The volume of urine differ from the baseline measurement

Q1. Drag the ADH bottle cap to the gray cap on the top right side of the nephron tank, and release it to dispense ADH. Click Start, and allow the run to complete. Click Record Data. In this run, how does the volume of urine differ from the baseline measurement?

Q2. The large subunit of the ribosome is an RNPzyme, wherein the RNA forms the active site, but proteins are critical co-factors (image courtesy of T. Cech). Proteins (also called polypeptides) are formed from chains of linked amino acids. As with nearly all biological processes that involve nucleic acids, base pairing interactions play a key role in the translation of genetic information from mRNA into protein. How do we know that base pairing is key?
