Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing production of certain messenger RNAs and appear to help cells respond to ...

In the genome, genes that code for protein are often divided into sections called exons, which are separated by spacers called introns. When a region of DNA is transcribed into messenger RNA (mRNA) or ...

The completed sequencing of entire bacterial genomes and recent advances in genomics has allowed the identification of many genes. While several genes have been characterized, the function of the ...
