Question

1. for each sequence of dna is shown, write the complementary rna sequence underneath the letters, then use the codon chart to determine the amino acid sequence;

dna→ t a c c a t g g a a g t a c t
rna→
amino acids →

Explanation:

Step1: Transcribe DNA to RNA (base pairing: A-U, T-A, C-G, G-C)

DNA: T A C C A T G G A A G T A C T
RNA: A U G G U A C C U U C A U G A

Step2: Translate RNA to amino acids (using codon chart: AUG - Met, GUA - Val, CCU - Pro, UCA - Ser, UGA - Stop)

Codon 1: AUG → Methionine (Met)
Codon 2: GUA → Valine (Val)
Codon 3: CCU → Proline (Pro)
Codon 4: UCA → Serine (Ser)
Codon 5: UGA → Stop (termination)

Answer:

RNA: AUG GUA CCU UCA UGA
Amino Acids: Met - Val - Pro - Ser - Stop
