Look at Q1bii)
"Give the DNA base sequence that codes for threonine"
--------

So the DNA base sequence that CODES is on the sense strand
mRNA is complementary to the anti-sense strand and identical to the sense strand (except T is replaced by U)

So the codons on mRNA should be the same as the coding DNA strand
hence the answer SHOULD BE ACC
BUT the answer given is TGG
why?
thanks

Cis or trans? That's what matters.

in such case, you should study little bit more. Especially in light of your next sentence:
"mRNA is complementary to the anti-sense strand and identical to the sense strand (except T is replaced by U)"

(is it possible to be both sentences correct?)
