Sentence examples for means that mutations from inspiring English sources

It also means that mutations will continue to occur even after previous beneficial mutations have become fixed.

The polyploid nature of mtDNA means that mutations often co-exist with their wild-type counterpart in various proportions (termed heteroplasmy).

This means that mutations in p53 are beneficial for response to radiotherapy as DNA damage would not be repaired and thereby overall patient survival would be improved.

Mutants of C. elegans with widespread nervous system defects are often viable, which means that mutations in a large number of neuronal genes can be tested for altered behaviors in genetic screens.

A recent study shows that a loss of Apaf-1 or caspase-9 does not prevent apoptosis in cells of the haematopoietic system and does not rescue the clonogenic potential upon treatment with cytotoxic agents (Marsden et al, 2002); this means that mutations in the apoptosome are unlikely to contribute to malignant transformation in this cell type.

The ω parameter established the role of positive and negative selection affecting gene sequences: An estimate of d n higher than that for d s means that nonsynonymous mutations are fixed at a higher rate than synonymous ones and that positive selection is at work.

As Rice (2004) points out, this means that mutation, selection and migration can each be represented by a vector field on the space of gene frequencies; their combined effects on the overall evolutionary change is then represented by ordinary vector addition.

The deletion of a full-length structure means that mutation and recombination remove so many structural characters of a full-length element that it can not be recognized any more.

Rather is meant that mutations do not occur according to need.

We interpret such rescue to mean that mutations in the GLS do not interfere with gurken transcription or translation, but rather only mRNA localization.

This would mean that mutations at amino acid sites Q91 and E226 (numbering based on BSP165 MAN) might be involved in an evolutionarily critical change in the pH optimum for GH5-8 mannanases.
