Nonsense mutation:In this instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all. Silent mutations:These are muta...
This leads to the alteration in the sequence of amino acids during protein translation. A nonsense mutation is a form of mutation producing a nonsense codon. A nonsense codon, as the name implies, does not code for amino acid and it leads to a protein product that is early truncated. A ...
Define mutation. mutation synonyms, mutation pronunciation, mutation translation, English dictionary definition of mutation. n. 1. The act or process of being altered or changed. 2. An alteration or change, as in nature, form, or quality. 3. Genetics a.
作者: A. P. M?ller and T. A. Mousseau 摘要: Secondary sexual characters have been hypothesized to be particularly susceptible to the deleterious effects of mutation because the expression of such characters is usually influenced by many more metabolic pathways than are ordinary morphological ...
摘要: SummaryAn analysis of data on sex-linked recessive muscular dystrophy of the Duchenne type suggests that the mutation rate is greater in males than females. It cannot be much less.关键词:Muscles Disease DOI: 10.1111/j.1469-1809.1955.tb01289.x ...
A method to identify and analyze clonal hematopoiesis in clinical blood samples at single-cell resolution reveals cell-intrinsic and paracrine effects of DNMT3A mutations in circulating monocytes, T cells and natural killer cells in the setting of heart failure.

Molecular techniques have created the opportunity for great advances in plant mutation genetics and the science of mutation breeding. The powerful targeted induced local lesions in genomes (TILLING) technique has introduced the possibility of reverse genetics—the ability to screen for mutations at the ...

A section of Mutation Research Mutation Research (MR) provides a platform for publishing all aspects of DNA mutations and epimutations, from basic evolutionary aspects to translational applications in genetic and epigenetic diagnostics and therapy. Mutations are defined as all possible alterations … V...
