Question 4
What does DNA stand for?
The right answer is the one marked above.
Deoxyribo Nucleic Acid. Its building unit is the deoxyribonucleotide.
RNA is Ribo Nucleic Acid, built from ribonucleotides. One letter of difference in the name, one difference in the sugar — and that is what separates the two kinds of nucleic acid found in living things.
