Sentence examples for more genetic changes from inspiring English sources

Any reassortant would likely need more genetic changes, such as ones that made the 1957 and 1968 strains better able to bind to human respiratory tract epithelial cells, the CDC team reports today in the Proceedings of the National Academy of Sciences.

Contemporary models of bladder TCC progression suggest that tumours of a higher stage and grade have accumulated more genetic changes (Simon et al, 1998).

In general, more advanced tumors exhibit more genetic changes, although many of the changes are already present in in situ carcinomas or even in ductal hyperplasia, suggesting a progressive accumulation of genomic aberrations.

Thus, differences in the allelic loss and mutation patterns have been reported previously between squamous and adenocarcinomas, suggesting that more genetic changes accumulate during tumorigenesis in squamous cell carcinomas than in adenocarcinomas (Sato et al, 1994).

The large number and variety of structural variants seen in this relatively simple model of prostate cancer also indicates that many more genetic changes are waiting to be discovered in clinical prostate cancer as it progresses to the aggressive disease.

However, multigenic inheritance, resulting from the combination of two or more genetic changes, each imparting a low to moderately increased risk of developing dystonia and acting in combination with environmental factors, may also underlie a significant proportion of the apparent heritability of late-onset dystonia.

The more genetic change an order has undergone from the hypothetical ancestral bird, the greater the distance it travels.

But only half of the comparisons with a significant difference in branch length show more genetic change in the domesticated lineage, a pattern indistinguishable from chance.

Although researchers already knew that certain cancer drugs work on only patients with specific mutations in their tumors, whole genome sequencing could help identify more such genetic changes, he says.

Other genetic data have shown that the human population remained smaller than that of the chimpanzee for most of the last 1 million to 2 million years, he notes, and as population genetic theory predicts, recombination will produce more adaptive genetic changes in larger groups.
