Ribosome

Ribosome

Objective

• Explore the function of Ribosome

• Describe the function of the cell

• Study protein synthesis

• And distinguish between RNA and DNA

What are Ribosomes?

Ribosomes are like tiny factories in the cell. They make proteins that perform all sorts of functions for the cell's operation.

Ribosomes can be found in the cytoplasm or attached to a membrane.

Ribosomes purpose

• The main job of the ribosome is to make proteins for the cell.

  
  

• There can be hundreds of proteins that need to be made for the cell, so the ribosome needs specific instructions on how to make each protein

  
  

• These instructions come from the nucleus in the form of messenger RNA

What is the main function of ribosome ?

Ribosome Structure

• The ribosome has two main components called the large subunit and the small subunit.

• These two units come together when the ribosome is ready to make a new protein

• Both of the sub-units consist of strands of RNA and various proteins.

Protein Synthesis

• The main job of the ribosome is to make proteins for the cell

• There can be hundreds of proteins that need to be made for the cell, so the ribosome needs specific instructions on how to make each protein

• These instructions come from the nucleus in the form of messenger RNA
