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 ...

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 ...

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 ...
