A mutation is a permanent alteration in the DNA sequence that makes up a gene; that is, the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes...
Rather than being encyclopedic and all-inclusive, we have tried to focus on several selected genodermatoses for which there has been significant experimental work performed around identifying the genetic defect. Even this is not inclusive; for example, we have not discussed in details the very ...
Likewise, the usage of sex appears to [End Page 622] be a mechanism to avoid the negative consequences of accumulating mutations and not of much philosophic import, at least in a biological framework. The philosophic debates often appear to be about the nature of conceptual entities, such as ...

WT functions are robust to mutations that expand the substrate specificity. Accumulation of mutation in a single gene/protein leads to destabilization of the protein. EX. Beta-lactamase with M182T B-lactamase has higher tolerance than WT beta-lactamase Higher stability with high rate of mutation ...

比如你打算写一篇关于”Mutations in the promoter of the X gene increase the probability of prostate cancer metastasis."的文章,在introduction部分需要介绍X基因与前列腺癌转移间关系的背景知识。如果杂志/文章的读者主要是分子生物学家,介绍背景知识的时候你就需要多提供一些前列腺癌转移的知识,少讲一些关于X基因的...

[For the third type of combination, divide by six to cover the equivalent per- mutations (uds = usd = dus = dsu = sud = sdu).] So the total is n +n(n −1) +n(n −1)(n −2)/6 =n +n 2 −n +n(n −1)(n −2)/6 ...
