An error occurs when the DNA of a cell is copied. However, the cell does not divide after the error is detected. Which statement

best describes the cell cycle for this cell?

The statement would be "An Error during S phase is corrected during the G2 Phase"

S phase is used to describe DNA Replication ,

In G2 Phase, the cells are making sure that all the problems are fixed before they enter mitosis. It's common for the cells to do apoptosis (cell suicide) if they cant fix the error

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.

Agata [3.3K]

The molecule C-P phosphorylates and thus activates D, whereas Kinase D amplifies cellular signaling by phosphorylating many substrates. In this case, it is expected to observe kinase D overexpression in Brec-MUT cells.

<h3>Cancer, phosphorylation and signaling pathways</h3>

Cancer can be defined as a multifactorial disease, which is often associated with uncontrolled cell growth.

Cancer signaling may be associated with defective pathways such as, for example, a mutated kinase protein that affects normal downstream molecular cascades.

A kinase is a specific protein that acts to phosphorylate specific cellular substrates, thereby activating/deactivating a particular signaling pathway.
