Expert Solution

Ans- Transcription is the process of synthesis RNA from DNA. DNA is double-stranded, but only one strand of DNA used as a template (minus strand) for transcription process. And this template strand of DNA is called non- coding strand. And, the other non-template (plus strand) strand of DNA is called coding strand because it's sequence will be same as that of new RNA transcript. Hence, During transcription process only one strand of DNA used as template strand for RNA synthesis that is called as non-coding strand. RNA polymerase enzyme read template strand (minus strand) of DNA for RNA transcript synthesis.

diagram showing synthesis of mRNA transcript from DNA template strand. And different names of DNA template and non-template strand mentioned in bracket.
