answer. The word autophagy is derived from the Greek words auto- and phagy- meaning self-eating. So cellular autophagy is a cell eating itself, also known as Autophagocytosis. Autophagy is a normal physiological process in which cells destroy organelles that are dysfunctional or no longer useful. This paper will cover the processes of autophagy, the function it has in the cell, the significance the process has to cellular homeostasis, and lastly; the how it affects cancer. The Process of Autophagy

Genetic Engineering? No Way The future of the human race is in your hands. Though it may not feel that way in your everyday routines, the decisions you make will distinctively impact your children’s live, their children’s lives, etc. Genetic engineering is sparking questions among the human race whether or not it is the next step. Creating a test tube baby I in order for parents to conceive a child is one thing but genetically modifying the human race is against human nature. Genetic engineering

properties of the membrane of the zona pellucida typically the layer found outside the plasma membrane. The protease grinds up the proteins and function as a receptor in binding a sperm (i.e. ZP3 glycoproteins and ZP2) as well as the ones that adhere the cell membrane to the vitelline envelope. The secreted molecules consist of

contain a protein named beta-lacto globulin. This is because many infants are allergic to this protein; in fact two to three percent are allergic. So these scientists have used the scientific techniques of ribonucleic acid interference and somatic cell nuclear transfer cloning to produce this cow without the protein, however there are many implications. One of the techniques used to produce daisy the cow was ribonucleic acid interference causing gene knockdown. Ribonucleic acid interference is a

more children, all of whom died from due complications before reaching age two. Years passed before the couple learned that their suffering originated from mitochondrial defects present in Sharon’s cells. Mitochondria, dubbed the ‘powerhouse of the cell’, are a type of organelle present in most human cells. Their primary function is to generate Adenosine Triphosphate (ATP), the cell’s principal source of chemical energy. Unlike most other organelles, mitochondria store their own set of genetic material

levels of specific trace metals have been suggested to contribute to the abnormal cellular phenotype, as well as the progressive cell degeneration associated with TRPML1 dysfunction4. The permeability of Zn2+ to TRPML1 suggests that this ion channel may play a role in Zn2+ regulation. A recent investigation of cytoplasmic Zn2+ accumulation in TRPML1 dysfunctional cells suggests the possibility that this protein may normally function to transfer Zn2+ from the lysosome to the cytoplasm5.

World changing, revolutionary, and mind-blowing is what this world demands and rotates around by an item called technology. Technology is flourishing and is altering the world as time passes by. Articles support this by using evidence and scientific reasons. Scientific advancements have many purposes to it such as helping the world, finding out new things or socializing with others. Although technology is a great thing, it has many cons to it. Technology is a dangerous resource in the world that

Numerous sensitization campaigns have been launched, all over the world, with the aim of promoting awareness of the rising cases of ecological destruction. These campaigns have not only targeted human activities but also business operations. Shaw (22), highlights the major environmental challenges faced in the modern world; most notoriously, water and air pollution, which he says, kills crops and vegetation, damages the ozone layer and threatens people’s lives and health. Businesses play a massive

employ a technique called somatic cell nuclear transfer,t involves removing the nucleus from an egg and replacing it with the nucleus from a somatic cell (a regular body cell, such as a skin cell), which provides a full complement of 46 chromosomes.The egg is then stimulated and, if successful, begins dividing as a new organism at the earliest (embryonic) developmental stages. This new individual is genetically (virtually) identical to the person from whom the somatic cell was taken. It is a human clone

diabetes and various other diseases. Grown up in a family of medical professionals, the curiosity to explore various life processes was not only acquired but also inherent. I want to take a leap forward of what my parents and grandparents practice and ‘Cell and Molecular Physiology’ or ‘Immunology’ as major will surely make me accomplish in achieving my aim of life. As a small child, I had seen the agony of patients and limitations of medical profession in dealing with various illnesses. I had innumerable
