1) ATGGTAGTGCATCTTTGA (because the whole reason the coding DNA strand is called the 'template strand' is that the mRNA sequence is identical to it, other than the Thymine in the case of mRNA which is swapped for Uracil)
2) TACCATCACGTAGAAACT (the non-coding strand must be complementary to the coding strand)
3) TACCATCACGTAGAAACT (the tRNA sequence must be complementary to the mRNA strand)
4) Unsure but if I had to guess I'd say TGA...
