The cell cycle is a sequence of events in the life of a cell, including cell division. Cell division distributes identical sets of chromosomes to daughter cells. This process is used for reproduction, growth, and repair in the body. The cell cycle can be broken …

The advances in the understanding of nature in terms of scientific knowledge has been tremendous especially since the mid-1950’s with the discovery of the DNA structure, which precipitated more advances in molecular biology, genetics, and biochemistry.  However, in the end of the 20th century until …

Adhesion molecules or receptor play key role in many processes involving cellular immunity that included haematopoiesis, migration, activation and finally apoptosis. They are mainly surface glycoproteins and variation among them is mainly due to different pattern of glycosylation. Adhesion molecules play a central role in …

3D bioprinting is one of the most anticipating and promising technological advancements of all time. According to the US National Library of Medicine, 3D bioprinting is “a manufacturing method in which objects are made by fusing or depositing materials—such as plastic, metal, ceramics, powders, liquids, …

, the hilarious star of classics such as Blazing Saddles, Willy Wonka & the Chocolate Factory and Young Frankenstein, died today at the age of 83. The cause of death was complications from , family members say. , who directed Wilder in some of his …

Current researches are optimistic on the potentials of nanotechnology as the latest technological wonders with both environmental soundness and promise for health applications. Its advent has created promising application in various areas of human endeavors. It has made impression in the areas of novel foods, …

Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli …

This abstract is related to a seminar delivered by Dr. Platt sing Isolation of Mesenchymal root cells from kids ‘s dentitions and geographic expedition of their function in tissue fix. The seminar provided a comprehensive overview of root cells before concentrating on Mesenchymal root cells …

Insulin, an endocrine hormone, is one of the most well-studied proteins synthesized by the human body. Its relatively simple structure and short amino acid sequence have made it a useful model for many protein studies. It is synthesized in beta cells of the pancreas through …

EXECUTIVE SUMMARY Biodel’s use of biotechnology expertise in the three prime areas of Cell Biology, Molecular Biology, and Immunodiagnostics has led their company into some great opportunities. Biodel created a synthetic serum to …

Introduction Literature It is highly expressed in pain-sensing neurons which are of two types, the nociceptive dorsal root ganglion (DRG) neurons, and sympathetic ganglion neurons, which are parts of the autonomic (involuntary) nervous system (Cox et al, 2006). In human’s mutation in SCN9A cause three …

The Evolution and Mechanism of Immunological Memory and its Impact on Immunology Research. Recently, the Center for Disease and Control reported that it has discovered a super bug, a bacteria, that has the capability of resisting almost any antibiotic known to human. In addition to …

Policy Topic: Stem Cell Research Health Care Policy: The Past and the Future: HCS/455 A very controversial subject in the United States has been Stem Cell research. The United States has a very complicated legal and political history when Stem Cell laws and policies come …

Cellular Respiration Study Guide 1. What is cellular respiration? Cellular respiration is the process by which cells get their energy from food. It is a pathway where ATP is produced from the working cells. 2. What are the raw materials for cellular respiration? The raw …

Thus, influenza vaccine development and deployment is a critical part of pandemic influenza preparedness. Most resource-constrained countries do not have the means for accessing seasonal influenza vaccines and may face the same challenge during an influenza pandemic. There is therefore a need for these countries …

The LIEU gene Is a linear fragment that does not notation an Autonomous Replication Sequence, so it could not replicate on its own and needed to be integrated by homologous recombination. The TRIP gene was a circular plasmid that contained an EARS, which allowed for …

Gene Splicing Lab Question #1: DNA is made up of two separate strands of base sequences. The same sequence is found on both strands, but running in opposite directions. What word describes this characteristic? Palindrome Question #2: What does the term “sticky ends” refer to …

Introduction Bacteriophage which is also known as bacteria eater refers to viruses that infect bacteria.Bacteriophages are known to only replicate within host cells and must attach to a specific receptor on the surface of a bacteria cell to initiate infection. The contact between the phage …

A taxonomic method that identifies the species of an organism by using a small genetic marker in the mitochondrial DNA of the organism is DNA bar coding. The mitochondrion of most eukaryotes contains the mitochondrial DNA, and the rate of mutations is faster that are …
