Our genome contains the genes that code for the proteins that carry out most biological functions, as well as a lot of other sequence. Some of that other sequence serves various regulatory roles, and ...

The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to researchers. Their study of the model organism Daphnia ...

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 ...

Group II introns comprise the majority of noncoding DNA in many plant chloroplast genomes and include the commonly sequenced regions trnK/matK, the rps16 intron, and the rpl16 intron. As demand ...

This is a preview. Log in through your library . Abstract The gene encoding the small subunit rRNA serves as a prominent tool for the phylogenetic analysis and classification of Bacteria and Archaea ...

Pre-mRNA splicing in a subset of human short introns is governed by a distinct mechanism involving a new splicing factor Protein-coding genes carry the blueprint for protein production. In higher ...

MicroRNAs (miRNAs) are the ∼22 nucleotide products of a two-step enzymatic maturation process facilitated by Drosha and Dicer, respectively 1. After biogenesis, the miRNA is then incorporated into the ...

Anyone who's taken basic biology should know that genes made of DNA get transcribed into messenger RNAs, which in turn get translated into the strings of amino acids, forming the proteins that do much ...

Researchers confirm that the established pre-mRNA splicing mechanism that appears in textbooks cannot work in a subset of human short introns: A novel SAP30BP–RBM17 complex-dependent splicing has been ...

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 ...

Scientists at the University of California, Davis have discovered that DNA sequences thought to be essential for gene activity can be expendable. Sequences once called junk sometimes call the shots ...
