Sentences with phrase «different gene complexes»

Ho - mo - logous or - gans are now known to be produced by totally different gene complexes in the different species.

Not exact matches

These people interbred at the edges of their separate populations, keeping the entire complex network interconnected — and so giving the ancient Kostenki man genes from three different groups.

Complex traits like the ones in the study are each influenced by many different genes, while at the same time, several different traits can be affected by the same genes.

The nonredundant protein sets of flies and worms are similar in size and are only twice that of yeast, but different gene families are expanded in each genome, and the multidomain proteins and signaling pathways of the fly and worm are far more complex than those of yeast.

And determining treatment strategies will be no less complex: Last summer, for example, a team of scientists linked 124 different genes to resistance to four leukemia drugs.

The process by which bacteria make cellulose and secrete it to build biofilms is already quite complex, regulated by more than a dozen different genes working together.

Women prefer the smell of T - shirts worn by men whose major histocompatability complex genes — which encode the proteins that make up an important part of our immune system — are different from their own, and vice versa.

The genetic causes of bipolar disorder are highly complex and likely involve many different genes, said Carrie Bearden, a senior author of the study and an associate professor of psychiatry and psychology at the UCLA Semel Institute for Neuroscience and Human Behavior.

This information provides clues as to when different genes are most important during the complex process of colonizing a living organism.

The collection of proteins, called a chromatin remodeling complex, is known as SWI / SNF; its components are encoded by different genes, among them ARID2, PBRM1, and BRD7.

But efforts to construct large - scale genetic circuits in mammalian cells have largely failed: For complex circuits to work, the individual components — the turning on and off of different genes — must happen consistently.

Retinas recovering from hypoxia also showed distinct patterns of gene expression that were different from both normoxic control retinas and hypoxic retinas, indicating that hypoxia initiates a complex pattern of gene expression.

He studies the evolution of genomes and was the first to show a surprising amount of horizontal gene transfer (transmission of DNA between different genomes) in fungi, challenging our notion of how complex traits evolve within species.

The genomic DNA of complex organisms is wrapped around nucleosomes and packaged into various conformations that regulate the access of different gene regulatory factors to their target sites.

Biologists have built models of molecular interaction networks that represent the complex relationships between thousands of different genes.

Scientists stitched together the complex genome of the California two - spot octopus, and analyzed 12 different tissues in search of the genes that allow these unique cephalopods to change skin color and control eight arms independently.

We show that most genes encoding olfactory and vomeronasal receptors have complex, multi-exonic structures that generate different isoforms.

These studies demonstrate that the two important protein complexes, condensin and cohesin, are both essential for the assembly of the functional genome architecture, but their roles in the 3D genome organization (gene contacts and topological domain organization) are significantly different.

Computer simulations by Liu et al. [43], Wang et al. [41], and Sundquist et al. [47] have indicated that pyrosequencing tags from different regions of the gene will vary in their utility for the distinct tasks of revealing microbial diversity and performing taxonomic classification, both of which contribute to making informative comparisons between complex microbial communities.

Chromosomes come in different lengths and can have 100,000 genes or more in complex organisms.
