CAN SOMEBOdy explain this to me PLEASE!!

Answer:
When transcribing DNA into RNA, you just flip the letters to the opposites. But because Thymine isn't in RNA, you convert all the A's in the sequence into U, and all the T's into A.
I didn't do your problem, but here:
Ex: ATTAGCTATCGCCCCTCGATAGGG
Step 1: break the sequence into codons, or 3 at a time.
ATT AGC TAT CGC CCC TCG ATA GGG
Step 2: Convert the codons to get your transcription of RNA.
UAA UCG AUA GCG GGG AGC UAU CCC
Step 3: look at you chart, and in the order the new codons go in to get your genetic message.
Step 4: You're done!
Step 5: Congratulations, you learned something.
