Interpretation Introduction

Interpretation:

DNA replication is semiconservative; the reason has to be discussed.

Concept Introduction:

Replication of DNA: The process by which copies of DNA are made when a cell divides. During cell division, the DNA in the nucleus undergoes replication. Initially, partial unwinding of double strand is achieved by the use of an enzyme called helicases; unwinding occurs in many specific locations known as origins of replication. At the site of replication forks, DNA polymerases move onto the leading separated strand, one by one specific base of triphosphate nucleotide form hydrogen bonds (A pair with T; G pair with C). In new double helix, one strand is template (leading strand) and other is newly synthesized strand (named as semiconservative strand).
