Genes in a sentence

In many of his writings, Mayr rejected reductionism in evolutionary biology, arguing that evolutionary pressures act on the whole organism, not on single genes, and that genes can have different effects depending on the other genes present.

Protein-coding genes and RNA-coding genes are generally non-repetitive DNA. citation A bigger genome does not mean more genes, and the proportion of non-repetitive DNA decreases along with increasing genome size in higher eukaryotes.

The examples Dawkins used were genes in orchids affecting orchid bee behavior (to increase pollination), genes in rattlesnakes causing avoidance behavior in other animals, and genes in male peacocks affecting copulatory decisions of peahens.

The extended transcripts (the 'late early' transcripts) include the N and cro genes along with cII and cIII genes, and xis, int, O, P and Q genes discussed later.

The phage genes expressed in this dormant state code for proteins that repress expression of other phage genes (such as the structural and lysis genes) in order to prevent entry into the lytic cycle.

These can be coded for by master regulatory genes and either activate or deactivate the transcription of other genes; in turn, these secondary gene products can regulate the expression of still other genes in a regulatory cascade.

The condensed chromatin was also found around the differentiation-related genes, which kept the genes silent.

The research suggests that reducing intake of resistance genes is particularly effective during periods of antibiotic treatment where there is an increased risk of the retainment of genes.

These included genes relating to pigmentation, which is known to protect cells against UV light, as well as genes associated with inflammation and the immune system.

A total of 459 differentially expressed genes (DEGs) were identified, with critical structural genes like CHS, F3H, and ANS showing higher expression in purple leaves, driving anthocyanin production.

These duplicated resistance genes are often linked to "jumping genes" called transposons that can move from strain to strain.

Apart from the genes that allow the viruses to replicate, the scientists have also found genes that shut the viruses out, the statement said.

New research shows that genes respond to exterior factors and life circumstances, and as a result either turn genes on or off.

This on and off of genes is understand by the terminology of gene regulation Likewise, the metabolite or hormones are actually functional protein which produces by taking the reference from the coded information, by various genes in DNA of an organism.

And we try to put together the patterns of which genes did and didn't affect lifespan, especially which genes might extend lifespan,” he said.

Rhizobia silence those genes with small RNAs, short nucleotide sequences that dismantle the genetic codes in the nodule-suppressing soybean genes.

However, the researchers took a set of regulatory genes, called a GAL regulon that normally processes galactose and replaced some of the genes with those that become activated by and direct the breakdown of xylose.

Some genes offer traits that allow certain animals or plants to thrive in their environment, so these genes will be passed along.

Activated p53 binds DNA and activates expression of several genes including microRNA miR-34a, citation WAF1/CIP1 encoding for p21 and hundreds of other down-stream genes.

Although co-expression does not necessarily indicate co-regulation, methylation of bidirectional promoter regions has been shown to downregulate both genes, and demethylation to upregulate both genes. citation There are exceptions to this, however.
