Hello!
Here, the number of hydrogen bonds present in the sequence of a stretch of a double bond helical DNA is 19.
Here, A always combines with T by 2 H-Bonds and G combines with C by three h-bonds. Hence, total number of bonds present is equal to sum of the bonds that is equal to 19.
Hope this Helps!
