Question

Which of the following is a function of RNA polymerase?
Answer

unwind the DNA double helix during transcription

join the RNA strands after replication

add amino acids to the growing polypeptide chain during translation

separate the protein from the ribosome during termination

*unwind the DNA double helix during transcription

Answer 1

I agree with you, the answer is A. :)

Answer 2

Agree as well

Answer 3

During replication, DNA polymerase does not unwind a DNA double helix (a separate enzyme called helicase does), but during transcription, RNA polymerase does unwind (a local region of) a DNA double helix.
So yes, A is it. :p

Answer 4

Yup, it's A ^_^

Answer 5

Answer 12

Which type of RNA is called the "blueprint" for construction of a protein:
Answer

tRNA

rRNA

mRNA

all three types of RNA act as "blueprints"

*mRNA

Answer 13

The pattern for the construction of a protein is copied to the messenger RNA by transcription in the cell nucleus. Then the translation into a chain of amino acids takes place in a ribosome of the cell. The tRNAs transfer the appropriate amino acids to build the protein according to the blueprint carried by the mRNA.
You are correct when choosing mRNA, it is *messenger*RNA. :) Good Job.
