Answer 1

To complete the mRNA sequence from the given DNA sequence (TAC CGC CCC), we need to transcribe it.

1. The DNA sequence is:

   • TAC
   • CGC
   • CCC

2. Using the base-pairing rules (A pairs with U, T pairs with A, C pairs with G, and G pairs with C), we will convert the DNA sequences into mRNA codons:

   • TAC (DNA) → AUG (mRNA)
   • CGC (DNA) → GCG (mRNA)
   • CCC (DNA) → GGG (mRNA)

So the final mRNA sequence is:

• AUG GCG GGG

Next, we can identify the amino acids for each mRNA codon:

1. AUG corresponds to Methionine (Met) and also serves as the start codon.
2. GCG corresponds to Alanine (Ala).
3. GGG corresponds to Glycine (Gly).

Now, filling in the response areas:

mRNA: AUG GCG GGG
Amino Acid: Met Ala Gly

So, the complete responses would be:

mRNA: AUG | GCG | GGG
Amino Acid: Met | Ala | Gly
