Answer 1

To determine if each amino acid sequence would code for hemoglobin based on the provided amino acid sequence (Pro-Glu-Glu-Lys: Proline, Glutamic acid, Glutamic acid, Lysine), we first need to convert each nucleotide sequence into its corresponding amino acids using the genetic code.

1. AUG CUG UAA UGG:

   • AUG: Methionine (Start codon)
   • CUG: Leucine
   • UAA: Stop codon (does not code for an amino acid)
   • UGG: Tryptophan
   • Answer: No

2. GGC CTT CTT TTT:

   • GGC: Glycine
   • CTT: Leucine
   • CTT: Leucine
   • TTT: Phenylalanine
   • Answer: No

3. CCC GAA GAA AAA:

   • CCC: Proline
   • GAA: Glutamic acid
   • GAA: Glutamic acid
   • AAA: Lysine
   • Answer: Yes

4. CCC GAA GAA AAG:

   • CCC: Proline
   • GAA: Glutamic acid
   • GAA: Glutamic acid
   • AAG: Lysine (This is another codon for Lysine)
   • Answer: Yes

Summary of Answers:

• AUG CUG UAA UGG: No
• GGC CTT CTT TTT: No
• CCC GAA GAA AAA: Yes
• CCC GAA GAA AAG: Yes
