Similar to Many condensation reaction Or polymerisation reaction the Byproduct of reaction is water.In the Below Figure during the Condensation Reaction between adenine and thymine, the OH group at 3’ position of Adenine reacts with OH group ofPhosphate group present in Thymine (at 5’position ) forms a phospho Linkage .hence the condensation Reaction is completed by liberating water (H2O).

DNAase are group of enzymes which cleaves the DNA in their phosphor diester bond through hydrolytic cleavage. DNAase are very specific with their substrate which is DNA but not other biomolecules like RNA , Protein etc.There are two types of DNAase (1)Exonuclease – acts on the ends of DNA only egLamda Exonuclease (2) Endonuclease acts inside the DNA Eg Restriction enzymes or molecular scissors like ECOR1 which are site specific in nature.

DNA (De oxy ribose Nucleic acid )is nothing but the genetic material present in our body(not only in human but also in several living things like Bacteria eg E.coli., Bateriophages eg lamda ,animals , Birds etc) .DNA is actually a polymer on four Nucleotides namely Adenine , Cytosine ,Thymine and Guanine .In the above base pairs(Nucleotides) Adenine is always paired by Thymine and similarly Cytosine with Guanine. The DNA is a polymer which is a double strand helix in structure in which the double strand is formed due to Hydrogen Linkage. In the single strand the nucleotides are connected or condensed or polymerised due to phosphor di ester bond formation between them....
