Question

which of the following bacterial structures is the site of protein synthesis?
plasma membrane
ribosome
dna (chromosome)
cell wall

Explanation:

To determine the site of protein synthesis in bacterial structures:

• Plasma membrane: Mainly involved in transport and cell - environment interactions, not protein synthesis.
• Ribosome: Ribosomes are known as the site of protein synthesis in cells, including bacterial cells. They are responsible for translating mRNA into proteins.
• DNA (chromosome): DNA contains the genetic information (genes) that code for proteins, but it is not the site where the actual synthesis of proteins occurs. It is the source of the genetic code that is used by ribosomes for protein synthesis.
• Cell wall: The cell wall provides structural support and protection to the bacterial cell and has no role in protein synthesis.

Answer:

B. Ribosome
