A researcher incubates a cell with radiolabeled amino acids. These amino acids are incorporated into the proteins as they are sy

nthesized by the cell. Select which piece of data would indicate the incorporation of radiolabeled amino acids during protein synthesis? A) Radioactivity levels would increase first at the nucleus, followed by the Golgi, and then the cell membrane. B) Radioactivity levels would increase first at the nucleus, followed by the ribosomes, and then the secretory vesicles. C) Radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles. D) Radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the nucleus, and then the secretory vesicles.

Answer:

The incorporation of radiolabeled amino acids during protein synthesis occurs when the data shows the organelles involved with protein synthesis, packaging and transport, that is, radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles (option C).

Explanation:

Protein synthesis in the cell occurs when RNA -which contains the sequence of triplets or codons that make up the genetic code- is coupled to ribosomes.

Each codon or triplet, consisting of three nucleotides, will give instructions for specific amino acids to be incorporated into the polypeptide chain that is being synthesized in the rough endoplasmic reticulum.

The Golgi apparatus is responsible for packaging or packaging the newly synthesized proteins in secretory vesicles for transport.

<em>In consecuense, </em><u><em>radioactivity levels would increase in the organelles involved in protein synthesis, packaging and transport, the rough endoplasmic reticulum, Golgi apparatus and secretory vesicles</em></u><em>, respectively.</em>

REY [17]

Answer:

Motor protein kinesin can "walk" along a microtubule while carrying vesicles and by changing its shape the kinesin.

Explanation:

Motor protein kinesin is an important microtubule based motor protein that  is conserved among all eukaryotic organisms. Its movement along the microtubule is ATP powered. Most of the kinesins  walk towards the plus end of the microtubule.

Due to its ability it is responsible for unidirectional transportation of cargos including membranous organelles and mRNA.

Punnet squares are your friend with these kinds of questions :)

   <u>   A  |  a  |</u>
A <u>| AA | Aa |</u>
a <u>| Aa | aa |</u>

Now we can easily see that 1/4 of the offspring will be AA, 1/2 will be Aa, and 1/4 will be aa. Therefore, it is the third answer that's correct (1/4 AA, 1/2 Aa, 1/4 aa). Hope this helps! :)

dimaraw [331]

Answer:

Viruses are composed of one or more cells.

Explanation:

The viruses are microorganisms composed of genetic material protected by a protein envelope, and that´s how they work and live.  This protein membrane, (only present in some viruses), is carbon based.

By they way of fuction, they evolved along whit the cell in wich they are introduced, since they reproduce with it.

What is the primary role of the respiratory system in living organisms?
aliya0001 [1]
The primary role of the respiratory system in living organisms is B. TO OBTAIN OXYGEN.

Through the process of breathing, we inhale oxygen and exhale carbon dioxide. Oxygen is then transported by our blood to be distributed to the various parts of our body in order for these parts to function properly.

The absence of oxygen in the body will result to the gradual decline and death of our cells. When our respiratory system is compromised, it affects how our brain and heart function and may cause lasting damage if not quickly resolved.
