Lecture October 7

Question 1

Transcription and translation happen at same time for:

Answer 1

Bacterial cells

Question 2

What is a monocistronic gene

Answer 2

A gene codes for a single protein in the CDS

Question 3

What is a polycistronic gene?

Answer 3

a gene that codes for
multiple proteins CDS in a single
molecule of mRNA

Question 4

What type of genes to eukaryotes have?

Answer 4

Monocistronic

Question 5

What is 5’ capping

Answer 5

Occures during transcription elongation.
5th serine is phosphorolyzed by TFIIH.
Capping factor jumps from CTD (Tail) of RNA Poly and lands on the mRNA 5’ end

Question 6

What happens when 5th and 2dn serine are phosphorolated

Answer 6

The slpicing protein can slug its way on

Question 7

What happens when 2nd serine is phosphorolated?

Answer 7

The polyA tail can be added to the mRNA

Question 8

Most prokaryotic genes are ____

Answer 8

polycistronic

Question 9

Transcription and translation occur at the same time for…

Answer 9

polycistronic genes (bacteria)
