General ScienceChemistry
- A1 and 4
- B1 and 3
- C4 only
- D2 and 3
Explanation
DNA stands for Deoxyribonucleic Acid (statement 1 correct) and it can replicate, i.e., make a copy of itself (statement 4 correct). It is located in the nucleus (and mitochondria), not in ribosomes (statement 2 wrong), and it is composed of deoxyribonucleotides, not ribonucleic acid (statement 3 wrong). Hence 1 and 4, option (a).
