Sentences with phrase «together on the chromosome»

Another surprise is that the nematode genes identified so far are packed much more tightly together on the chromosome than anyone had previously expected, which suggests that the nematode has many more genes in total than was previously thought.

Genes that are grouped together on chromosomes in other animals were dispersed in the octopus genome, likely as a result of transposon activity.

Not exact matches

First a chromosome is catastrophically shattered when it loses the caps on its ends, known as telomeres, that hold it together.

So team member Jaebum Kim, now at Konkuk University in Seoul, and colleagues wrote a sophisticated computer program that was able to reconstruct the original eutherian chromosomes based on what parts of the chromosomes are together today in those 19 species.

After analyzing both scans together for DNA variants associated with differences between when each patient's movement - associated symptoms first appeared and when they would have been expected based on the number of CAG repeats, MGH CHGR investigator and lead author Jong - Min Lee, PhD, identified two locations on chromosome 15 where variants were significantly associated with either early or late symptom onset.

However, some genes are close enough together on the same chromosome that they frequently do get passed along together.

As when he worked on the human genome, Venter is relying on a radical technique called shotgun sequencing: He chops up vast amounts of DNA into tiny pieces and then uses sophisticated computer analyzers to piece them back together into intelligible genes and chromosomes.

Jim (on the right), whose Y chromosome was sequenced, together with Dolly, his mother, and Binti, his sister.

Biologists and informatics experts are launching a quiet revolution aimed at building better genomes, one made possible by newer sequencing technologies, novel methods for locating sequences on chromosomes, and improved software for piecing DNA together.

Genes which lie close to one another on a chromosome are usually inherited together and are said to be linked.

The team focused on the six best - assembled genomes to put together a karyotype — organised profile — of the dinosaur ancestor for each chromosome.

Telomeres are important because they stop chromosomes from «fraying» or clumping together and «scrambling» the genetic codes they contain, performing a role similar to the plastic tips on the end of shoelaces, to which they have been likened.

This inversion prevented genes within it from recombining with corresponding genes on a sister chromosome, and so cemented around 125 adjacent genes together.

Because genes and plant regulatory networks are distinct from one another, closely coordinated genes can be widely separated from one another on chromosomes and still work together effectively and in many crop plants (maize for instance) much of the DNA does not contain genes.

They will focus on how those genes, from different parts of chromosomes, work together to determine what type of heart cells will be made, and how these mechanisms are disrupted by gene mutations that cause congenital heart defects.

The authors exploited linkage disequilibrium (the tendency of variants on the same chromosome to be inherited together) to identify, in Europeans, variants that tend to be inherited together with associated SNPs.

In his lab at UCSD now, Corbett focuses on the proteins that organize meiotic chromosomes and control meiotic recombination, the cutting and pasting together of chromosomes.

Segments of DNA that are located on the same chromosome are «linked» because they are likely to be inherited together, with the segments in closest proximity being the most likely.
