He process of transcription and translation is carried out in a test tube. To a test tube is added: 1. from a hippo: messenger RNA (mRNA), transfer RNA’s (tRNA), ribosomes 2. from a fish: DNA 3. from a zebra: RNA polymerase + other necessary enzymes; ribonucleotides & amino acids. Assume some new protein is synthesized by this cell-free system in the test tube. The proteins of which animal(s) will be expressed?

The proteins of both hippo and fish will get expressed.

Explanation:

In the given case, it is mentioned that from hippo, the mRNAs, tRNAs, and ribosomes are added in the system, thus, the mRNA of hippo is getting all the necessary things like tRNAs and ribosomes to go through the process of translation and thus exhibits the tendency to give rise to the proteins of hippo.  

Similarly, the DNA taken from the fish can use the RNA polymerase, ribonucleotides, and other essential components from the system, which is taken from the zebra. These components can help the DNA to go through the process of transcription, and the mRNA produced in the process can further go through the process of translation and generate the proteins of the fish.
