Answer:

The complementary strands of DNA ____Unwind__________ to form a _Y___-shaped replication fork New __Neucleotide base______ pairs are formed according to base pairing rules Each double-stranded DNA is made of one _old____ strand and one ___new_______ strand of DNA

Explanation:

Central dogma is the process by which proteins are synthesized from genetic information. It comprises of replication, transcription and translation. In replication the new copy of DNA is synthesized.

  • The double stranded DNA is unwound by helicase enzyme.
  • A primer is added by RNA polymerase to start replication by DNA polymerase.
  • DNA polymerase can add the nucleotides in only in 5' to 3' direction so it synthesizes one strand of DNA continuously known as "leading strand" and  one strand in fragments known as "lagging strand"
  • Ligase enzyme join the fragments of lagging strand.
  • The new DNA molecule contains the one old strand and one new strand
