Answer:
The bases found in a DNA strand are adenine (A), thymine (T), guanine (G) and cytosine (C).
Step-by-step explanation:
Nitrogen bases are compounds that are part of the composition of DNA and RNA, which are the nucleic acids found in living organ cells.
They are five and can be classified into two types:
- Purine or purine bases - adenine and guanine
- Pyrimidine or pyrimidine bases - cytosine, thymine and uracil.
DNA is composed of the following bases:
- Adenina (A) e guanina (G), que são bases púricas.
- Citosina (C) e timina (T), que são bases pirimídicas.
