Latest Gene Stories
Chromosomes – the 46 tightly-wrapped packages of genetic material in our cells – are iconically depicted as X-shaped formations.
A molecular technique that will help the scientific community to analyze -- on a scale previously impossible -- molecules that play a critical role in regulating gene expression has been developed by a research team led by a chemist and a plant biologist at Penn State University.
The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y.
There is good evidence from studies of families and twins that genetics plays an important role in the development of alcoholism.
Using a new method to catch elusive "jumping genes" in the act, researchers have found two human proteins that are used by one type of DNA to replicate itself and move from place to place.
One of the most important processes in the life of cells is genome replication, which consists of making exact copies of the DNA in order to pass it on to their offspring when they split.
Bacteria recycle broken DNA that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome.
By using a new analysis method, researchers at Karolinska Institutet and Science for Life Laboratory (SciLifeLab) in Sweden have found close to one hundred novel human gene regions that code for proteins.
Those of us who want to learn about our ancestors — who they were, where they came from and how they mingled (or didn't) with others around them — often turn to historical records or elderly family members for answers.
Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene.
A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...
