I can not figure out the answer for this problem

Question

Which of the following is true about nucleic acids?

1.  Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
2.  Glucose, cellulose, and starch are examples of nucleic acids found in most cells.
3.  Nucleic acids are usually insoluble in water and are used for long term energy storage.
4.  Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.

Answer 1

Nucleic Acids.

1. DNA (structure contains a five carbon sugar/deoxyribose, one phosphate group and nitrogenous bases)
2. RNA (structure contains a five carbon sugar/ribose, three phosphate groups and nitrogenous bases)

Carbohydrates

1. Glucose
2. Cellulose
3. Starch

Lipids

1. includes triacyclglycerols (energy storage) and are insoluble in water

Answer 2

1.  Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids. FALSE
2. both RNA and DNA are nucleic acids but DNA does not encode protein sequences, RNA does.
3.  Glucose, cellulose, and starch are examples of nucleic acids found in most cells. FALSE
4. Glucose, cellulose, and starch are carbohydrates not nucleic acids.
5.  Nucleic acids are usually insoluble in water and are used for long term energy storage. FALSE
6. Fats are insoluble, Nucleic Acids are soluble
7.  Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups. TRUE << Correct answer
