Silent mutation
Silent mutations are DNA mutations that do not result in a change to the amino acid sequence of a protein. This kind of mutation may occur in a noncoding region (outside of a gene or within an intron), or they may occur within an exon in a manner that does not alter ...

DNA
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions of an organism. These genetic instructions are used in the development and functioning of all known living organisms and some viruses. DNA Stores Information The main role of DNA molecules is the longterm storage ...

Point mutation
point mutation, or substitution, is a type of mutation that causes the replacement of a single base nucleotide with another nucleotide. Often the term point mutation also includes insertions or deletions of a single base pair (which have more of an adverse effect on the synthesized ...

Nonsense mutation
nonsense mutation is a frameshift mutation in a sequence of DNA that results in a premature stop codon, or a nonsense codon in the transcribed mRNA. Often this mutation produces a truncated, and often nonfunctional, protein product

nonsense-mutation, mutations, mutation

Neutral mutation
neutral mutation is a mutation that occurs in an amino acid codon (presumably within an mRNA molecule) which results in the use of a different, but chemically similar, amino acid. This is similar to a silent mutation, where a codon mutation may encode the same ...

Mutation
biology, a mutation is a change to the nucleotide sequence of the genetic material within an organism. What causes mutations? Mutations can be caused by: copying errors in the genetic material during cell division, exposure to ultraviolet or ionizing radiation, chemical mutagens, or viruses ...

Missense mutation
Missense mutations or nonsynonymous mutations are types of point mutations where a single nucleotide is changed to cause substitution of a different amino acid. This in turn can render the resulting protein nonfunctional. Such mutations are responsible for diseases such as Epidermolysis bullosa, sicklecell disease, and SOD1 ...
