Sentences with phrase «nucleotide differences in»

All reads covering a given position yielded the same (corrected) nucleotide, indicating that previous nucleotide differences in published genomes [1](red lollipops) are due to sequencing error.

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.

Not exact matches

«The mean difference in leukocyte telomere length between the most active and least active subjects was 200 nucleotides (chemical structural units of DNA and RNA), which means that the most active subjects had telomeres the same length as sedentary individuals up to 10 years younger, on average.»

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.

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.

One might assume that the differences between chimp and human genes boil down to those sorts of typographical errors: one nucleotide being swapped for a different one and altering the gene it sits in.

When the chimp and human genomes are compared, some of the clearest cases of nucleotide differences are found in genes coding for transcription factors.

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.

In genomes involving billions of nucleotides, a tiny 2 percent difference translates into tens of millions of ACGT differences.

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.

Penn Vet researchers showed that differences in the order of nucleotides — not the amino acids — governed the distinct functions of two forms of actin.

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.

The tests look for differences in the DNA nucleotides adenosine, thymine, guanine, and cytosine (A, T, G, and C — the letters of the genetic code) between one person and another, or between one group of people and another group.

Scott D. Collins, Ph.D., University of Maine, Orono $ 850,000 (2 years) «High - speed Nanopore Gene Sequencing» Skilled in silicon fabrication methods, this group will try to fabricate a nanopore with tiny electrodes and built - in circuits that will be used in experiments that attempt to measure differences in the electron tunneling of individual nucleotides in DNA molecules.

It will then test the device to see if it is possible to distinguish between the four types of nucleotides based on differences in a phenomenon called electron tunneling.

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

The difference in nucleotides between the two ends was calculated; a negative value indicates the 5 ′ end reported by Clowney et al. is upstream of the one reported here, by Cufflinks [33].

The difference in nucleotides between the two ends was calculated; a negative value indicates the 5 ′ end reported by nanoCAGE is upstream of the one reported by Cufflinks.

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).
