Components of the endomembrane system: nuclear envelope, endoplasmic reticulum, golgi apparatus, lysosomes, vacuoles, plasma membrane. Mitosis is conventionally divided into five phases: prophase, prometaphase, metaphase, anaphase, telophase. Advantages of pea plants for genetic study: there are many varieties with distinct heritable features, or characters (such as flower color); character variants (such as purple or white flowers) are called traits, mating can be controlled, each flower has sperm producing organs (stamens) and an egg producing organ (carpel, cross pollination (fertilization between different plants) involves dusting one plant with pollen from another. Overview: life"s operating instructions: in 1953, james watson and francis crick introduced an elegant double helical model for the structure of deoxyribonucleic acid, or dna, dna, the substance of inheritance, is the most celebrated molecule of our time, hereditary information is encoded in dna and reproduced in all cells of the body, this dna program directs the development of biochemical, anatomical, physiological, and (to some extent) behavioral traits.
