Transcription
The process by which the message from DNA is written down into RNA
mRNA (messenger RNA)
The form of RNA which is created as a blueprint from DNA; carries instructions for making a protein
Uracil (U)
The base found only in RNA (replaces thymine in DNA)
Nucleus
The location where transcription takes place
RNA editing
A process that takes place before the mRNA is sent to the ribosome; some RNA bases are removed in order to create a final draft of the mRNA
Introns
The sections of RNA removed from the final draft of mRNA that remain in the nucleus
Exons
The sections of RNA that make up the final draft of mRNA which is sent out of the nucleus to the ribosome
RNA polymerase
The main enzyme that transcribes DNA into mRNA
One
Number of strands RNA is made of
5' to 3'
The direction mRNA is synthesized
DNA 3' ATG CGT TAG 5' transcribes to
5' UAC GCA AUC 3'
rho protein
RNA binding protein responsible for terminating transcription
5' cap
a methylated guanine nucleotide added to the 5' end of eukaryotic mRNA
Poly-A tail
Prevents mRNA from being degraded in cytoplasm
100-250 A's at 3' end
spliceosome
complex of enzymes that serves to splice out the introns of a pre-mRNA transcript
SNRP
Small nuclear ribonuclear peptide
