what is the difference between coding and non coding strands?
Coding strand is that strand which has the same sequence as that of the newly transcribed mRNA. The direction of the coding strand is 5' to 3'. It is also called the sense strand or non template strand.
Non coding strand is that strand which has the sequence complementary to that of the newly transcribed mRNA. The direction of this strand is 3' to 5'. This is also called the template strand or antisense strand.
Hope this answers your question.
