What are the subunits of nucleic acids?

Answer 1

Nucleic acids consist of 3 subunits.

The four nucleotides that make up DNA are: adenine (A) - a purine; cytosine (C) - a pyrimidine; guanine (G) - a purine; thymine (T) - a pyrimidine. The nucleotides are made up of a sugar (deoxyribose) in the middle of a phosphate group and a nitrogenous base. There are two classes of bases: two purines (double-ringed structures) and two pyrimidines (single-ringed structures).

The primary chemical difference between RNA and DNA is the substitution of uracil for thymine as a base material. RNA also contains ribose as its sugar instead of deoxyribose. DNA and RNA both have four major bases, but RNA has the first three plus uracil.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
