Lost in translation: Researchers discover translator gene may play a role in disease

August 12, 2019 dna 0
A molecule called tRNA is an essential component of the human genome that acts as a translator. When researchers and clinicians investigate the genome’s relation to disease, they have traditionally focused on mutations in the code for proteins. But now researchers have shown that the genes encoding tRNAs can also have mutations that cause the code to be misread, and in greater numbers than previously thought.

A simpler way to choose the sex of offspring by separating X and Y sperm

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study. The study was performed in mice, but the technique is likely to be widely applicable to other mammals as well.
