Protein Synthesis Quiz

What is the central dogma of genetics?

• Proteins are synthesized directly from DNA.

• DNA is transcribed into RNA, which is then translated into proteins.

• RNA is converted into DNA, which then forms proteins.

• DNA is converted directly into proteins.

Which type of RNA carries the genetic instructions from the nucleus to the ribosome?

• sRNA

• tRNA

• rRNA

• mRNA

What is the primary role of tRNA in protein synthesis?

• To unzip DNA strands.

• To carry genetic information from DNA.

• To form the structure of ribosomes.

• To transfer amino acids to the ribosome.

During transcription, which base pairs with adenine in RNA?
