Molecular Biology News and Research

RSS

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Higher doses of rifampin kill more TB bacteria in sputum without increasing adverse effects

Higher daily doses of rifampin, a cornerstone of tuberculosis treatment, killed more TB bacteria in sputum cultures, and the higher doses did so without increasing the adverse effects of treatment, according to a randomized controlled trial published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Synthetic gene reveals potential therapeutic target for rare, inherited disease

DNA Repair is essential for a healthy organism. In every day of our lives, tens of thousands of damages occur in the genetic material of our cells. Hence, it is not surprising that a broad variety of repair mechanisms developed in the course of evolution that enables cells to quickly react and patch up the affected DNA strands.

UCLA researchers have blueprint of telomerase that plays major role in cancer, aging

Cancer, aging-related diseases and other illnesses are closely tied to an important enzyme called "telomerase." UCLA researchers report in the journal Cell the deepest scientific understanding yet of this once-mysterious enzyme, whose catalytic core -- where most of its activity occurs -- can now be seen in near atomic resolution.
