| Role/Strand |
Template strand |
Coding strand |
| Function |
Codes for the protein molecule |
Does not code for anything |
| Polarity |
3' ----> 5' |
5' ----> 3' |
Detailed answer:
The template strand of double stranded DNA has 3'---> 5'polarity and it transcribes RNA over it in 5' ---> 3' direction whereas its coding strand has 5'----> 3' polarity. It does not transcribe and code for anything.
It is because RNA polymerases the nucleotides only in 5'-3' direction. The coding strand is also called as the sense strand. It gets displaced during transcription.
