Sentences with phrase «same small gene»

Carter's recent experimental studies showed that the two small enzyme ancestors of these two families were encoded by opposite, complementary strands of the same small gene.

Not exact matches

Intriguingly, DNA in many of the placenta samples has the same imprinting abnormality seen in Silver - Russell, but a dampened down version of it — perhaps a smaller stretch of the gene is affected, or gene expression is less abnormal.

The genome shows that octopuses have the same small repertoire of neurotransmission genes as lower mollusks.

They discovered that the smallest breeds, like Chihuahuas, all had the same gene variant that would make them small.

Meanwhile, a second, smaller team led by Richard Fishel at the University of Vermont and Richard Kolodner at the Dana - Farber Cancer Institute in Boston was closing in on the same gene, using a more traditional strategy.

Upon sequencing the DNA, they found that DNA fragments containing mutated genes — markers of tumors — were typically smaller than healthy versions of the gene from within the same patient.

The researchers considered two possible explanations: Disease suppression might be the result of one or two additional substitutions on the same gene that buffer the harmful effect of the mutation; or suppression may be caused by numerous small substitutions throughout the genome that form an aggregate «shield.»

«People with the three gene versions believed to encourage depression had a smaller hippocampus than those with fewer or none of these gene versions, even though they had the same number of stressful life events,» says study leader Lukas Pezawas, describing the results.

They found 10 microRNAs — small pieces of RNA that regulate gene expression — that were the same in all three species.

«Because the primary Small Intestine Chip recapitulates the physical microenvironment that cells experience inside the human body, such as fluid flow and cyclic peristalsis - like stretching motions, it exhibits a genome - wide gene expression profile that comes closer to its in vivo counterpart than that of the same intestinal cells grown as 3D organoids,» said first - author Magdalena Kasendra, Ph.D., a former Postdoctoral Fellow on Ingber's team and now Principal Scientist at Emulate, Inc. in Boston.

Even though we all have the same genes, there are small variations that can influence gene activity.

Unlike typical eukaryotic organisms, Tetrahymena has two nuclei — a micronucleus that contains normal chromosomes and a macronucleus whose chromosomes are fragmented into thousands of small pieces of DNA that all encode the same ribosomal RNA gene.

Leaving aside the fact that none of these folks look like they belong in the same gene pool (and The Wire has a funny article about how only one of the actors in the film is actually Jewish), the premise has promise, since forcing the members of a dysfunctional family (and there is much «dys» here) to spend time in a small space could lead to some funny results.

First it will be necessary to formally exclude the COMMD1 gene by sequencing all of COMMD1 in a small number of affected dogs that are known to not carry the COMMD1 deletion to ensure there is not a second mutation in the same gene.

Whilst some of the lost alleles may be deleterious versions of genes, the process may at the same time increase the proportion of other, mildly deleterious alleles, in the small gene pool, and thus increase the incidence of some diseases.
