Question

During the process of transcription, after binding to a promoter, RNA polymerase catalyses and makes the bases in the template strand of DNA available for base pairing, with the bases of:

• A. Deoxyribonucleotide triphosphate
• B. Deoxyribonucleoside triphosphate
• C. Ribonucleotide triphosphate
• D. Ribonucleoside triphosphate

Hint:

Transcription uses ribonucleotide triphosphates as substrates for RNA synthesis.

Answer 1

The Correct Option is C

During transcription, RNA polymerase synthesizes RNA by pairing ribonucleotide triphosphates (ATP, GTP, CTP, UTP) with the DNA template strand. These ribonucleotides provide both the base and the energy (via phosphate groups) for RNA chain elongation.
