What is DNA replication?

1 Answer

The process where two new DNA are formed from an old one.


  • Old DNA's double strand unzips.
  • Free DNA nucleotides with extra phosphates pair up with the exposed bases.
  • Neighbouring DNA nucleotides' phosphate and sugars are joined with the help of DNA polymerase.
  • SO, two new DNA are formed each containing a strand from the old DNA.

This video provides a brief summary of this process using the DNA Workshop activity from PBS.
