MCQ
In nucleic acids, the sequence is:
- APhosphate base sugar.
- BSugar phosphate base.
- CPhosphate - sugar base.
- DBase phosphate sugar.
✓
Answer
- Phosphate - sugar base.
Explanation:
In nucleic acids, the sequence is phosphate-sugar base. Nucleic acids are polymeric macromolecules, or large biological molecules, essential for all known forms of life.
Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides.
Each nucleotide has three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
If the sugar is deoxyribose, the polymer is DNA. If the sugar is ribose, the polymer is RNA.
