Question

Why is dna replication said to be semiconservative?

Answer 1

DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.

Answer 2

It is called 'semi-conservative' as both of the produced DNA molecules willcontain 1 new strand and 1 old, 'template' strand. (i.e. 1 old DNA strand is 'conserved' in each)
