Question

Which of the following is true of DNA and RNA nucleotides? (4 points)

Both contain a sugar and a cytosine nitrogenous base.

Both contain a sugar and thymine nitrogenous base.

Both contain deoxyribose sugar and uracil nitrogenous base.

Both contain ribose sugar and cytosine nitrogenous base.

Answer 1

Both contain a sugar and a cytosine nitrogenous base.

Step-by-step explanation:

DNA and RNA are both nucleic acids. However, the nucleotides bases) that make up each molecule have slightly different structures.

DNA stands for deoxyribonucleic acid because the sugar in the nucleotides is deoxyribose sugar.

RNA stands for ribonucleic acid because the sugar in the nucleotides is ribose.

DNA contains the bases cytosine, guanine, adenine, and thymine.

RNA contains one base different, it has cytosine, guanine, adenine, and uracil.

Therefore, they contain different sugars, but they both contain a cytosine nitrogenous base.
