Neurons are the cells specialized to receive, conduct, and transmit signal to the nervous system. The development of neurons starts early during the embryogenesis. After the fusion of sperm and egg, zygote is formed which is further divided to form blastula eventually leading to gastrula stage of development. Gastrulation begins as invagination of cells in the embryo leading to the formation of three germ layers. Formation of notochord from the mesodermal layer marks the beginning of neurulation…

Cells are the basic building block of life, it plays a vital role in transferring human language called DNA from generation to generation. DNA stands for Deoxyribose Nucleic Acids, it contains genetic information for our cells. It contains all the essential elements of the universe, in such precise quantity, that it sustains life. Our DNA, is able to instruct the cell in terms of which protein they have to make.Following the instructions, the protein created determines the cell…

Back in 1878 lung cancer was almost a rare disease; it was only one percent of all the different types of cancer. Scientists thought, in later years once the idea that cells split, reformed, and split again, that the reason there was little talk of cancer in the ancient world was because people did not live long enough. But in the EMPEROR OF ALL MALADIES by Siddhartha Mukherjee traces the history of the disease from 2500BCE to the present. By the early 1900s cancer seemed to be increasing. Or…

students are going to sitting in front of a computer for hours and hours playing games and learning a topic. I do not see this to be the case, in almost any situation. Serious games are going to be extremely focused on a topic, such as learning mitosis. In addition, the play time will quite short. Serious games are a supplemental to lecture, books, and so forth. They a tool help solidify difficult topics to learn, such as electromagnetic induction. Too many games, teach very simple topics like…

meiosis. For ova, only one functional gamete is produced during meiosis, along with three polar bodies. F. Number of Germ Cells Available to Produce Gametes - male's possess an unlimited supply of germ cells. Spermatogonia divide continuously by mitosis throughout the person's lifetime. Females possess a limited a limited number of stem cells that are converted to ova in prophase |. They possess roughly two million at birth, but only approximately 400,000 remain once the female has reached…

Prokaryotes, specifically bacteria, have feedback regulatory mechanisms like eukaryotes do to make tryptophan. Tryptophan is one of the 20 amino acids which we all need. If there is a lot of tryptophan made, then you turn off the enzymes that are involved in tryptophan synthesis by binding and causing a change in shape of the enzyme (negative feedback). In addition, repressors are proteins that bind to the operator and prevents expression of the gene. However, the repressor is unable to bind to…

Polio? Rather say dinosaurs. It is scary, dangerous, and extinct. What is this disease? Why only the parents of new born sweat for its vaccine for the tiny citizens of the Earth if it is eradicated? You are one of the two. One who knows about the polio because you lived in the time when it showed its colors and shook the world or that you are the one whose parents knows well enough, thus your body already bears the ‘protection’ and therefore vaccine. Let’s tell more than your queries about…

this cancer is ultimately altered because of these abnormal cells. This means instead of normal cells differentiating and becoming specialist cells at the end of the cycle, the cancer cells never die and continue to grow and infect the body during mitosis. There are many ways that leukemia affects the body and there are many diseases that can be…

Genetic Disorders are medical conditions that are caused by an error in a person’s genes. Some genetic disorders appear as birth defects, while others do not become distinct until later in life. They can rage from terminal to mild. Scientists have distinguished more that 9,000 genetic disorders, some of which are exceptionally rare while others are common. One such genetic disorder is Philadelphia Translocation, a possibly terminal and relatively rare genetic disorder (fewer than 200,000 people…
