Choose the correct answer from the options given below:
The elucidation of $Lac$ operon was a result of a close association between geneticist, Francois Jacob and a biochemist, Jacques Monod.
Meselson and Stahl gave semi-conservative mode of $DNA$ replication.
Har Gobind Khorana developed chemical method to define combination of bases in genetic code.

$ii. \;RNA \;polymerase \;II \;transcribes \;snRNAs.$
$iii. \;RNA \;polymerase \;III \;transcribes \;hnRNA.$
$iv. \;RNA \;polymerase \;II \;transcribes \;hnRNAs.$
