Frameshift mutations only occur in the coding region of the DNA sequence as the changes in the non-coding or regulatory regions of the genome produce no change in the protein. Causes of Frameshift Mutation Frameshift mutations are caused by the addition or deletion of nucleotides from a DNA sequ...
Silent mutation A frameshift mutation is a type of gene mutation wherein the addition or deletion of (a number of) nucleotide(s) causes a shift in the reading frame of the codons in the mRNA. This leads to the alteration in the sequence of amino acids during protein translation. A nonsens...
Insertional mutations are a type of frameshift mutation. In a frameshift mutation, all of the codons downstream from the mutation are changed, which generally produces significant changes in the protein. This is because inserting a new nucleotide shifts the reading frame for all codons after it. ...
You can identify a silent mutation by seeing if the mutation has any effect on the protein's structure or function. A silent mutation is a mutation that has no effect on the protein made. Silent mutations are possible due to redundancy in the genetic code. What are some example...

a type of MUTATION in which genetic material is removed from chromosomes or other DNA molecules (see CHROMOSOMAL MUTATION, POINT MUTATION). The deletion can be as small as a single DNA base (which can cause a misreading of the base sequence during PROTEIN SYNTHESIS, see FRAMESHIFT) to a lar...

development and structure of the progeny. a mutation in biology is a modification of the nucleic acid sequence of a virus, extrachromosomal dna, or the genome of an organism. the observable traits of an organism (phenotype) may or may not change as a result of a mutation. q2 define ...
This result suggests that the two mutations directly affect pre-mRNA splicing and the definition of exon 8. Exon 8 skipping (r.710_792del) results in a frameshift mutation (p.Asp237Glyfs*4). Download: Download high-res image (287KB) Download: Download full-size image Fig. 1. ...
