Central Dogma of Biology Quiz

Why is it unnecessary for all cells to produce every protein encoded by the genome?

• Because each cell type has a unique function and requires specific proteins.

• Because the genome cannot encode for all proteins simultaneously.

• Because producing all proteins would consume too much energy.

• Because not all proteins are functional in every cell type.

What is the primary role of RNA polymerase during transcription?

• To replicate DNA strands.

• To produce a primary RNA transcript from DNA.

• To translate RNA into proteins.

• To modify RNA into its final form.

Which of the following is NOT a difference between DNA and RNA?

• DNA is more stable than RNA.

• DNA uses uracil, while RNA uses thymine.

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

• DNA contains deoxyribose sugar, while RNA contains ribose sugar.

What is the role of ribosomes in the translation process?

• To transcribe DNA into RNA.

• To process RNA into its mature form.

• To read mRNA and synthesize proteins.

• To transport proteins to their destination.
