Molecular Information Flow and Protein Processing - Transcription in Archaea and Eukarya
9 important questions on Molecular Information Flow and Protein Processing - Transcription in Archaea and Eukarya
Most important recognition sequence in archaeal and eukaryotic promoters?
Located 18-27 nucleotides upstream of transcriptional start site
Upstream of TATA box and is recognized by the archaeal transcription factor B (TFB).
Alteration in the transcript of genes
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
RNA molecule originally transcribed before the introns are removed to form the mature mRNA containing only exons
Removal of introns and joining of exons.
Macromolecular complex containing both RNA and protein that aids in RNA splicing
Processing is catalyzed by a special ribonuclease rather than by spliceosome complex that acts like introns in archaea
A process where the methylatedguanine nucleotide is added at the 5′-phosphate end of the mRNA in eukaryotes
Trimming the 3′ end of the primary transcript and adding 100–200 adenine residues, called the poly(A) tail
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
