What are ribosomes and their function?

Back

Ribosomes are non-membrane bounded organelles responsible for protein synthesis; they are found in both eukaryotes and prokaryotes.

Front

What contains all the genetic material in a cell?

Back

The nucleus contains all the genetic material.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a cell that lacks a nucleus and other membrane-bound organelles; it includes archaea and bacteria.

Front

What are the main differences between eukaryotic and prokaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is the role of DNA in the nucleus?

Back

DNA in the nucleus stores genetic information and provides instructions for the cell's functions.

Front

How do ribosomes contribute to protein synthesis?

Back

Ribosomes translate messenger RNA (mRNA) into polypeptide chains, forming proteins.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the significance of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
