Watson and Crick proposed which mode of DNA replication?
ADispersive — fragments of old and new mixed
BConservative — original double helix preserved; new helix is fully new
CSemi-conservative — each new molecule has one parental and one newly synthesised strand
DRandom
Answer & Solution
Correct answer: C. Semi-conservative — each new molecule has one parental and one newly synthesised strand
Watson-Crick predicted **semi-conservative replication**: each strand serves as template for a complementary new strand. Each daughter helix has **one old + one new strand**.
