Question

Define DNA replication. In which phase of cell cycle does

replication occur in Eukaryotes ? Describe briefly the mechanism of
DNA replication.

Answer 1

DNA replication is the process of formation of daughter DNAs. And in Eukaryotes DNA replication occur in S phase.

Step-by-step explanation:

there are four phases

• G1 phase
• S phase
• G2 phase and
• M phase.

DNA replication contain three steps

• Initiation = DNA helix is separated or unwinded by an enzyme helicase and two replication forks are formed.
• Elongation= Addition of a primer sequence. Lagging strand and leading strand formation occur.
• Termination= Primers are removed and sealed by DNA ligase.
