Question

Which structure or organelle is found in both prokaryotic and eukaryotic cells? A) ribosomes B) chloroplasts C) mitochondria D) endoplasmic reticulum

Answer 1

The ribosome is found in both the prokaryotic and eukaryotic cells.

Answer 2

The correct answer would be A) ribosomes.

A ribosome is a vesicular structure present in both prokaryotic and eukaryotic cells. They consist of ribosomal RNA and associated proteins.

They are the site of translation in both prokaryotic and eukaryotic cells.

They are made up two units which are called large sub-unit and small sub-unit.

In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.

In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.
