The impact of an expressed somatic mutation depends upon which gene has been mutated.
The telltale appearance of truncated proteins indicates that the gene has been mutated and that the patient has at least the first signs of colon cancer.
The results may be due to the effects of physical and chemical mutagenesis on the original strain, the DNA which controlled extracellular traits has been mutated as well, but there was no significant change in the colony and cell morphology.
A crucial threonine thought to be involved in a short bromine-to-oxygen halogen bond to the inhibitors in the wild type has been mutated to the structurally similar residues alanine, cysteine, serine and valine.
Now, in the 14 May issue of Science, Kobayashi and his colleagues report that the same gene has been mutated in white grapes by a bit of pushy DNA, resulting in loss of skin color.
CK19CreERT encodes the Cre recombinase fused to a region of the estrogen receptor that has been mutated to bind tamoxifen.
This is exemplified most strongly by strains in which the A box internal control element has been mutated (Figure 2).
Cells in which either SBM1 or SBM2 has been mutated are viable and are wild type for response to MMS and HU.
Characterisation of the U line has shown that an active transposon-silencing process that targets ZAM and Idefix has been mutated in this line.
Subsequently, the wild-type gfp gene has been mutated to many forms to improve detection and expression of the fluorescent protein in eukaryotic and prokaryotic hosts [4].
Here, we have taken advantage of a transgenic mouse model in which a tyrosine motif in the cytoplasmic tail of MHC I has been mutated.
