RNAkäsittelyn
RNAkäsittelyn, often translated as RNA processing, refers to the series of modifications that occur to an RNA molecule after it has been transcribed from a DNA template. These modifications are crucial for the maturation and proper function of RNA, particularly messenger RNA (mRNA), in eukaryotic cells. The primary stages of RNA processing in eukaryotes include capping, splicing, and polyadenylation.
The 5' cap, a modified guanine nucleotide, is added to the beginning of the nascent mRNA molecule
Splicing involves the removal of non-coding sequences called introns from the pre-mRNA and the joining together
Polyadenylation is the addition of a tail of adenine nucleotides, known as the poly-A tail, to the
In prokaryotes, RNA processing is generally minimal, as transcription and translation occur simultaneously and there are
