Question

question 4 of 15 which of the following structures contributes to dnas ability to function as a template for the production of new dna or mrna molecules? a. presence of phosphate groups in the backbone of the molecule b. complementary base pairing between nitrogenous bases (a, t, c, g) c. location of covalent bonds between the nitrogenous bases d. orientation of deoxyribose sugar next to phosphate groups

Explanation:

DNA functions as a template due to complementary base - pairing rules (A - T and C - G). This allows for accurate replication of DNA and transcription to mRNA. Phosphate groups in the backbone provide structural support but not the template - forming ability. Covalent bonds are not between nitrogenous bases in the way that contributes to templating. The orientation of deoxyribose sugar and phosphate groups is part of the backbone structure and not related to templating.

Answer:

B. Complementary base pairing between nitrogenous bases (A, T, C, G)
