Document Summary
Information flows in one way: dna is transcribed into rna and its translation into protein, dna must be replicated before it is transcribed into rna. People, bacteria and viruses all have the same genetic material, however viruses may have rna as genetic material. Deoxyribonucleic acid (dna) and ribonucleic acid (rna) = genetic material. Consists of a nitrogenous base attached to a sugar (dna or rna, depends on the sugar) bound together with phosphate that forms the backbone. Eukaryotic organisms have a nuclei within cells to hold dna while prokaryotes do not have dna separated from the cell contents. Viruses may use dna or rna as their genetic material, however require host cells to function and replicate within; will begin to hijack the cell in order to multiple. Viruses can effect both prokaryotic and eukaryotic cells. If a virus infects a bacterial cell, it will be called a bacteriophage.
