Which of the following could be a nucleotide of dna?

a) deoxyribose + phosphate group + thymine
b) deoxyribose + phosphate group + uracil
c) ribose + phosphate group + thymine
d) ribose + phosphate group + uracil

A

Explanation:

Deoxyribosenucleic acid (DNA) is one of the two types of nucleic acids, the other being RNA. DNA is a polymer called polynucleotide made up of subunits called NUCLEOTIDE. Each nucleotide is made up of components that make up its structure. These components are:

1. A five-carbon sugar, which can be Deoxyribose or ribose depending on whether it is present in DNA or RNA respectively. The difference in the two sugars is the deficiency of one oxygen atom in deoxyribose.

2. Phosphate group with the structure PO3 (4-)

3. Nitrogenous bases, which are four in number viz: Adenine, Guanine, Cytosine and Thymine/Uracil. Thymine is only present in DNA while Uracil is only present in RNA.

Hence, the answer to the question is Deoxyribose, phosphate and Thymine (nitrogenous base).

the answer for this question would be d. glaciers

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!
