Select the correct option with respect to transcription.

	Direction of RNA synthesis	Direction of reading of the template DNA strand
1	5' →3'	3' →5'
2	3' →5'	5' →3'
3	5' →3'	5' →3'
4	3' →5'	3' →5'

DNA-dependent RNA polymerase  catalyse the polymerisation in only one direction, that is, 5'→3' and therefore direction of RNA synthesis is 5' →3'.

The strand that has the polarity 3'→5' acts as a template, and is also referred to as template strand.
