Five Prime Cap
In molecular biology, the 5′ cap is a specially altered nucleotide on the 5′ end of precursor messenger RNA and some other primary RNA transcripts as found in eukaryotes. The process of 5′ capping is vital to creating mature messenger RNA, which is then able to undergo translation. Capping ensures the messenger RNA's stability while it undergoes translation in the process of protein synthesis, and is a highly regulated process that occurs in the cell nucleus. Because this only occurs in the nucleus, mitochondrial and chloroplast mRNA are not capped.

Famous quotes containing the words prime and/or cap:
“In time, after a dozen years of centering their lives around the games boys play with one another, the boys’ bodies change and that changes everything else. But the memories are not erased of that safest time in the lives of men, when their prime concern was playing games with guys who just wanted to be their friendly competitors. Life never again gets so simple.”
—Frank Pittman (20th century)
“‘I have cap and bells,’ he pondered,
‘I will send them to her and die’;
And when the morning whitened
He left them where she went by.”
—William Butler Yeats (1865–1939)
