Document Summary
The backbone of the helix is made of. Four types of nitrogeneous bases are adenine, thymidine, ctyosine, and guanine, called nucleotides. Adenine always matches with thymine, cytosine always matches with guanine. Bonds have to be weak so that dna can replicate. Genes are certain segments of dna. their job is to direct the production of a specific protein. Rna is the secretary of the dna. the dna says what needs to be made, then the rna goes to the genes and tells them what to do. Nuclear dna. you have 2 copies, one from mom, and one from dad. The blueprint of life is in the nucleus of your cell. In the mitochondria is the powerhouse of the cell and it makes atp, or energy, for your body to function. It"s only from your mom, and she passes on 2-10 copies of it in each mitochondrian.
