Question

In many eukaryotic cells, DNA stored in the nucleus is transcribed into messenger RNA. The mRNA is then transported into the cytoplasm where ribosomes assist in their translation into proteins. Finally, these proteins are packaged and sorted in the Golgi apparatus for use in other parts of the cell or in preparation for secretion into other cells. Which of the following statements is supported by this description?

Answer 1

Answer:

The statement supported by the description of the process of protein synthesis determined by DNA and its packaging and sorted by the Golgi apparatus is that various organelles within a cell interact with each other to carry out life processes (option D).

Explanation:

From the transcription of RNA from DNA to protein synthesis and its packaging and distribution, the participation of organelles is observed:

• Cell nucleus: contains the DNA and is where the transcription into mRNA occurs.
• Ribosomes: where the mRNA is coupled to produce translation and protein synthesis.
• Rough endoplasmic reticulum: contains ribosomes and participates in the process of membrane protein synthesis, also contributing to their conjugation, glycosylation or sulfonation.
• Golgi apparatus: it is in charge of receiving synthesized proteins, packaging and distributing them to be sent to the extracellular space or other cells.

In this way, the coordination of the functions of various organelles is useful and necessary to fulfill vital functions. The statement that varoius organelles within the cell interact with each other to carry out life processes is, therefore, correct.

The options for this question are:

    A.  Organelles within a cell act independently of each other at all times

    B.  Some organelles are more important than other organelles within a cell.

   C.  Only up to three organelles may interact with each other at any given moment in time.

   D.  Various organelles within a cell interact with each other to carry out life processes.
