What is a frameshift mutation in DNA coding? Review the types of mutations, and find out what causes a frameshift mutation and some examples of their effects. Related to this Question What is mutation in biology? What are two kinds of frameshift mutations?
MutationHot TemperatureA series of ultraviolet light-induced revertants from the mutant am6, mapping at the left-hand ("N-terminal") end of the structural gene for NADP-specific glutamate dehydrogenase, have been shown to have amino acid substitutions in the N-terminal tryptic peptide. Only a ...
Transversion, in molecular biology, refers to a point mutation in DNA in which a single (two ring) purine (A or G) is changed for a (one ring) pyrimidine (T or C), or vice versa. A transversion can be spontaneous, or it can be caused by ionizing radiation or alkylating agents. ...
A frameshift mutation is a type of genetic mutation resulting from the alteration of a number of nucleotides in DNA sequences that are not multiple of three.

Key Point About Mutation ▪ The effect of a mutation can range from silence to destruction of the polypeptide or deletion of the gene; the effect of the mutation is determined by where in the mRNA the change occurred and what the new codon specifies (e.g., a termination codon vs. an ...
An unrelated patient had a different heterozygous frameshift mutation in the CAV1 gene, designated -88delC. He also had a partial lipodystrophy phenotype, with subcutaneous fat loss affecting the arms, legs and gluteal region, but sparing his face, neck and visceral fat stores. He also had ...
The immune system can recognize and attack cancer cells, especially those with a high load of mutation-induced neoantigens. Such neoantigens are abundant in DNA mismatch repair (MMR)-deficient, microsatellite-unstable (MSI) cancers. MMR deficiency leads to insertion/deletion (indel) mutations at co...
