When genes were first discovered, the canonical view was that each gene encodes a unique protein. However, biologists later found that segments of genes can be combined in different ways, giving rise to many different proteins.

(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 ...
A bacterial protein helps to stop transcription—the process of making RNA copies of DNA to carry out the functions of the cell—by causing the cellular machinery that transcribes the DNA to pause at the appropriate spots ...
