### <p class="head">Scenario and Task</p>
DNA transcription is the process by which a strand of DNA is used as a template to construct a new molecule known as RNA by copying its nucleotides one at a time. During this process, one of the four DNA bases, Thymine (T), is replaced with the RNA base, Uracil (U).

Your task is to complete function `dna_transcription` which takes a `String` strand of DNA, transcribes it and returns the resulting RNA strand as a `String`. Every **Thymine (T's in the string)** base should be **replaced** with the RNA base, **Uracil (U's in the string)** as previously mentioned.

---

### `dna_transcription`
The `dna_transcription` function should accept a `String` argument and return a `String` of DNA correctly transcribed into RNA.

### <p class="head">Sample Results</p>

    dna_transcription("ATATCCGGAATT") // --> AUAUCCGGAAUU
    dna_transcription("ACTGACTG") // --> ACUGACUG
    dna_transcription("AACCGGTT") // --> AACCGGUU
    
    /* Khye's example */ dna_partner("AACCGGTT") // --> TTGGCCAA

---
Your function should work for any `String` argument. DO NOT HARDCODE!
