A karyotype shows the shape, relative sizes and general structures of an organism's chromosomes. This technique, which uses special dyes and microscopes to view the chromosomes, is very useful for detecting large mutatio... More »

The threadlike structures found in a nucleus are called chromosomes. Chromosomes are found in all of the body's cells except for red blood cells, which are referred to as anuclear. They are composed of DNA that carries g... More »

The rod shaped structures in the nucleus of a cell are chromosomes. They carry genetic material in a "rod" of DNA that is bonded to various proteins in the cell nucleus. More »

The function of a cell membrane, also referred to as the plasma membrane, is to protect the structures within the cell, give shape to the cell and support its structure. More »

A normal human karyotype typically contains 23 pairs of chromosomes. Abnormalities in the number of chromosomes may result in genetic defects or serious health issues. More »

A synapsis is the pairing of two chromosomes during meiosis. This process allows for the chromosomes to crossover and genetic material is exchanged. This exchange leads to varying genetics in organisms that reproduce sex... More »

In human cell mitosis, each daughter cell will have the same number of chromosomes as the parent cell, which is 46 chromosomes. If the parent cell is diploid, it has two sets of chromosomes, or a total of 46. If it is ha... More »
