What are genes?
Everyone has the same set of genes.. There is actually about 20,000 in all & we are 99.5 % the same. We all have about 50 million cells in our body & each one contains unique traits about our body. These are DNA :D The letters in the DNA alphabet are A T G & C.. A's always match up with T's.. G's always match up with C's.. DNA forms ladder type structures within your cells. Chromosomes are organized into short sequences called genes. Your genes decide what you look like and things like this. You inherit genes from your mommy & daddy! Cells use genes to make proteins!
