Answer:
DNA always has these bases: A,T,C,G whilst RNA always has A,U,C,G (RNA never has T).
C and G are complementary, so if your DNA has C, the RNA will have G.
If your DNA has T, your RNA has A
If your DNA has A, your RNA has U
^ These rules always hold true.
To find the proteins formed, take your codon (3 bases on RNA) eg AUG and look at the diagram. First look at the green A section, then the red U section and then the G section. Your protein will be abbreviated to 3 letters eg ala or gly.
Explanation:
Hope this helps you.
The main thing you need to know is which bases are complementary, and that RNA (mRNA and tRNA never have T, they always have either U or A, and C or G.
