What makes DNA so important that it can be found in all cells?

What makes DNA so important that it can be found in all cells?



DNA is found inside the nucleus in all bit bacteria cells.

On what specific structures within the nucleus is the DNA found? How many of these "structures" do you have in each of your cells?What makes DNA so important that it can be found in all cells?
"Cells are the building blocks to all life" ALL living things are made up of them, non living things are made of atoms.

In a cell there are proteins, water, nutrients, energy and DNA, an animal cell is made up of

-lysosomes; clean out system, then self destruct

-ribosomes; carry proteins

-endoplasmic reticulum; transfers protein

-mitochondria; transfers energy

-golgi bodies; remove waste

-vacuoles; hold water and nutrients

- cytoplasm; jelly structure hold everything in place

-cell membrane; outer like shell to protect the cell

-nucleus; is like the brain of the cell, contains the nucleolus and produces protein

-nucleolus; contains DNA



There in only one nucleus and nucleolus per cell. There are two types of cell, one prokaryotic, the other eukaryotic



-prokaryotic; have no nucleus and nucleolus, therefore the DNA is spread out in the cell, this includes bacteria

-eukaryotic; have a nucleus and nucleolus, the DNA is contained within, this includes animals and plants.



DNA is the genetic makeup, made up of chromosomes, 46 of them, 23 from mom 23 from dad. In these chromosomes are characteristics that will define your eye color, your hair, skin color, most everything. DNA is like a rule book, it tells the cells where to move, how to grow and what to do, like the brain, where would you be without it?What makes DNA so important that it can be found in all cells?
DNA is what tells things what it is and what it is supposed to do like a computer code in a computer.
