Explanation:

Step1: DNA base pairing rules (replication)

DNA pairs: A↔T, G↔C. For replication, DNA original matches copy.

Step2: DNA→RNA transcription rules

DNA A→RNA U, DNA T→RNA A, DNA G→RNA C, DNA C→RNA G.

Problem #5

Step1: Find DNA Original

DNA Copy: T G A A G T A G C G C A G T A
DNA Original pairs: A C T T C A T C G C G T C A T

Step2: Transcribe to RNA

RNA: U G A A G U A G C G C A G U A

Answer:

(Problem #5):
DNA Original: A, C, T, T, C, A, T, C, G, C, G, T, C, A, T
RNA: U, G, A, A, G, U, A, G, C, G, C, A, G, U, A

Problem #6

Step1: Find DNA Original from RNA

RNA: U A G C G U G U A C G C U A A
DNA Original (reverse transcribe): A T C G C A C A T G C G A T T

Step2: Find DNA Copy

DNA Copy pairs with original: T A G C G T G T A C G C T A A
