T cell

Cells are the BASIC function of life on Earth. They are the fundamental unit of all living things. The cell is the smallest structure in the human body and has all the properties of be alive and being it 's own living thing and stem cells are the direct result of cells being their own living thing. The stem cell is stated to be “unspecialized cells that are thought to be able to reproduce themselves indefinitely and, under the right conditions, to develop into mature cells, e.g., nerve, skin,…

A receptor is a molecule usually found on the surface of the cell and receiving signals (chemical or hormonal) from outside the cell. Receptors belong to class of proteins. Binding of some substance to the receptor brings about changes that direct the actions of cell containing receptor. Ligand is the molecule that binds to the receptor and it can be a peptide, a hormone, neurotransmitter, drug or a toxin etc. Each receptor possesses two functional domains: recognition domain that binds the…

(v-SNARE) and a target membrane (t-SNARE) with the aid of NSF, SNAPs and other yet unknown proteins bring the v-SNARE in close proximity to the t-SNARE facilitating membrane fusion (Sollner et al., 1993). It is now widely accepted that SNAREs serve as the core machineries necessary for vesicle targeting and fusion but are regulated by proteins like Sec1/MUNC18, Rab Ypt GTPases and others that binds to them (Rothman, 1994, Bonifacino and…

efficiently change the internal organization of the cell, and capture organelles through the cytosol. Intermediate filaments are made up of the protein keratin. Their primary function is to strengthen the internal structure of a cell. Microfilaments are the smallest among the three cytoskeletal filaments. They consist of protein actin. Microfilaments are dynamic structures that can rapidly disassemble or assemble themselves, and thus microfilaments enable the cell to move efficiently. Cilia and…

something through senses. From the Aristotle Introductory Reading, “(Chapter 5, 416b32). Perception occurs by us being moved and affected.” Plants don 't have perception since they are static and they…

Genetic Engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. With this new, rapidly growing, technology we are now able to do things that we once thought were impossible. In Ethics and the New Genetics, the Dalai Lama addresses problems that we need to consider as we continue to explore this microscopic world that we have…

In the case of a missing limb, the scientists would take stem cells from the patient and us it for the base of the new limb. If Humans mastered cloning then they could use that technology and the patient’s stem cells to construct a new arm, leg, ear, or whatever was missing without worrying too much about the patient’s body rejecting the foreign limb. In the case of organs the process would…

The mitochondria is one of the most interesting components of the eukaryotic cell. Endosymbiosis is the term modern scientists use for how the mitochondria came to be. Symbiosis translates from Greek to English as “living” “together.” Constrantin Mereschkowsky, known as the founding father of the theory of endosymbiosis, was one of people who started the concept of endosymbiosis, although he had called it “symbiogenesis,” defining it as: “the origin of organisms through the combination and…

to change into these protective suits so we would be kept safe from any harmful substances. We were all told that we would be put into two groups the A and the B group. We would all be put into a Eukaryotic Cell if the machine worked to get a closer look at the organelles in a Eukaryotic Cell. I was put into the A group along with another girl who looked about 16. The B group had a boy who looked about 14 and a girl who looked about 15. I guess the age varied between all of us because I am 17.…
