DNA, Chromosome, and Genes are related. How?
You have trillions of cells in your body. You can only see them under a microscope. DNA is in Chromosomes and Genes. We have 23 sets of Chromosomes. All chromosomes have different information. DNA is made up of 4 bases, T, C, A, and G. The bases are like letters. Certain bases can only go with certain bases. T and A go together, and C and G go together. 3 bases go together to make Codons. Codons are like words. When codons come together, they make genes. Genes are like chapters in a book. 2 Genes make a Chromosome. Chromosomes are like books.
