Question
Chapter 30, Problem 25P
Interpretation Introduction
Interpretation:
The biological function of DNA and RNA should be determined. The features of RNA structure and chemistry that make it so useful or important should be determined.
Concept introduction:
DNA synthesis can be defined as the process by which the deoxynucleic acids such as adenine, thymine, cytosine, and guanine are associated together to form DNA.
RNA synthesis (transcription) is the synthesis of an RNA molecule from the nucleotide’s adenine, cytosine, guanine, or uracil. The

A single-stranded chain of alternating phosphate and ribose units with the bases Adenine, Guanine, Cytosine, and Thymine bonded to the ribose. b). RNA molecules are involved in protein synthesis and sometimes in the transmission of genetic information. c). The helix geometry of RNA is of A-Form. RNA strands are continually made, broken down and reused. RNA is more resistant to damage by Ultra-violet rays. d). Ribose sugar is more reactive because of C-OH (hydroxyl) bonds.
