(Phys.org)—The majority of the human genome is located within the nucleus. However, there is a small but important portion of DNA located within the mitochondria. This mitochondrial DNA (mtDNA) has received much attention ...
Before DNA can be transcribed into RNA, an early step in turning the genetic template into protein, the nucleus must first assemble a molecular machine called the pre-initiation complex (PIC), capable of unzipping the double ...

(Phys.org) —A team of researchers working at the University of Tokyo has at long last uncovered the mysterious mechanism by which gender is determined in the silkworm (and other lepidoterans). In their paper published in ...
DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding DNA determines the ...
