Replication (school) — Enzyme Names
What is it?
Helicase, polymerase, ligase (joins fragments). No kit list, no temperatures as a protocol. PCR is a named lab idea in some books — word only. Helicase unwinds. Primase makes RNA primer. DNA polymerase adds nucleotides. Ligase joins Okazaki fragments. All names for exams — no PCR temperature protocol. This page separates the idea from the wider topic “REPLICATION (SCHOOL)” so it can be revised and assessed on its own.
In simple words
- Helicase, polymerase, ligase (joins fragments).
- Leading vs lagging
- Exam link: polymerase adds.
Important terms
ENZYME NAMES: Helicase, polymerase, ligase (joins fragments).
REPLICATION (SCHOOL): DNA copies before mitosis/meiosis (S phase).
What you should learn
- Define enzyme names using accurate biology terms.
- Explain why enzyme names matters within replication (school).
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Examples
- Leading vs lagging
- Ligase seals
- No PCR recipe
KEY IDEA
Helicase, polymerase, ligase (joins fragments). No kit list, no temperatures as a protocol. PCR is a named lab idea in some books — word only. Helicase unwinds. Primase makes RNA primer. DNA polymerase adds nucleotides. Ligase joins Okazaki fragments. All names for exams — no PCR temperature protocol.
EXAM APPLICATION
Exam semiconservative: Helix opens. Each strand templates a new strand. Each daughter DNA has one parental strand.
Recommended for Class 11

WHY — Why this topic matters
REPLICATION (SCHOOL) — ENZYME NAMES is an independent FBISE learning unit because students must connect its structures and processes with their biological functions and examples.
HOW — How it works
Helicase, polymerase, ligase (joins fragments). No kit list, no temperatures as a protocol. PCR is a named lab idea in some books — word only. Helicase unwinds. Primase makes RNA primer. DNA polymerase adds nucleotides. Ligase joins Okazaki fragments. All names for exams — no PCR temperature protocol. Examples: Leading vs lagging; Ligase seals; No PCR recipe. Exam use: Exam semiconservative: Helix opens. Each strand templates a new strand. Each daughter DNA has one parental strand.

Common exam traps
- Do not treat enzyme names as the same as every other part of replication (school); define this unit and use its own evidence, steps, or conditions.
- Do not memorise a label alone; connect the definition to a process, structure, condition, equation, or example.
