বহুনির্বাচনি (MCQ)
১. Okazaki fragments are formed during DNA replication on the:
ক) Leading strand
খ) Lagging strand
গ) Both strands equally
ঘ) RNA primer only
ঙ) Template of reverse transcriptase
উত্তর দেখুন
সঠিক উত্তর: খ) Lagging strand
ব্যাখ্যা: DNA polymerase works only 5' to 3', so the lagging strand is copied discontinuously in short pieces (Okazaki fragments) that are later joined by DNA ligase.
