This narrated animation illustrates the process of protein synthesis, starting with chromosomal DNA inside the cell's nucleus. A gene is transcribed into messenger RNA, which leaves the nucleus ...

It has long been accepted that a gene's protein-coding information is contained in only one of its two DNA strands. But in 22 February Nature, Victor Corces and co-workers at the Department of Biology ...

During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins ...

From DNA to Epigenetics: Historical Breakthroughs The word “genetic” has an intuitive meaning: something that lies in DNA. A change in the genetic code can result in a change in the organism’s ...

Telomeres are repetitive sequences of DNA that can be found at the ends of chromosomes, where they form a kind of protective cap. Telomeres get shorter every time a cell divides, and they are thought ...
