In some genes, not all of the DNA sequence is used to make protein. Introns are noncoding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is ...

The database is searchable by Blast, GenBank attributes and elements that we have annotated within introns, and gives graphical views of gene structure and elements such as alternative coding ...

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 ...

However, the mechanisms that drive this transition are poorly understood. In a study published in mBio, a research team identified alternative splicing—the selective inclusion or excision of introns ...

which lies both between genes and within the introns, consists of highly repeated DNA sequences. Further, most of these ...

Findings on Fugu gene splicing could help scientists develop pufferfish transgenes for mammalian cells, say researchers at Massachusetts Institute of Technology. The Fugu genome contains all the ...

Non-coding parts of a gene, called introns, are typically removed as a gene's DNA is transcribed into an RNA version in a process called splicing. Cancer cells can interfere with splicing to ...
