Chapter 1:How a person gets down syndrome

        Every person has 47 chromosomes which means the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. in each cell divitore called nondisjunction. This leaves the sperm or egg wan an extra copy of chromosome 21 before the person being pregnant with a child.

Chapter 2: How does the person know they have Down syndrome

Some of the ways you can tell you have down syndrome are if you have a flat looking face. If you have a small head or small ears. Do you have a short neck or a tongue that sticks out of your mouth? Do your eyes tilt up wards? And lastly are you shorter than usual children? Now just because you may have small ears or be smaller than other children doesn't mean you have down syndrome. I have friends that are shorter than usual kids and have small ears but they DON'T have down syndrome. So if you want the final notes on if you have down syndrome you should go to the doctors.

Chapter 3: Is there away down syndrome can be cured, or prevented???

No, down syndrome can't be cured or prevented because it's not an illness or a dresses that once you have it you can stop it. You are born with down syndrome in your mother's womb. If you have down syndrome and you have a child they will more than likely get down syndrome to because it's caused by genes.
