Homework Answers
Correct answer: RNA
RNA polymerase synthesis RNA from DNA template strand. Transcription is the name of process in which DNA is converted into RNA with the help of enzyme RNA polymerase. After transcription, translation occurs, Protein is synthesized from mRNA.

13. Why are ribonucleoside triphosphates the monomers required for RNA synthesis rather than ribonucleoside monophosphates? A. Only ribonucleoside triphosphates contain the sugar ribose. B. Ribonucleoside triphosphates have low potential energy, making the polymerization reaction endergonic. C. Ribonucleoside triphosphates have high potential energy, making the polymerization reaction exergonic. D. Ribonucleoside monophosphates cannot form complementary base pairs with the DNA template. E. Ribonucleoside triphosphates are not used, rather all use deoxyriboside triphosphates. 14. How is a mutation in a bacterial cell that...
