Monomer is a single organic molecule that can be bound in a chain.
polymer is a chain or a series monomer
Answer:
Explanation:
Based on their feeding habits, we will regard the raccoons as omnivores. Omnivores are organisms that possess the ability to feed and survive on both plant and animal matter.
These raccoons eat invertebrates etc which are animal matter and then different fruits and vegetables etc; plant matter.
Thus, they can be regardless as being an omnivore.
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:
B
Explanation:
You can't change your DNA as far as I know and if you inherit exact copies of DNA from your parents that means you're a clone which human clones don't exist. You inherit genes from both your mother and father i.e you have blue eyes like your dad and brown hair like your mom.
