Understanding Protein Synthesis and Genetics

What is the main function of mRNA in protein synthesis?

• To carry amino acids to the ribosome

• To carry the genetic code from DNA to the ribosome

• To form the structure of the ribosome

• To replicate DNA

What is the role of tRNA during translation?

• It copies DNA into RNA

• It brings amino acids to the ribosome

• It forms the double helix structure

• It synthesizes mRNA
