mRNA or simply RNA. It gets translated by ribosomes into proteins, so there would be ribosomes on RNA. The four nitrogenous bases that compose RNA are Adenine, Guanine, Cytosine, and Uracil. If there were Thymine instead of Uracil, then it would be DNA. RNA also has sugars (ribonucleic acids) and phosphate groups in its backbone. Therefore, this component of the new organism is RNA. Hope this helps! :)
