Hind $II$ cuts the $\text{DNA}$ molecule at a particular point by recognizing a specific sequence of how many base pairs?

In vector $\text{pBR-322}$,the $\text{Rop}$ codes for the $:-$

Discuss with your teacher and find out how to distinguish between (Any two):
$(a)$ Plasmid $DNA$ and Chromosomal $DNA$
$(b)$ $RNA$ and $DNA$
$(c)$ Exonuclease and Endonuclease

An antibiotic resistance gene in a vector usually helps in the selection of

Plasmid is used as a carrier (vector) because:

Statement-$I$: Thermostable $\text{DNA}$ polymerase is isolated from $\text{Thermus aquaticus}$.
Statement-$II$: $\text{Taq}$ $\text{DNA}$ polymerase is inactive at high temperature $(72^{\circ}\text{C})$.
