DNA It's the coding strand by default!

Is it true that DNA sequence is given in coding strand in USMLE by convention, unless specified otherwise?

I believe the OP is asking about discerning between the coding strand and the template strand, not the polarity of the sequence.

yes i am saying the same thing that always coding strand is given and when the question doesnt mention whether its a coding strand or template we should always assume it as a coding strand.

Hi, thanks to all,


So there are at least two conventions:

Unless specified, DNA sequence
1, is given from 5' to 3'
2, is represented by coding strand instead of template strand.

The 5' - 3' convention is stated in KN, but where is the coding strand stated? Pls provide the official source

Struggle, your statement is correct. DNA is conventional given from 5 to 3. You are also correct that coding strand is given unless specified, although two conventions are independent of each other.
