Multiple Choice
Which organelle or cellular structure in bacteria is responsible for the production of green fluorescent protein (GFP)?
A
Nucleus
B
Endoplasmic reticulum
C
Mitochondria
D
Ribosomes
Verified step by step guidance1
Understand that green fluorescent protein (GFP) is a protein, and proteins in cells are synthesized by ribosomes.
Recall that bacteria are prokaryotic cells, which means they lack membrane-bound organelles such as the nucleus, endoplasmic reticulum, and mitochondria.
Recognize that in bacteria, protein synthesis occurs in the cytoplasm where ribosomes are freely floating or attached to the plasma membrane.
Identify that ribosomes are the cellular structures responsible for translating messenger RNA (mRNA) into proteins, including GFP if the gene is present and expressed.
Conclude that since bacteria do not have nucleus, endoplasmic reticulum, or mitochondria, the ribosomes are the organelles responsible for producing GFP.
