial DNA -- the
mitochondrial
genome consists of a circular
DNA duplex, with 5 to 10 copies per
organelle.
Mitosis -- nuclear
division.
