Mitosis occurs in every single cell that makes up the entire body. It occurs in the tissues and organs to help replace cells that have been lost as a result of normal wear and tear on the body.Know More
Mitosis is the replication of a single cell into two identical daughter cells. The original cell becomes obsolete, making the process a simple replication of a single cell. It is used in all areas of the body, but is especially important in the areas that need to have constant regeneration of cells. The skin is an example of an organ that has constant mitosis occurring due to a higher rate of cell loss as a result of environmental factors.
The DNA, or deoxyribonucleic acid, that is composed in the cells is exactly the same throughout the body. The DNA makes up what a person is and must not deviate from the original copies that were made when the person was being developed in utero. When mitosis occurs, the DNA is taken from the cell and is copied exactly how it appeared in the original cell. This process can continue for as long as there is enough energy for mitosis to take place. The DNA will constantly be replicated and will remain the same.Learn more about Biology
Mitosis and meiosis are similar in that they are both forms of cellular reproduction, and they both, consequently, produce daughter cells. Both processes also use the same four steps: prophase, metaphase, anaphase and telophase.Full Answer >
In biology, dynamic equilibrium refers to a steady state of any biological element or system (such as a single cell, or an organ, for example) that has a higher level of energy than it's surroundings and thus requires work or activity to maintain.Full Answer >
A unicellular organism is any life form that is composed of a single cell; they live and carry out all life processes as a single cell. Based on their complexity, unicellular organisms can be placed in one of two categories: eukaryote and prokaryote. Most unicellular organisms are microscopic, but some are visible to the naked eye.Full Answer >
Multicellular organisms may evolve into large and complex beings, but they all begin as a single cell and pass through several defined stages of development. All beings, from small plants and insects to large elephants, giraffes and even humans, begin as single, simple cells, called fertilized eggs.Full Answer >
