Latest Molecular genetics Stories
Genetic researchers have devised a new technique that lets them permanently and selectively delete genes from a cell's DNA.
Researchers at the University of California, San Diego School of Medicine have successfully targeted T lymphocytes – which play a central role in the body's immune response – with another type of white blood cell engineered to synthesize and deliver bits of non-coding RNA or microRNA (miRNA).
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.
As the Do-It-Yourself Biology (DIYbio) community has grown, so have concerns among media and policymakers about these science enthusiasts’ ability to wield DNA and manipulate life.
University of Adelaide researchers have taken a step forward in unraveling the causes of a commonly inherited intellectual disability, finding that a genetic mutation leads to a reduction in certain proteins in the brain.
