Mitosis, the process where cell division takes place is a very complicated and important process. Mitosis, which takes place in the cell nucleus, consists of many steps; these steps in turn, have several parts to them. The main steps in mitosis are: interphase, prophase, metaphase...
Types of angiotensin II receptors
By: Alicia M Prater PhD
The angiotensin II receptors are cell surface proteins present in a number of tissues. The receptors bind angiotensin II, the active peptide in the renin-angiotensin system, also known as the RAS. There are four known types of angiotensin II receptor, which were first classified based...
Similarities of prokaryotic andeukaryotic cells
By: Tami Port MS
A cell is the basic unit of structure and function for all life, and although there are many different forms of specialized cells (such as neurons, epithelial cells, muscle cells, etc.), at the most basic level cell biology there are only two true cell...
The differences between prokaryotic and eukaryotic cells
By: Tami Port MS
Cells are the basic units of life, and although there are many different forms of specialized cells, there are only two true types of cells — prokaryotes and eukaryotes.The differences between these two cell types include the following.* Cell Walls – Although most...
External structures of prokaryotic cells
By: Tami Port MS
Many prokaryotes have distinct appendages, delicate strands made of protein, that extend beyond the surface of the cell. Whip-like flagella enable some bacteria to move about, shorter extensions, called fimbriae, enable bacteria to adhere to surfaces and, for pathogenic (bad guy) bacteria, allow them to...
What are bacterial fimbriae?
By: Tami Port MS
Many bacteria, particularly those with Gram- cell wall structure, have external appendages; delicate strands of protein that extend beyond the surface of the cell. These external structures of bacteria can come in many forms. Long, thin flagella are used by some bacteria to move about...
Prokaryotic Microbe Cell Biology
By: Joshua Horn - 257112
Prokaryotes are a varied type of organism that can be found in every niche that exists worldwide. They are simply organisms that lack any membrane bound organelles in their cellular structure. They are contrasted to eukaryotes, which feature a true nucleus and membrane bound organelles...

The cytoskeleton in human cells forms the backbone of all cells found in eukaryotes. This cytoskeleton helps the cell to maintain its shape, helps to protect the cell, functions in intracellular transport and allows for the cell to move using either a flagella or cilia...
How gametes are created in the process of meiosis
By: Joshua Horn - 257112
Through meiosis, sexually reproducing organisms create gametes that house half of their genetic material. These gametes are then combined with the gametes of their mate to form the first cell of the offspring organism. It allows for stable reproduction producing two half sets of the...

Meiosis is the process by which sexually reproducing organisms create gametes that house half of their genetic material, to be combined with the genetic material of a mate. It allows for stable reproduction producing two half sets of the genome so that, through reproduction, a...
