continuously regulated by the cells nucleus in the regulation of proteins. However‚ this long coding process has to start somewhere. As I said earlier this function is carried out by a cells nucleus where membranes regulate the function of what enter and leaves the cells through a wide range of mechanisms. On the outside of the membrane‚ certain receptors are triggered to certain proteins inside the cells cytoplasm. A certain receptor is made that enters the cells nucleus reacting with the DNA‚ in desire

Animal cells are distinct from plant cells. Animal cells lack a cell wall (cellulose) which allows the animal to move without breaking it’s cells apart. When you break a piece of celery‚ the noise It has a nucleus‚ a cytoplasm and a cell membrane. http://wiki.answers.com/Q/What_are_some_animal_cel... What are facts about on animal cells? theyt have no cell wall. they have a nucleus and nucleolus. http://wiki.answers.com/Q/What_are_facts_about_on_... What are some facts on an animal cell

Progeria Progeria‚ also known as HGPS (Hutchinson-Gilford Progeria Syndrome)‚ is a very rare genetic condition. The word Progeria comes from the Greek “progeros” meaning ’prematurely old’. HGPS was named after Dr. Jonathan Hutchinson‚ who first described the disease in 1886‚ and Dr. Hastings Gilford who also discovered it in 1904 (Nordqvist‚ C. (2015‚ April 08). The most frequent type of progeria syndrome is Hutchinson-Gilford progeria syndrome. It’s a rare and terminal genetic disorder. Wiedemann-Rautenstrauch

Cell Theory - Biology Speech on Cell Theory. Cells are the "building blocks" of the body. A human is made of millions of cells‚ which are adapted for different functions. They are composed mainly of a cell membrane‚ cytoplasm‚ vacuole(s) and a nucleus. They are the foundations of all living organisms‚ making them probably cells extremely significant when it comes to biology. They are one of the foundations of biology itself. The Cell Theory is a theory that has been composed‚ changed and altered

biology‚ cell theory is a scientific theory that describes the properties of cells‚ which are the basic unit of structure in all organisms and also the basic unit of reproduction. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory is one of the foundations of biology.The observations of Hooke‚ Leeuwenhoek‚ Schleiden‚ Schwann‚ Virchow‚ and others led to the development of the cell theory

of cells and their ultra structure The cell is the basic unit of life. Each cell can be regarded as a metabolic compartment‚ a separate place where the chemical processes of that cell occur. Cells are often designed to perform a particular function. Depending on that function‚ each cell type has an internal structure that suits it for its job. This is known as the ultrastructure of the cell. There are different types of cells inside the human body. They are the epithelial cells‚ muscle cells‚ nerve

In an eukaryotic cell‚ DNA is tightly packaged into the nucleus. For a human cell‚ DNA measures approximately 2 meters‚ with its diameter being 2 nm. The total length of DNA present in one adult human is nearly 2.0 × 1013 meters‚ which is equivalent to nearly 70 trips from the earth to the sun and back. Since the size of the nucleus in human cell is about 6 μm‚ DNA should be tightly packaged to fit into it. At the same time‚ it should be easily accessible to express the genetic information. Inside

Difference between the Gene Regulation in Prokaryotes and Eukaryotes Gene regulation is important for all cells to be able to control gene repression and the amount of proteins produced by those genes. It helps to make sure the cell uses resources efficiently and express the right genes under the right conditions. Gene regulation can be found in both prokaryotic and eukaryotic cells. The methods of regulation differ between the two groups. Prokaryotic regulation mostly occurs by enzymes interacting
