Within multi-exon genes, after introns are removed, the exons must be spliced back together. Splice-enhancer domains (exon sequences near the intron–exon boundary) help to ensure that this happens ...

PCR amplification was performed in a total volume of 10 μl, containing 1 μl cDNA, 1 μl 10 × ExTaq buffer (Takara Bio, Inc., Shiga, Japan), 0.25 U ExTaq polymerase (Takara Bio, Inc.), 500 nM each ...

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 ...

Pre-mRNA splicing in a subset of human short introns is governed by a distinct mechanism involving a new splicing factor, new research finds. The interrupted non-coding regions in pre-mRNAs, termed ...

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 ...

Feasibility of consensus molecular subtype classification of colorectal cancer using preoperative biopsy specimens: A prospective pilot study.

While working on a COVID-19-related project during the lockdown, Kärt Tomberg, PhD, found herself thinking about introns. She was part of a team working on the spike protein used in vaccines. Her task ...
