Respuesta :

Complementary DNA strand have the letters switched from each other. That would be:

A -> T OR T -> A
And
C -> G OR G -> C

As well as the direction of the strand:
5’ -> 3’ to 3’ -> 5’


For the first set:

DNA: 5’ - ATTATCGCGTAGCTAGCAGT - 3’
Comp: 3’ - TAATAGCGCATCGATCGTCA - 5’

As you can see the strands are the opposite from one another.

Try out the second set of strands and if you’re still having struggles let me know in the comments (:
