However, when existing mutations are few but have been amplified, they might be missed.
Therefore, this and the other evolving populations must have fairly quickly incorporated mutations that provided the greatest gains, and their slower subsequent adaptation reflects beneficial mutations that are fewer in number, smaller in effect, or both [ 1, 14].
Experiments assessing the effect of sex on mutation clearance are fewer.
First, there are fewer mutations and structural variants in paediatric cancers than in adult cancers.
Specifically, Chapman et al. (2011) discovered that there are fewer mutations observed in genes that are expressed at a higher level on average in cancer cells.
Instead, the pronounced deceleration in its rate of fitness improvement indicates that the population early on incorporated most of those mutations that provided the greatest gains, and subsequently relied on beneficial mutations that were fewer in number, smaller in effect, or both.
Results show that while some semantic entities, such as genes, proteins and chemicals are consistently annotated in many collections, corpora available for diseases, variations and mutations are still few, in spite of their importance in the biological domain.
If there are few mutations elsewhere in the gene (where they can be determined more reliably) the likelihood of a mismatch in the junction being due to a mutation is small.
When 2 or fewer oncogenic mutations are required, non-mutator pathways predominate.
And the vast majority of newly discovered mutations are rare, occurring in fewer than 5percentt of specific cancers.
