The many available crystal structures of RT reveal that, generally, in relation to their binding sites NRTI resistance mutations are generally more distally positioned, whilst for NNRTIs mutations are clustered.
ATR-X patient mutations are generally hypomorphic and do not cause chromosomal instability[4].
However, microdissection and sequencing of breast cancer samples suggest that p53 mutations are generally, if not virtually always, clonal within breast cancer [30], [31].
It is possible the residual FTO in the peripheral tissues may be enough for its function, considering Fto heterozygous knockout mice, as well as humans heterozygous for the FTO loss of function mutations are generally normal [37].
Note that this model does not require structural mutations in CEA or CEACAM6 themselves and, in fact, such mutations are generally not observed in cDNAs derived from human tumors over-expressing these molecules [1].
Thresholds for expression of abnormal SC bristle numbers were modeled based on known Hsp90 genetics and biochemistry, bristle development pathways and a set of simple assumptions of threshold trait models: 1) Loss-of-function mutations are generally recessive to wild-type alleles.
Because mutations are generally considered the principal cause of changes in viral fitness and other phenotypic alterations [17], [18], [19], [20], [21], [22], [23], we compared the consensus nucleotide sequence of each clone before and after being subjected to large population passages.
The inability to predict positive selection on a gene in one lineage by identifying elevated dN/dS ratios in the orthologue within another lineage needs to be noted, as it reflects that adaptive mutations are generally rare events that lead to fixation in individual lineages.
Synonymous mutations are generally neutral in the course of evolution and do not result in changes to the amino acids in a protein, while non-synonymous mutations can occur under strong selective pressure and result in the altering of the amino acids in a protein.
These mutations are generally mutually exclusive.
