Question

Which elements are common to all four of the base nucleotides found in DNA? Select all that apply.

nitrogen
sodium
carbon
iron

Answer 1

Step-by-step explanation:

The nitrogenous bases of nucleotides are organic (carbon-based) molecules made up of nitrogen-containing ring structures. Why is it called a base? Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T)

Answer 2

nitrogen, carbon

Step-by-step explanation:

DNA nucleotide consists of a phosphate group, deoxyribose sugar and one of the 4 possible bases- adenine, guanine, cytosine and thymine.

The elements that are found in four of the bases are carbon, nitrogen and hydrogen.

Base pairing occurs between a purine and a pyrimidine. Purines are fused double ring structures and can be adenine or guanine, while pyrimidines are single ring structures and can be cytosine and thymine in the case of DNA.
