Question

Which property of dna is used as a tool in genetic engineering?

Answer 1

Complementarity is a property of DNA that is used as a tool in genetic engineering. It states that when two strand of DNA are aligned antiparallel to each other, the nucleotide bases at each position will be complementary, i.e. according to Watson-Crick base pairing rule Adenine will pair with thymine by two hydrogen bonds while guanine will pair with cytosine by three hydrogen bonds.
