Solution(By Examveda Team)

The coding strand of DNA has the polarity 5' - 3'.
DNA is double-stranded, but only one strand serves as a template for transcription at any given time. The coding strand is the strand used when displaying a DNA sequence. It is presented in the 5' to 3' direction.
This template strand is called the noncoding strand. The non-template strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule.
