Proteins, in eukaryotic cells (plants, animals, fungi) are made during protein synthesis, in which a gene encoding a specific protein's amino acid sequence is first transcribed in the nucleus, from DNA into messenger RNA (mRNA), then the mRNA is translated into the amino acid sequence at a ribosome.
The ribosome may be free-floating in the cytoplasm, or attached to the rough endoplasmic reticulum (rE.R.), depending on where the protein will end up.
If synthesized at the rE.R. then the protein will be packaged into an E.R. vesicle, which buds off and travels to the Golgi apparatus, where it attaches and the protein is further modified at the Golgi. This may include further 3-dimensional folding, adding of other moieties such as sugars (to make glyco-proteins), etc.
After post-translational modifications are complete, the modified protein can then be exported in a Golgi vesicle, budding off to travel to, for example, for export via exocytosis out of the cell. This happens for protein hormone secretions, enzyme secretion, and many other protein destinies.

Can someone please explain what gives air its weight?
maks197457 [2]
Simple. Air has mass. And if air has mass it also has weight. You can feel air when the wind blows. Or do an experiment. Weigh an empty container. Then pump it to a vacuum. Weigh it again. The difference is the weight of the air inside.

Translation ends when
Y_Kistochka [10]

<span>Translation

</span>Remember that transcription happens in the nucleus as it changes from DNA to mRNA.  In translation,
    the mRNA first has to leave the nucleus and go into the cytoplasm of the cell.  The process of translation actually occurs in the cell’s ribosomes.

<span>
</span>The process of translation uses the genetic code on the mRNA strand to direct the construction (making) of a protein molecule. <span>
</span>1.  A ribosome attaches to an mRNA molecule in the cytoplasm.<span>
</span>2.  As each codon passes through the ribosome, tRNA molecules bring the matching amino acids into the ribosome.  Each tRNA has a set of 3 unpaired nitrogenous bases called an anticodon which matches up with the codon coming through the ribosome.  So one end of a tRNA has an anticodon and the other end carries the amino acid which is how the code is translated.<span>
</span>3.  The ribosome and the rRNA molecules it contains attach the amino acids together as they are being translated.  The protein chain will keep growing until the ribosome reaches the stop codon on the mRNA.  At that point, translation is done and the ribosome lets go.


Hope this helps!!!

PLEASE HELP!!!!<br> How does the FDA regulate the animals?
Gnoma [55]

Whenever a new drug, device, or food, is developed for use in animals, It has to be approved by the FDA before it can be sold and marketed to the public.

Don't use the exact words, I copied it from an FDA website so change the wording first before you submit. Good luck Lol.
