Here are the general rules for pairing nucleotide bases:

If you're looking for the complementary strand or the template strand of the DNA, remember this base-pairing rule:

Adenine (A) = Thymine (T)

Thymine (T) = Adenine (A)

Guanine (G) = Cytosine (C)

Cytosine (C) = Guanine (G)

And when you transcribed the DNA chain into mRNA, Adenine will be paired up with Uracil instead of Thymine. As for Guanine and Cytosine, lagi po silang pair and hindi mapapaghiwalay (sabaok emz).

Base-pairing rule for mRNA:

Adenine (A) = Uracil (U)

Thymine (T) = Adenine (A)

Guanine (G) = Cytosine (C)

Cytosine (C) = Guanine (G)

So let's try to answer two of your questions, the rest of the numbers will remain unanswered, para naman ma-challenge ka sis and Brainly is peer-to-peer learning app, dibaa let's collaborate!

1. DNA Coding : ATG TAC TAA GCC CAT TGA

DNA template : TAC ATG ATT CGG GTA ACT

mRNA strand : AUG UAC UAA GCC CAU UGA

2.DNA Coding : TAT GGC ATA TCA CCA AAT

DNA template  : ATA CCG TAT AGT GGT TTA

mRNA strand: UAU GGC AUA UCA CCA AAU

Again, if may questions or clarification don't hesitate to ask. If I can do it, I believe you can do it too! I hope it helps!
