Sentences with phrase «factor genes code»

Transcription - factor genes code for proteins that regulate the activity of other genes and so affect an animal's ability to respond to its environment.

Not exact matches

The OAR proposal uses a variation of therapeutic cloning called altered nuclear transfer (ANT) in which the nucleus of a donor cell (a skin cell, for example), containing the 30,000 genes of the genetic code, is altered in such a way that it produces an epigenetic factor, a protein called nanog.

For nearly two decades, gene therapy researchers have focused on delivering a gene carrying the code to produce the deficient clotting factor in hemophilia.

One of the genes most often associated with anorexia nervosa codes for BDNF, a factor involved in neuron survival and neuroplasticity.

Environmental factors can modify DNA and lead to heritable changes in the way that genes are expressed — even though the genetic code itself is unchanged.

Another connects post-traumatic stress disorder to methylation of the gene coding for neurotrophic factor, a protein that regulates the growth of neurons in the brain.

Affected family members, the group found, had inherited one or two defective copies of ZIC3, a previously unknown gene that appears to code for a transcription factor — a protein that switches other genes on or off.

Working with cultures of respiratory tract cells, Elias's team found that the gene that codes for il - 6 is inactive unless a protein known as nf - kb (nuclear factor - kappa beta) attaches to the gene.

The gene (E2A) that codes for proteins with the properties of immunoglobulin enhancer binding factors E12 / E47 was mapped to chromosome region 19p13.2 - p 13.3, a site associated with nonrandom translocations in acute lymphoblastic leukemias.

All of these genes code for transcription factors, which are proteins that control the expression of other genes.

The gene codes for a type of protein called a transcription factor.

Naturally, every gene is not regulated by its own distinct transcription factor; otherwise, a codebook of as many as 30,000 genes would require 30,000 transcription factors — and 30,000 more genes to code for them.

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

In addition to looking at transcription factors, researchers have studied the genes that code for the enzymes responsible for building up the plant's biomass.

The genes for each transcription factor were made from different bits of DNA that code for the functional parts of proteins, such as a domain that can bind to DNA and another that provides the protein with access to the cell's nucleus.

The gene - by - hormone interaction's effect on circuit function was found only with one of two versions of the gene that codes for BDNF (brain - derived neurotrophic factor), a chemical messenger operating in the circuit.

Both genes code for proteins that function as growth factor receptors, meaning they sit on the surface of cells and, when activated, can spur the rapid cell growth that is a hallmark of cancer.

The team suspects the difference may be due to the expression of a gene that codes for a growth factor called bone morphogenetic protein 2 (Bmp2); expression was 30 % higher in the developing forelimbs of bats than it was in mice.

The branch uniting the fungi and animals is well - supported based on a number of molecular phylogenetic datasets, including the nuclear small subunit ribosomal RNA gene (Wainwright et al., 1993; Bruns et al. 1993), unique and shared sequence insertions in proteins such as elongation factor 1α (Baldauf and Palmer, 1993), entire mitochondrial genomes (Lang et al., 2002), and concatenated protein - coding genes (Steenkamp et al., 2006).

Other genetic diseases include Tay - Sachs disease (damage to the gene for the enzyme hexosaminidase A leads to an accumulation of a chemical in the brain that destroys it), sickle cell anemia (improper coding of the gene that produces hemoglobin), hemophilia (lack of a gene for a blood - clotting factor) and muscular dystrophy (caused by a defective gene on the X chromosome).
