Sentences with phrase «single nucleotide difference»

By SNP analysis, single nucleotide differences between the sequences of 22Rv1 - associated XMRV and XMRV genomes detected in prostate cancer tissues [VP35, VP42, and VP62 (2006)-RSB-(red lollipops) are corrected by the deep sequencing coverage data (black lollipops).

Not exact matches

Single - nucleotide polymorphisms (SNPs — pronounced «snips») are the most common type of human genetic variation; each one represents a small difference in a nucleotide — the building blocks of our DNA.

All three teams found sections of DNA — haplotypes — that differed and ultimately pinpointed a single - letter difference that changed the amino - acid content of complement factor H. HapMap researchers say that refining the map further will speed up such discoveries, and they plan to release a new version this month that will include 4 million single - nucleotide variants.

Furthermore, the analysis of data on single - nucleotide polymorphisms, the main cause of difference between human beings, allows the prediction of phenotypic effects of a particular genetic variation.

Samani and his colleagues analyzed more than 500,000 genetic variations (naturally occurring, single - nucleotide differences) spanning the genome in blood cells collected from almost 3,000 people.

HapMap is a directory of «single nucleotide polymorphisms,» or SNPs, places in the genome where differences between individuals (in the form of single chemical letters) appear in the DNA code.

Humans and chimps each have somewhere between 20,000 and 30,000 genes, so there are likely to be nucleotide differences in every single gene.

Then they checked blood samples against half a million known variations in DNA sequences, or single - nucleotide polymorphisms, which recently were identified by the International HapMap Project that looked for differences in the genomes of people from many populations.

Looking for single nucleotide polymorphisms (SNPs) or subtle variations in the DNA sequence, they found differences in AHR2, which plays an important role in mediating toxicity in early life stages.

SMN1 and SMN2 are nearly identical, he said, and the only consistent difference between them is a single nucleotide variation at the start of exon 7.

They do this by aiming for little genetic differences in DNA called single nucleotide polymorphisms, or «SNPs» (pronounced «snips»).
