8. contains the sugar deoxyribose

9. contains the sugar ribose

10. contains the base adenine

Answer 1

Correct choices: 1, 2, 4, 5, 7, 9, 10.

Answer 2

Statements that are true as regards RNA here are;

• contains the base guanine

• contains the base uracil

• contains the base cytosine

• is a single strand

• has a phosphate group

• contains the sugar ribose

• contains the base adenine

• Ribonucleic acid (RNA) can be regarded as a biological macromolecule which helps in  the conversion of  the genetic information of DNA and turn it into proteins.

• Ribonucleic acid has a  molecule that can be compared with that of  DNA.  RNA is single-stranded, it has a backbone which is composed of  alternating sugar known as (ribose) as well as phosphate groups.

• RNA has bases such as uracil, cytosine , adenine and guanine.

Therefore, options 1, 2, 4, 5, 7, 9, 10 are correct, because RNA contains ribose sugar.
