Define DNA replication. In which phase of cell cycle does
replication occur in Eukaryotes ? Describe briefly the mechanism of
DNA replication.

Respuesta :

Answer:

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

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.
