Answer 1

To decode the provided DNA strands into mRNA, anticodons, and proteins, we can follow these steps:

1. **Transcription**: Convert the DNA sequence to mRNA by replacing Thymine (T) with Uracil (U).
2. **Translation**: Divide the mRNA into codons (groups of three bases) and use the genetic code to find the corresponding amino acids (proteins).
3. **Anticodons**: The corresponding tRNA anticodons can be derived from the mRNA codons.

Let's decode the provided strands:
