Question

Which statement names a difference between DNA and RNA?

1) RNA has thymine.
2) They have different sugars.
3) RNA contains lipids.
4) Most types of RNA are double stranded.

Answer 1

DNA and RNA have several key differences, including their sugars and structure. DNA contains deoxyribose and is double-stranded, while RNA contains ribose and is single-stranded.

Step-by-step explanation:

DNA and RNA are both types of nucleic acids that play important roles in genetic information storage and protein synthesis. However, they have several key differences. One of the main differences is in their sugars:

1. DNA contains deoxyribose while RNA contains ribose. This difference in sugar composition is important for the structure and function of these molecules.

Another significant difference is:

1. DNA is double stranded while RNA is single stranded. This means that DNA consists of two complementary strands that are connected by hydrogen bonds, while RNA consists of a single stranded chain of nucleotides.

These differences in structure and composition contribute to the different functions and roles that DNA and RNA play in the cell.
