The impact of a genetic mutation seems to depend on the rest of the gene sequence, and as other places in that sequence change, the effect of the mutation also changes. Reporting in Science , ...

E.coli bacteria, each cell trapped in a tiny tube, are giving researchers the chance to study the pace and effects of single genetic mutations. Most mutations, the scientists find, aren't harmful.

The age at which a patient presented with a myeloproliferative neoplasm, acquisition of JAK2 V617F homozygosity, and the balance of immature progenitors were all influenced by mutation order. As ...

Chemotherapy can increase mutation burden and change the cell population structure of normal blood, which contributes to long-term adverse effects such as second malignancies and infertility, ...

Mutations can be deleterious, neutral or, in rare cases, advantageous. The relative frequencies of these types across a genome constitutes the distribution of fitness effects. The properties of ...

Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments.

A mutation is a heritable change in the nucleotide sequence of an organism's DNA that ultimately serves as a source of genetic diversity. A single base change can create a devastating genetic ...

Teasing apart the effects of higher mutation load on fitness. American Association for the Advancement of Science (AAAS) Journal Science DOI 10.1126/science.aah5238. Keywords ...

Whole genome duplication (WGD) is a common mutation in plants with profound evolutionary potential. While it is well-known ...

Change in interactions with ACE2 between wt RBD and Southern African variant 501.V2. (A) position of the three amino acids (K417, N501 and E584) at the interface with human ACE2 in the WT RBD; (B ...
