nitrogenous base
phosphate
ribose

Answer 1

Answer:

phosphate is right answer brother.

please mark me brainliest.

Answer 2

Ribose is not part of a molecule of DNA.

Explanation:

• The DNA and the RNA are considered as genetic material.
• The component of both DNA and RNA are:

1. Pentose sugar
2. Nitrogenous base
3. Phosphate group

• In DNA:

1. Pentose sugar is Deoxyribose sugar.
2. Nitrogenous bases are Adenine, Guanine, Cytosine and Thymine.
3. Phosphate group

• In RNA:

1. Pentose sugar is ribose sugar.
2. Nitrogenous bases are Adenine, Guanine, Cytosine and Uracil.
3. Phosphate group

• Thus, it is inferred that, ribose is not a part of a molecule of DNA.
