Every one has different DNA, and inside the DNA are genes or genetic information passed down from your parents. The reason for the diversity of life fors however, is due to chromosome arrangements, such as humans are humans only if they have 46 chromosomes and dogs are dogs only if they have 78 chromosomes. However, not all humans and not all gogs are the same. This is because inside of the chromosomes is your DNA, and your DNA is made up of a different arrangement of nitrogen bases, which are like the letters in the alphabet which can create an almot endless ammount of words with different combinations. Just like this, the nitrogen bases can create billions of different arrangements which meens billions of different people. The nitrogen bases are arranged into the DNA in the form of a doubble helix like a tristed ladder and the nitrogen bases are the rungs of the ladder. Ever part of your DNA has a part in how you look as you grow, like a program in a computer. This is why every life form of eath is different is some way. A plant can have 216 chromosomes!
