DNA and RNA are two types of
A
carbohydrates.
B
nucleic acids.
C
lipids.
D
proteins.
Explanation: 

Detailed explanation-1: -The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.

Detailed explanation-2: -Nucleic acids are molecules made up of nucleotides that direct cellular activities such as cell division and protein synthesis. Each nucleotide is made up of a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acids: DNA and RNA.

Detailed explanation-3: -RNA is called nucleic acids because the phosphate group attached to it is acidic in nature. The phosphate group is negatively charged and it donates protons in solution which is an ability possessed by all acids. The phosphate groups are similar to phosphoric acid.

Detailed explanation-4: -Nucleic acids are long chains of monomers (nucleotides) that function as storage molecules in a cell. Nucleotides are composed of sugar, a phosphate group, and a nitrogenous base. ATP, DNA and RNA are all examples of nucleic acids. Nucleic acids are one of the four basic kinds of organic molecules.

Detailed explanation-5: -DNA (deoxyribonucleic acid) RNA (ribonucleic acid) 22-Mar-2016
