प्रश्न
Differentiate between the following:
Template strand and Coding strand
उत्तर
| Template strand | Coding strand |
| It is also called antisense or (-) strand or master strand. | It is also called sense or (+) or non-template strand. |
| Template strand of DNA acts as a template for the synthesis of mRNA during transcription. | Coding strand is a sequence of DNA that has the same base sequence as that of mRNA (except thymine that is replaced by uracil in DNA). |
| It has 3'→5' polarity. | It has 5'→3' polarity. |
