Definition
transfer RNA (2% of total RNA) transfers amino acid to a growing peptide. |
|
|
Term
|
Definition
messenger RNA (1% total RNA) carries genetic code from DNA for synthesis of proteins. |
|
|
Term
|
Definition
segment of DNA molecule that contains information for building specific proteins. |
|
|
Term
|
Definition
upstream promoter, which may extend over as many as 200 bp farther upstream. contains signs to turn a gene on or off. transcription factors binds in this region to promote or inhibit the transcription. regulates how much RNA is manufactured. |
|
|
Term

Definition
contain information to stop transcription. |
|
|
Term
|
Definition
Basal promoter of 7 bases. bound by large complex of some 50 different proteins. Transcription Factor IID which is a complex of TATA-binding proteins & other protein factors which bind to TBP. This is where RNA polymerase II binds. |

Term
What nucleotide is used to make a 5' cap for the mRNA? |
|
Definition
|
|
Term
What does the 5' cap do for the mRNA? |
|
Definition
It protects the mRNA from degradation by enzymes that degrade from the 5' region. |
|
|
Term
|
Definition
splices the remaining exons back together after removing the introns. |
|
|
Term
|
Definition
A nucleotides at the 3' end of the mRNA. completes the RNA molecule which is now ready for export to the cytosol. remainder of the transcript is degraded. |
|
|
Term
|
Definition
the process in which the introns of precursor messenger RNA are removed and the remaining exons of the pre-mRNA are stitched together. |
|
|
Term
|
Definition
