Explanation

A-5, B-3, C-2, D-4, E-1. The phenomenon of Operon was first discovered by Jacob and Monod in E coli. This is called lac Operon. It describes the ability of E coli to utilize lactose. Ori C is the point in bacterial DNA where replication of its DNA starts. All the genes of a DNA does not code for protein. The coding genes are called Cistron. Histones are bead like structures made up of proteins that helps in super coiling of DNA inside a cell. Jumping genes are called Transposons. Transposons are found in viruses.
