A frameshift mutation can drastically change the coding capacity (genetic information) of the message. [1] Small insertions or deletions (those less than 20 base pairs) make up 24% of mutations that manifest in currently recognized genetic disease. [10] Frameshift mutations are found to be more common in repeat regions of DNA.
The frameshift occurs due to wobble pairing. The Gibbs free energy of secondary structures downstream give a hint at how often frameshift happens. [7] Tension on the mRNA molecule also plays a role. [8] A list of slippery sequences found in animal viruses is available from Huang et al. [9]
Protein-truncating variants (PTVs) are genetic variants predicted to shorten the coding sequence of genes, [1] through ways like a stop-gain mutation. [2] [3] [4] [5 ...
The Crick, Brenner et al. experiment (1961) was a scientific experiment performed by Francis Crick, Sydney Brenner, Leslie Barnett and R.J. Watts-Tobin. It was a key experiment in the development of what is now known as molecular biology and led to a publication entitled "The General Nature of the Genetic Code for Proteins" and according to the historian of Science Horace Judson is "regarded ...
In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping. Insertions can be anywhere in size from one base pair incorrectly inserted into a DNA sequence to a section of one chromosome ...
Neomorphic mutations are a part of the gain-of-function mutations and are characterized by the control of new protein product synthesis. The newly synthesized gene normally contains a novel gene expression or molecular function. The result of the neomorphic mutation is the gene where the mutation occurs has a complete change in function. [56]
In the case where a frameshift results in nonsense, the nonsense-mediated mRNA decay (NMD) pathway may destroy the mRNA transcript, so frameshifting would serve as a method of regulating the expression level of the associated gene. [6] If a novel or off-target protein is produced, it can trigger other unknown consequences. [4]
An open reading frame (ORF) is a reading frame that has the potential to be transcribed into RNA and translated into protein. It requires a continuous sequence of DNA which may include a start codon, through a subsequent region which has a length that is a multiple of 3 nucleotides, to a stop codon in the same reading frame.
