In E. coli, 5S rRNA is cleaved out of the pre-rRNA operon by: a. RNase III b. RNase E Correct Answer-RNase E The 5' cap: a. Does not play a role in translation b. Interacts with the poly A tail during transport out of the nucleus c. Protects the mRNA from 5' exonucleases d. Is acetylated e. Is sometimes found on E. coli mRNA Correct Answer-Protects the mRNA from 5' exonucleases The addition of the poly A tail: a. Occurs during the elongation phase of transcription b. Occurs during...

Pribnow box correct answers -interacts with a specific component of sigma part of RNA polymerase to line it up on DNA -located 10 bases before the start of transcription -consensus TATAAT Sigma factor correct answers -key to allowing RNA polymerase bind to promoter sequence -more than one sigma factor -turn on/off whole suits of genes -closer to particular sequence in promoter (consensus), the stronger the promoter -recognize Pribnow box and -35 region -35 region correct answers ~35 ...

Information in DNA - ️️same as mRNA, transcription termination and initiation information, splicing information catalytic domain - ️️protein domain in enzyme-linked receptors, activated by a conformational change induced by the ligand-binding domain, inhibits host cell protein synthesis and interacts with substrate to cause enzyme reaction tRNA - ️️An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and r...
