WebMay 4, 2024 · All of an organism ’s genetic material, including its genes and other elements that control the activity of those genes, is its genome. An organism’s entire genome is found in nearly all of its cells. In human, plant, and animal cells, the genome is housed in a structure called the nucleus. WebA chromosome is made up of protein and deoxyribonucleic acid, or DNA, which is the substance that determines an organism’s inherited traits—for example, eye color in animals and flower color in plants. A gene is a segment of DNA that controls a specific trait. Each chromosome contains many genes.
WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ...
