Underneath the right side of the liver, the gallbladder is a pear-shaped organ.
<h3>
What is the function of gall bladder?</h3>
Its primary function is to gather and concentrate bile, a digestive fluid made by the liver. The gallbladder is where bile is kept after the liver produces it. The gallbladder receives a signal from the stomach when you eat. Bile is released from the gallbladder when it contracts, and it travels through the gut via the major common duct. Bile combines with the food there and aids in digestion.
When the gallbladder is removed from a healthy person, there are rarely any obvious health or digestive issues, though there is a slight chance of diarrhea and fat malabsorption.

Explanation:
This site will tell you what you need to know.
Answer:
(C) Aminoacyl-tRNA synthetases have an additional active site that binds to non-cognate tRNAs. The tRNAs that bind to this second active are hydrolyzed and released from the enzyme.
Explanation:
In case of translation, proof reading is done by aminoacyl-tRNA synthetases only. Aminoacyl-tRNA synthetases have two mechanisms to avoid error during translation which are mentioned as under:
<u>(1) Chemical proof reading:</u> Incorrect amino acids rather than being hydrolyzed in catalytic pocket get hydrolyzed in editing pocket and thus they hardly get attached to tRNA.
For example: For distinguishing similar amino acids like isoleucine and valine, isoleucyl-tRNA synthetase uses a second active site which is meant for only valine not for isoleucine. In this particular site, valine which had entered the enzyme is cleaved away with the help of editing reaction after which the enzyme is well prepared to process isoleucine which is the correct amino acid for this enzyme.
<u>(2) Kinetic proof reading: </u>Even if an incorrect amino acid has entered a particular aminoacyl-tRNA synthetase, it does not cause appropriate conformational change in the enzyme because of which the incorrect amino acid loosens from the enzyme and does not get incorporated.
Note: In this example, only chemical proof reading is mentioned not kinetic proof reading.
Answer: Transcription is the synthesis of RNA from DNA while Translation is the synthesis of a protein from RNA.
