Question 7

DNA plays what role in protein synthesis?

Accepted Answer

DNA give us the directions on how to make a protein amino acid by amino acid.

Answer

No role.

Answer

Determines the base pairing rules.

Answer

DNA is the police force to make sure everything is orderly.

Question 8

What role does mRNA play in protein synthesis?

Accepted Answer

Messenger RNA – sends the message from DNA on how to make the protein.

Answer

mRNA transfers amino acids to the ribosomes to make the protein strand.

Answer

Messenger RNA – sends the message to the DNA on how to make protein.

Answer

mRNA doesn't have a specific purpose in translation/protein synthesis.

Question 9

What role does tRNA play in protein synthesis?

Accepted Answer

tRNA transfers the correct amino acid to the ribosome for protein assembly.

Answer

Separates the large and small ribosomal subunits.

Answer

tRNA transcribes the DNA code to mRNA.

Answer

Attaches to the rRNA.
