The cell is showing transport of protein and RNA between the nucleus and cytoplasm. As soon as the chemical is injected the transport of proteins and RNA has stopped. The chemical is targeting ____________.

Option: 1


Option: 2


Option: 3


Option: 4

Nuclear pore

Answers (1)


Molecules can go through the nuclear envelope thanks to nuclear pore complexes. In addition to proteins (including DNA polymerase and lamins), carbohydrates, signaling molecules, and lipids migrating into the nucleus, this transport also involves the movement of RNA and ribosomal proteins from the nucleus to the cytoplasm. Hence we can say that the chemical is targetting/blocking the nuclear pore which is responsible for transport. Hence, option 4 is the correct answer.

Explanation for the incorrect options :

Option 1 is incorrect because the nucleoplasm's main job is to act as a suspension medium for the organelles inside the nucleus. Additionally, it aids in preserving the nucleus's shape and structure.

Option 2 is incorrect because the nucleolus is a spherical component of the cell's nucleus whose main job is to assemble and generate ribosomes. Additionally, ribosomal RNA genes are translated in the nucleolus.

Option 3 is incorrect because to produce chromosomes, chromatin fibers are coiling and condensing. Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.
