DNA and Protein Synthesis Quiz

What is the primary function of DNA in living organisms?

• To provide structural support to cells

• To store and transmit genetic information

• To catalyze biochemical reactions

• To transport molecules across cell membranes

During transcription, what is the role of RNA polymerase?

• To synthesize a complementary RNA strand from a DNA template

• To unwind the DNA double helix

• To add a poly-A tail to mRNA

• To splice exons together

Which strand of DNA serves as the template for RNA synthesis?

• Both strands

• Neither strand

• The coding strand

• The non-coding strand

What is the purpose of adding a 5' GTP cap to mRNA?

• To initiate DNA replication

• To protect mRNA from degradation

• To convert mRNA into protein

• To splice introns

How does alternative splicing benefit an organism?

• It reduces the energy cost of protein synthesis

• It enhances the stability of DNA

• It allows for the production of multiple proteins from a single gene

• It increases the rate of transcription
