The chemical mechanisms used to avoid errors in protein synthesis are different from those used during DNA replication. DNA poly
Savatey [412]

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.

Passwords, tokens, and fingerprint scans are all examples of ________. identification authentication authorization credentials
julia-pushkina [17]
The answer to the fill in the blank is option B) Authentication


Passwords, tokens, and fingerprint scans are all examples of Authentication.

We use passwords, tokens and even fingerprints since they can be unique identifications and are usually seen as more secure.

In the above options, fingerprints are seen as the most secure form of authentication since everyone has unique fingerprints.

One of the earliest forms of authentication were time cards used as early as the 1950s and even unique keys and stamps used by early civilizations.
