In molecular biology, the five-prime cap (5′ cap) is a specially altered nucleotide on the 5′ end of some primary transcripts such as precursor messenger RNA.This process, known as mRNA capping, is highly regulated and vital in the creation of stable and mature messenger RNA able to undergo translation during protein synthesis.

There are three different COVID vaccines to choose from this season: two mRNA vaccines from Pfizer and Moderna, and a protein-based vaccine from Novavax. These vaccines replace the previous COVID ...
The U.S. Centers for Disease Control and Prevention on Friday expanded availability of COVID-19 booster shots to all American adults, hoping to preserve vaccine protection against the fast ...
“The Moderna vaccine is a very similar vaccine to the Pfizer vaccine, so I would anticipate an approval for that could follow shortly,” said Dr. Christina Rostad, an assistant professor of ...
The NAD+ 5' cap has been observed in bacteria, [3] contrary to the long-held belief that prokaryotes lacked 5'-capped RNA, [4] as well as on the 5' cap of eukaryotic mRNA, [5] in place of the m7G cap. This modification also potentially allows for selective degradation of RNA]within prokaryotes as different pathways are involved in the ...
The 5′ untranslated region (also known as 5′ UTR, leader sequence, transcript leader, or leader RNA) is the region of a messenger RNA (mRNA) that is directly upstream from the initiation codon. This region is important for the regulation of translation of a transcript by differing mechanisms in viruses , prokaryotes and eukaryotes .
It's what officials predicted: An uptick beginning around Thanksgiving as the weather gets cold and more people gather indoors.
