What is the role of the RNA polymerase in protein synthesis?

• RNA polymerase will unzip the DNA strand and transcribe an mRNA strand.

• RNA polymerase will transcribe the mRNA strand.

• RNA polymerase will unzip the DNA strand.

• RNA polymerase will unzip the RNA strand and transcribe an mRNA strand.

Where does protein synthesis first begin?

• In the endoplasmic reticulum.

• In the ribosomes.

• In the cytoplasm.

• In the nucleus.

What is an anti-codon, what RNA type has anti-codons?

• An anti-codon is the complementary bases to a codon of tRNA. This occurs in mRNA.

• An anti-codon is a set of 3 nucleotide bases complementary to a codon of DNA. This occurs in tRNA.

• An anti-codon is the complementary bases to a codon of mRNA. This occurs in tRNA.

• An anti-codon is a codon of mRNA.
