Answer:

Occurrence. In primary succession pioneer species like lichen, algae and fungi as well as other abiotic factors like wind and water start to "normalize" the habitat. Primary succession begins on rock formations, such as volcanoes or mountains, or in a place with no organisms or soil.

Polyribosomes are groups of ribosomes linearly arranged, associated with mRNA, and producing several copies of proteins. The coupling of processes shown in the image can not be found in eukaryotic cells.

<h3>What is a polyribosome?</h3>

A polyribosome is a group of single ribosomes associated with an mRNA molecule and producing simultaneous translation events of the same protein.

Polyribosomes can be found in both prokaryotic and eukaryotic cells. However, translation occurs at different moments and places in these cells.

⇒ In a prokaryotic cell

Polyribosomes can act before transcriptional termination occurs.

While transcription is still happening, ribosomes can produce many polypeptide copies.  

This is because

  • both transcription and translation occur in the cytoplasm simultaneously.

  • transcription and translation directions are 5' to 3'.

  • mRNA does not need to be modified after transcription.

⇒ In eukaryotic cells

Polyribosomes are found in the cytoplasm but only when

  • the transcription process is over,
  • the mRNA molecule is already modified and left the nucleus.

Since transcription occurs in the nucleus and translation in the cytoplasm, they can not be simultaneous.

According to this information, the coupling of processes shown in the image can not be found in eukaryotic cells.
