What is the basic flow of genetic information in all cellular life? Include in your answer a diagram that illustrates the relationships between the basic components and steps in the flow of genetic information

What will be an ideal response?


Answer: Answers and diagrams should demonstrate understanding of the central dogma of molecular biology (DNA RNA Protein) and the basic enzymes/molecules involved in each step (RNA polymerase, ribosomal proteins, rRNA, and tRNA). Answers could also explain that codons direct the order of amino acids in a protein, but the question does not explicitly ask for that information.
