Answer: deoxyribonucleic acid.
- A deoxyribonucleic acid
- B dinucleic acid
- C diribose acid
- D double nucleic acid
Correct answer: A. deoxyribonucleic acid
Explanation: DNA is short for deoxyribonucleic acid.
Helicase unwinds the double helix at the replication fork; one new strand (leading) is synthesised continuously toward the fork, while the other (lagging) must be made in short, separate Okazaki fragments because DNA polymerase only adds nucleotides 5'→3'.
Concept context
DNA structure, replication, transcription, translation, the genetic code, and gene regulation (lac operon). The single most important chapter for NEET molecular biology.
