Class 12 NEET Biology Molecular Basis of Inheritance Questions Part 2

A transcription unit of DNA is defined primarily by the three regions in the DNA:
(i) A promoter
(ii) The structural gene
(iii) A terminator
The promoter is said to be located towards 5'-end (upstream) of the structural gene (the reference is made with respect to the polarity of coding strand)
The terminator is located towards 3'-end (downstream) of the coding strand.
