sugar, and a nitrogenous base.
What is the significance of the central dogma of molecular biology?
✔✔ The central dogma describes the flow of genetic information from DNA to RNA to protein,
explaining how genetic information is translated into cellular functions.
What are the stages of the cell cycle, and what happens during each stage?
✔✔ The cell cycle consists of interphase (where the cell grows and DNA replicates), mitosis
(where the cell divides), and cytokinesis (where the cytoplasm divides, resulting in two daughter
cells).
What is Biology? ✔✔Study of life; encompasses everything
