Studying the effects of this decrease can show the physiological role of the gene product.

MSS announces a protocol for finding obesity gene

Some diseases are caused by a defective gene.

Oncogenes can be activated by mutation (changes in gene structure) or by gene amplification (production of many copies of a gene).

If the activity of the gene was restored, the frequency of emitted sounds also was restored.

In humans the disruption of the normal gene does not cause the disease.

It also plays a role in the analysis of gene and protein expression and regulation.

It is a hereditary condition that is results from the combination of two parents carrying the gene.

In transcription, the codons of a gene are copied into messenger RNA by RNA polymerase.

It then copies the gene sequence into a messenger RNA transcript until it reaches a region of DNA called the terminator, where it halts and detaches from the DNA.

Only those cells losing this remaining functional allele of the BRCA1 or BRCA2 gene will become tumors.

When mutations occur, they can either have no effect, alter the product of a gene, or prevent the gene from functioning.

When the activity of the gene was artificially reduced in the animals, they screamed less when separated from mother.

The frequency of one particular allele will become more or less prevalent relative to other forms of that gene.

Gena gets very tired of playing chess against himself and decides to find himself some friends to play with.

Then there are differences that result simply from a broken gene, which is not a variant but simply a mistake.

Animals in which a human copy of the gene was introduced peeped more actively and at a lower frequency than normal mice.

The cause of most HDL diseases is unknown, but those with known causes are due to mutations in the prion protein gene (HDL1), the junctophilin 3 gene (HDL2), a recessively inherited HTT gene (HDL3 only found in one family and poorly understood), and the gene encoding the TATA box binding protein (HDL4 SCA17).

When there is a reason to be distrustful, such as experiencing betrayal, differing reactions are associated with oxytocin receptor gene (OXTR) differences.

Social Security directs a research to find the gene for obesity in children and young people it is supported by specialists from the IPN

In both organisms, if an extra copy of SIR2 is added by genetic intervention, the life span is extended. Conversely, if the SIR2 gene is deleted, the life span is shortened.

For example, the human eye uses four genes to make structures that sense light three for colour vision and one for night vision all four are descended from a single ancestral gene.

Scientists ascertained that in members of the family the activity of the Foxp2 gene had been disrupted, though the manner in which it performs its function remained unknown.

The normal cells of women carrying the BRCA1 or BRCA2 mutations can still recombine, because they retain one functional allele or alternative form of the gene.

And its tight control of the use of its patents has inhibited the development by others of better and more accurate tests for the presence of the gene.

Therefore, we suggest that PARP inhibitors might be more useful in the prophylactic treatment of women carrying the gene responsible for this form of inherited breast cancer.

Furthermore, these variants circulate partially bound to a protein (growth hormone binding protein, GHBP), which is the truncated part of the growth hormone receptor, and an acid labile subunit (ALS).

A person with Tourette's has about a 50 chance of passing the gene(s) to one of his or her children, but Tourette's is a condition of variable expression and incomplete penetrance.

Much attention was devoted to its report that each of these violent individuals also carried a mutation in the gene coding for the enzyme monoamine oxidase (MAOA).

Thus far, no leadership gene has been identified, and studies of identical and fraternal male twins find that only a third of their difference in occupying formal leadership roles can be explained by genetic factors.

For example, if you are a woman with a single bad copy of the breast cancer 1 gene, you have a 70 chance of getting breast cancer by the time you are 60 years old.

But if we take that into account, should we not also take into consideration the life of the child who the parents would have had, if they had been able to use prenatal diagnosis and be sure of having a child who does not carry the gene for the disease?

Now, some people who think they're right handed are genetically left handed. OK. I'm just saying that, if you think, oh, I don't carry a left handed gene so therefore my, you know, children won't be at risk of schizophrenia. You might. OK?
