Answer: Rhinoceros
Explanation:
Odd-toed ungulates include the horse, the tapir, and the rhinoceros.
I believe the miRNAs control gene expression by binding to mRNAs and degrading them or blocking their translation. The microRNAs are short non coding RNAs which function to regulate the process of gene expression. They bind to the 3-UTR of the target mRNAs and repress the production of protein by destabilizing the mRNA and translational silencing.
If a hypothesis is supported consistently by different observations or experiments, it may be advanced to the level of a(n) <u>theory</u>.
