5 True/False questions
Apoptosis → Programmed cell death. An orderly process by which cells self-destruct in an orderly fashion after a certain number of cell divisions, or if they cannot repair DNA damage.
Central dogma → The way in which the 64 possible base triplets map onto the 20 amino acids that are used in polypeptide chains.
Morphogen → Characteristic coded for by one gene.
Proto-oncogene → Genes that control the development of the body plan of an organism.
Sexual reproduction → Production of new organisms involving fusion of nuclei from male and female gametes, usually from unrelated individuals. Increases genetic variation in the population.
