Which of the following characteristics of chloroplasts make them seem more similar to bacterial cells than to eukaryotic cells?

ANSWERS:

Translation is sensitive to chloramphenicol

Alternate codons are found in the chloroplast genome

Introns are present in genes

DNA is not arranged in nucleosomes

Solutions

Expert Solution

Option A) Translation is sensitive to chloramphenicol, and Option D) DNA is not arranged in nucleosomes are the correct answers.

Option A) Chloramphenicol inhibit protein synthesis ( Translation) in bacteria as well as in chloroplast. It inhibit the activity of peptidyl transferase and prevent protein chain elongation.

This effect is seen in chloroplast and bacterial cell and not seen in Eukaryotic cell. Hence, it makes chloroplast more similar to bacterial cell than of Eukaryotic cell.

Option D) Bacterial cell has thier DNA in circular components called Plasmids. Chloroplast has thier DNA in plasmid like components.

DNA of bacteria and Chloroplast is not found coiled around histone proteins. But the DNA of Eukaryotic cell is found coiled around protective histone proteins called Nucleosomes ( Nucleosomes means DNA around histone).

As these nucleosomes are not found in bacteria and chloroplast and are found in Eukaryotic cells. Hence, it makes chloroplast more similar to bacterial cell than Eukaryotic cell.
