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 ...

Exons are coding sections of an RNA transcript, or the DNA encoding it, that are translated into protein. Exons can be separated by intervening sections of DNA that do not code for proteins, known as ...

Researchers have shown for the first time that non-coding parts of genes called introns can copy themselves and move around the genome. Nevertheless, these DNA sequences remain mysterious. Scientific ...

Researchers have developed a technique to capture rapidly evolving genomic regions to understand evolutionary relationships among closely related species. Typically, studies use protein-coding genes, ...

One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code ...

Each mRNA transcript contains coding regions, known as exons, and noncoding regions, known as introns. They also include sites that act as signals for where splicing should occur, allowing the cell to ...

WHEN WE HUMANS got a first glimpse of our genome, we had good reason to question our biological complexity. Many scientists predicted we would possess some 100,000-plus genes, but sequencers finally ...

Researchers at Baylor College of Medicine and collaborating institutions have discovered that a protein called hnRNPM helps protect the integrity of the process cells use to make proteins. The protein ...

The Supreme Court ruled today that Myriad Genetics doesn't own your DNA after all. Myriad holds patents on the BRCA1 and BRCA2 genes, which are linked to an increased risk of breast and ovarian cancer ...
