Answer:

The RNA strand that is transcribed from the DNA strand sequence ATG-CAG-AGA is UAC-GUC-UCU, according to the complementarity of nitrogenous bases.

Explanation:

In order for DNA to RNA transcription to occur, one must be aware that:

  1. The transcription meets the criteria of base complementarity, where a purine binds to a pyrimidine.
  2. In RNA there is no thymine, so it is replaced by uracil.  

Given a given sequence of bases the RNA resulting from transcription will be governed by these rules:

DNA: ATG-CAG-AGA

RNA: UAC-GUC-UCU

Where:

  • Adenine is transcribed in Uracil.
  • Thymine (DNA) is transcribed into Adenine.
  • Cytosine is transcribed into Guanine.
  • Guanine is transcribed into Cytosine.
