Sentences with phrase «response to environmental cues»

The researchers began their study as a way to explore epigenetics, a process by which organisms modulate their gene expression in response to environmental cues without changing the underlying sequence of their DNA.

«Our data suggests that, during development, relative brain parts change their size in response to environmental cues without affecting overall brain size: increasing certain parts forces others to decrease concurrently.

«We provide the first evidence that the PPARα - dependent gene Fgf21 demethylation occurs in the postnatal mouse liver, and once established it persists into adulthood and exerts long - term effects on the magnitude of gene expression response to environmental cues, which may account in part for the attenuation of diet - induced obesity (Figure).»

In an attractive synthesis, such neighborhood - level risk factors might impart lasting epigenetic changes — the chemical overwriting of the genome in response to environmental cues.

Bacterial chemotaxis, the process by which a bacterium changes direction in response to environmental cues, involves a complex array of chemical receptors (red, elongated molecules) and other sensory proteins (blue and green molecules), which work together to process sensory information.

The brain's ability to reorganize in response to environmental cues is known as plasticity, and it is this flexibility that allows us to learn things we never knew at birth; how to tie our shoes, for example, or do calculus problems.

Selective colonization requires both bacterial motility and chemotaxis (the ability to change direction of movement in response to environmental cues), and higher levels of bacterial accumulation cause slower healing.

When the researchers mapped the data onto the seed plant family tree, they found that plants with the ability to regulate the timing of germination in response to environmental cues were more likely to spin off new species.

«The membranes we created, though completely synthetic, mimic several features of more complex living organisms, such as the ability to adapt their composition in response to environmental cues,» said Neal Devaraj, an assistant professor of chemistry and biochemistry at UC San Diego who headed the research team, which included scientists from the campus» BioCircuits Institute.

Her next series of studies was to show that these multiple loops and bundles of neurons form the anatomical basis for the learning of new habits in response to environmental cues.
