MispairingThe presence of a
nucleotide in one
nucleotide chain of a
DNA molecule, which is not the
complement of that at the corresponding position in the other chain.

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.
Full article >>>These high rates of
mutation can be explained most frequently by slipped
strand mispairing (slippage) during
DNA replication on a single
DNA double helix.
Mutation may also occur during
recombination during
meiosis [4].

transition can be caused by nitrous acid,
base mispairing, or
mutagenic
base analogs such as 5-bromo-2-deoxyuridine (BrdU). Less common is a
transversion, which exchanges a
purine for a
pyrimidine or a
pyrimidine for a
purine (C/T ↔ A/G).

mispairing during
replication.
The inherent chemical instability of
nucleotides is sufficient that, if uncorrected, the information in
genomes would degenerate in a few generations.

inversions of
chromosomes 1, 2, 9, and 18, as well as the par

chromosome 7q11/q22. From this, we infer that meiotic
