Sentence examples for dnas that control from inspiring English sources

The study of cis-regulatory DNAs that control developmental gene expression is integral to the modeling of comprehensive genomic regulatory networks for embryogenesis.

Rather, they are in strands of DNA that control whether genes are switched on or off.

Some of them may contain stretches of DNA that control neighboring genes.

The researchers planned to compare the genomes of different wheat varieties to find the segments of DNA that control particular traits, such as fungal-disease resistance and tolerance to heat and drought.

Epigenetics is the study of mechanisms, other than alterations in the underlying sequence of DNA, that control a gene's expression.

Not only does the work provide a molecular basis for flaxen locks, but it also demonstrates how changes in segments of DNA that control genes, not just changes in genes themselves, are important to what an organism looks like.

The term epigentics refers to chemical changes to DNA that control the activity of genes, turning their expression on or off, for example; in one kind of epigenetics, chemicals called methyl groups can attach to DNA and block it from being transcribed into a protein.

The findings from ENCODE are starting to show that many of these candidates for disease susceptibility are in parts of the junk DNA that control expression of key genes in relevant cell types.

He pointed to a study at University College London that identified 'high performance genes', a sequence of DNA that controls metabolic efficiency.

They took a fragment of DNA that controlled the production of a collagen gene from the tiger and inserted it into a mouse embryo.

Or the change might be in a poorly understood region of DNA that controls genes rather than in a gene itself.
