-If one protein malfunctions it can send a wave of dramatic effects on the body. One of these effects is mental retardation. The proteins are responsible for making the DNA codes, and in the case of mental retardation they have made a faulty enzyme in the code.
Another faulty code the proteins can produce can make a person albino.
A ribosome is a particle that is composed of protein and RNA and is the site of protein synthesis. It is composed of two subunits that work together to make proteins according to the RNA.
They are found in both prokaryotic and eukaryotic cells. (plants animals bacteria)
Inside the Cells:
-Messages from the nucleus are sent into the endoplasmic reticulum where the ribosomes are located.
The proteins are transferred to the golgi apparatus where the proteins are modified.
Ribosomes work along with most of the organelles because they make the proteins that they need to perform.
Ribosomes form proteins which act like the bricks to build a house.
They take orders from the RNA and Nucleus just as workers have to pay attention to the building plans and instructions from a forman.
The proteins made by Ribosomes act as a barrier from diseases just as a house is used to protect people from weather and diseases.
The Source of All Knowledge in the Cell
Chromatin is composed of DNA, proteins called histones and other assorted components such as transcription factors. Chromatin contains the genetic information that guides the function of the cell and the creation of proteins.
DNA- Stores the genetic information to produce proteins.
Histones- Compacts the DNA into tight groups, saving space.
Chromatin is found in animal, plant, fungi and protist cells.
Chromatin is not found in prokaryotic cells. DNA is 'naked' and not packaged with any proteins, therefore classifying it as simply DNA not chromatin.
Chromatin is opened and closed by chromatin remodeling ATPases. A misfunction of these cause several diseases including:
- embryonic lethality
-cause mutations that lead to cancer
Chromatin is like a staple holding a stack of important documents together.
-It binds the DNA together to save space
-stores the important information.
-it helps keep the DNA organized and allows it to function properly.
Chromatin works with other nuclear organelles by entering and exiting the nuclear membrane through nuclear pores. Chromatin also works with ribosomes by giving them genetic info to produce.
The Nucleolus is found in all types of Eukaryotic cells such as plant, animal, protist and fungi cells.
It is found at the heart of the cell, in the center of the nucleolus.
A malfunctioning nucleolus is known to cause neurodegenerative disorders such as Huntington's and Alzheimer's, and could also be a cause of Parkinson's disease as well.
A nucleolus is like a manager of the cell which acts as the factory.
The ribosomes are the factory workers that constantly take orders from the nucleolus.
The nucleolus is constantly "hiring and training" new ribosomes just like new factory workers.
The nucleolus and its counter part the nucleus work with the entirety of the cell, and all the organelles present, however nucleolus mainly works with the DNA and RNA brought into the nucleus to make Ribosomes.
