Answer: Unambiguous nature.
- A Degeneracy
- B Universality
- C Unambiguous nature
- D Wobble
Correct answer: C. Unambiguous nature
Explanation: The code is unambiguous: a specific codon always codes for the same amino acid in a given organism, without alternative meanings.
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.
