1. What is the primary role of mRNA in protein synthesis?
Carrying amino acids to the ribosome
Serving as the template for transcription
Carrying genetic information from DNA to the ribosome
Forming the structural component of ribosomes
2. Which enzyme is responsible for synthesizing mRNA during transcription?
DNA polymerase
RNA primase
RNA polymerase
Helicase
3. During transcription, the DNA sequence is used as a template to create a complementary molecule.
4. The process of converting the genetic information from mRNA into a sequence of amino acids is called .
5. A sequence of three nucleotides on an mRNA molecule that codes for a specific amino acid is known as a .
6. Transcription occurs in the cytoplasm of eukaryotic cells.
