DNA and RNA have the same structure.
DNA is made of two strands that twist into a double helix.
Guanine forms hydrogen bonds with adenine.
Thymine forms hydrogen bonds with cytosine.
Genes are compose of protein molecules
DNA and proteins are actually the same molecules located in different parts of the cells.
Bacteria injects their DNA into the cytoplasm of bacteriophages.
DNA is the molecule that stores genetic information in the cells.
