Protein Synthesis Review

How is RNA structurally different from DNA?

• RNA is double-stranded, while DNA is single-stranded.

• RNA has deoxyribose sugars, while DNA has ribose sugars.

• RNA is single-stranded, while DNA is double-stranded.

• RNA uses thymine instead of uracil.

What type of sugar does RNA contain?

• Glucose

• Deoxyribose

• Ribose

• Fructose

Which base does RNA use instead of thymine found in DNA?

• Cytosine

• Guanine

• Adenine

• Uracil

What is the role of Messenger RNA (mRNA) in the cell?

• Carries amino acids to form protein chains

• Makes up ribosomes

• Carries copies of the DNA sequence outside of the nucleus

• Is involved in the replication of DNA

What does Transfer RNA (tRNA) do?

• Carries copies of the DNA sequence outside of the nucleus

• Makes up ribosomes

• Carries amino acids to form protein chains

• Transcribes DNA into RNA

What is the function of Ribosomal RNA (rRNA) in the cell?

• Carries amino acids to form protein chains

• Makes up ribosomes

• Carries copies of the DNA sequence outside of the nucleus

• Is involved in the replication of DNA

What are amino acids considered in the context of proteins?

• Energy sources for the cell

• Building blocks of proteins

• Waste products of protein synthesis

• Enzymes that help in DNA replication

What is the job of mRNA?

• To create proteins directly from DNA

• To make a copy of the DNA sequence

• To replace the original genetic blueprint

• To assist in the replication of DNA

What is the process of making an mRNA copy from a DNA template called?

• Translation

• Replication

• Transcription

• Mutation

What enzyme is responsible for unwinding a small section of the DNA strand during transcription?

• DNA ligase

• Helicase
