Question

The method of DNA replication is _____________

(a) conservative

(b) semi-conservative

(c) non-conservative

(d) disruptive

I had been asked this question by my college director while I was bunking the class.

I need to ask this question from Genes, Chromosomes and Genomes topic in chapter Bioenergetics, Enzymes, Metabolism, Genes, Chromosomes and Genomes of Cell Biology

Answer 1

Right option is (b) semi-conservative

For explanation I would say: In DNA replication , the two daughter strands unwind and are used as template for the formation of a new DNA strand. As a result, one strand in conserved and a new strand is produced by taking the conserved strand as a template. Thus, DNA replication is a semi-conservative process.
