Q. 17.100 - An Introduction to General, Organic, and Biological Chemistry

Question

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

Step-by-Step Solution

Answer

The difference in the primary structure of RNA and DNA is that  RNA contains the sugar ribose, whereas DNA has the sugar deoxyribose

Step 1 : Given information

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

Step 2 : Simplify

DNA and RNA are distinguished by two characteristics:
(a) RNA contains the sugar ribose, whereas DNA has the sugar deoxyribose, which is slightly different (a type of ribose that lacks one oxygen atom)
(b) The nucleobase uracil is found in RNA, whereas thymine is found in DNA.
