Answer: codons are read with no gaps between them.
- A codons are read with no gaps between them
- B one codon can code for many amino acids
- C a codon overlaps with the next codon
- D each codon needs a spacer base after it
Correct answer: A. codons are read with no gaps between them
Explanation: A comma-less code is read continuously without any punctuation or spacer bases between adjacent codons.
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'.
