DNA is a set of instructions for proteins and proteins are the building blocks of your body.If some DNA is missing or not in the right order (a mutation) a protein may be made wrong or not made at all.That protein could be very important such as insulin which leads to Diabetes or a protein receptor on a cell may be the wrong shape like in cystic fibrosis.These mutations are not totally disasterous, however a big chunk of DNA gone missing will most likely result in that embryo not surviving.
Cells need DNA because it contains the instructions for making proteins, which are essential for the structure and function of cells. DNA also carries genetic information that is passed on from parent to offspring, allowing for growth, development, and the ability to respond to changes in the environment. Without DNA, cells would not be able to carry out their functions and organisms would not be able to survive.
So that the cells can function correctly. (EX- DNA dictates the function of cells in the body. Also, the cell could not carry out protein synthesis)

What cells carry DNA?
The main cells in your body that contain DNA and RNA are your skin cells. This is because skin cells hold more then the DNA to skin. The DNA in skin also tells a person's eye color, height, hair color and bone structure. RNA in any cell is used to transfer any messages from one cell to another.
Which blood cell has DNA?
All blood cells have DNA, which carries genetic information and is important for cell functions. White blood cells, red blood cells, and platelets all contain DNA, although red blood cells lose their nucleus during maturation and do not have a nucleus with DNA.
What do all cells have in common?
They all Contain DNA
All cells have DNA. The DNA of a cell can be found in the?
nucleus of the cell.
Is there a cell in humans that don't have DNA?
No. Not all cells have a nucleus, which contains nuclear DNA; but all cells have mitochondria, which have their own DNA, called mitochondrial DNA, or mDNA. In humans, the cells that lack a nucleus and therefore nuclear DNA, are mature red blood cells, but they do have mitochondria and mitochondrial DNA.
When does the cell need to copy the DNA-?
DNA ultimately controls all the cell's functions, so it is necessary to have it in all your cells. Every time your cells divide so that you can grow or repair your body, the DNA needs to duplicate so that it can be in each of your cells.
Which cells have DNA as their genetic material?
Haploid cells like sperm cells,ova,bacteria
Why do you have DNA in your cells?
You have DNA in your cell because you need DNA to be some one and you should have DNA in your nucleus
In what ways are cells similar?
All cells have DNA
When do cells need to copy their DNA?
because it need to form then them
Out of bacterial cells animal cells and plant cells which contain DNA?
Bacterial cells, animal cells, and plant cells all have DNA. DNA contains information for the cell on how to perform tasks. In plant and animal cells, DNA is contained in a nucleus, unlike bacterial cells where DNA is contained in a nucleoid.Hope this helped
Where is all of your DNA found?
in your cells
What cells carry DNA?
The main cells in your body that contain DNA and RNA are your skin cells. This is because skin cells hold more then the DNA to skin. The DNA in skin also tells a person's eye color, height, hair color and bone structure. RNA in any cell is used to transfer any messages from one cell to another.
Who has more DNA the liver or kidney?
DNA is found in all cells and therefore in all organs, however, if strand by stand of DNA is counted, then the organ with the most cells would have the most DNA.
What cells do not always have DNA?
some sex cells have 1/2 of the dna, all i could think of
What characteristics do all living things need?
the characteristics all liveing things need are DNA, cells, grow and develop, reproduction, respond to stimuli, energy.
Which blood cell has DNA?
All blood cells have DNA, which carries genetic information and is important for cell functions. White blood cells, red blood cells, and platelets all contain DNA, although red blood cells lose their nucleus during maturation and do not have a nucleus with DNA.
