Question

select the true statements. all four dna nucleotides have identical 5 - carbon sugars. all four dna nucleotides have identical phosphate groups. all four dna nucleotides have identical nitrogenous bases.

Explanation:

DNA nucleotides consist of a 5 - carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base. The 5 - carbon sugar (deoxyribose) is the same in all four DNA nucleotides. The phosphate group is also identical in all four. However, the nitrogenous bases are different (adenine, thymine, guanine, cytosine).

Answer:

All four DNA nucleotides have identical 5 - carbon sugars.
All four DNA nucleotides have identical phosphate groups.
