Question

Which of the following describes a structure that both prokaryotic and eukaryotic cells have in common?

This membrane-bound organelle encloses the cell’s DNA and is where DNA replication occurs.
This organelle is composed of a stack of membrane sacs where proteins are modified and stored.
This organelle extracts energy stored in glucose molecules to power cell functions.
This organelle is composed of protein and RNA and is used to make proteins for the cell.

Answer 1

Ribosome is composed of protein and RNA and is used to make proteins for the cell and is a common structure between prokaryotes and eukaryotes.

Explanation:

Ribosome in Prokaryotes has 2 subunits of 50S and 30S. They are composed of rRNA. It is in ribosome the protein synthesis of prokaryotes takes place. The ribosome in prokaryotes float free in the cytosol.

Ribosome in eukaryotes is larger and has 2 subunits of 60S and 40S. Ribosome is made up of ribonucleoproteins. They synthesize proteins based on the information from mRNA. The ribosome in eukaryotes is membrane-bound.
