IB Biology HL D1.1.7 Hl Leading Vs Lagging Strand Questions

IB Biology HL D1.1.7 compares continuous leading-strand synthesis with discontinuous lagging-strand synthesis. The lagging strand is built as Okazaki fragments using repeated RNA primers.

Exam points

Identify that the lagging strand uses repeated RNA primers to form Okazaki fragments.

[Maximum number: 1]

What is a difference between the leading and lagging strands in DNA replication?

Fewer Okazaki fragments are produced on the leading strand.

Exons are only produced on the lagging strand.

More RNA primers are assembled on the lagging strand.

DNA nucleotides are linked $5^{\prime}$ to $3^{\prime}$ on the leading strand and $3^{\prime}$ to $5^{\prime}$ on the lagging strand.
