1.	In which organism was the “Semiconservative theory of DNA replication” first observed?(a) Treponema pallidum(b) Vibrio cholerae(c) Staphylococcus pneumoniae(d) Escherichia coliI got this question in my homework.Enquiry is from The Experimental Proof of Replication of DNA topic in division Molecular Basis of Inheritance of Biology – Class 12
Answer» The correct option is (d) Escherichia COLI For explanation I would say: It was PROVED by WATSON and Crick that the DNA replicates semi-conservatively. This was first observed in Escherichia coli. Later, the same concept was observed in PLANTS and human CELLS too.
