Q. 17.99 - An Introduction to General, Organic, and Biological Chemistry

Question

What is similar about the primary structure of RNA and DNA?

Step-by-Step Solution

Answer

 The Similarity between DNA and RNA is that  both are unbranched nucleotide chains linked by phosphodiester connections between alternating sugar and phosphate groups.

Step 1 : Given information

We need to find similarity about the primary structure of RNA and DNA

Step 2 : Simplify

Nitrogenous bases, pentose sugar, and the phosphate backbone are all referred to as nucleotides.
DNA and RNA each have four nitrogenous bases, three of which are shared: cysteine, adenine, and guanine.
DNA and RNA are both unbranched nucleotide chains linked by phosphodiester connections between alternating sugar and phosphate groups, with bases extending out from each sugar.
