According to the World Health Organization, biohazards occur every day throughout the world. As a matter of fact, “bacteria, viruses and parasites are responsible for the bulk of the 18.4 million deaths worldwide from communicable diseases in 2004,” (WHO) essentially making them a threat to humankind. Therefore, alarming people about the danger of these microscopic organisms is extremely important. In fact, there is a picture called “Warning-Biohazard” that is on Iowa State University’s website…

In the Hallmarks of cancer, the cancer cells are that which, when in the body, tries to avoid being killed off (apoptosis). Once a cell does happen to die, the cell membrane shrinks down and the cell to the next of it will devour the rest of the pre existing cell. When a cancer cell that make up a tumor needs to grow large, the tumor then depends on the blood vessels to nourish upon. The tumor rely on the nutrients as such; oxygen, glucose, and amino acids. The waste that expels out of the cell…

The RNA World: The Implications and Problems it Presents Brandon Gutierrez Abstract The origin of life on Earth is a difficult topic to analyze with the limited data available in modern science. Many hypothesis have been suggested to explain how life may have arisen from an abiotic environment, but the topic is still far from fully understood. One generally accepted hypothesis to explain the origin of life involves an RNA world in which RNA was synthesized abiotically and carried out both the…

This property distinguishes them from small, monomeric G proteins. The guanine nucleotide-binding site is present on the G subunit. Replacement of GDP by GTP, following interaction with an activated GPCR, results in a conformational change in the G subunit. In its GTP-bound conformation, the G subunit has a low affinity for G…

Pathophysiology: Proteus syndrome is caused by an activating somatic mosaic mutation in AKT1, a gene which encodes the well-studied serine/threonine kinase PKB/Akt .1,2 Akt is the key mediator of the PI3K signaling pathway. In response to a growth signal (e.g. IGF, EGF) and the autophosphorylation of a receptor tyrosine kinase, PI3K is recruited and activated, generating PIP¬3 molecules at the lipid membrane. These partially activate Akt and also activate PDK1/2, which complete the Akt…

the movie. All of the principles he would balance all of them because he treats people as individual instead of groups. He would find any possible way for each individual has justice, freedom, and personality. He treats his patients as humans not guanine…

Designer babies are the new way to bioengineer offspring, to change the different genetics of a child. Scientists will be able to eventually use transcription and translation to change the different traits like; gender, appearance, intelligence, diseases, and personality. There is much controversy on whether designer babies should exist because of ethical controversy and designer babies causing additional racism in our country. Only the wealthy will be able to have designer babies, and will…

Introduction: Prokaryotic cells are cells that do not have membrane bound organelles, such as ribosomes and include organisms such as bacteria. In contrast, eukaryotic cells contains organelles and are often more complex organisms (Karp, 2010). These cells have some similar features such as the plasma membrane and the use of ribosomes to make proteins. However, there are also significant differences between prokaryotic and eukaryotic organisms. Whilst the prokaryotic/ eukaryotic…

stress levels, and also thermoregulation (Claussen & Art, 1981). Finally, as for the chameleons, unlike other species of lizards, they have evolved two iridophores (reflective pigments) with different morphologies, upper layer can actively tune the guanine nanocrystal spacing into triangular lattice to have a quick structural colour change and the deeper layer of cells reflect near-infrared range (NIR) of light (Teyssier, Saenko, & Milinkovitch, 2015). These two different layers enable…

Epigenetics is a complex field of study that has rapidly expanded within the last three decades as DNA technology has advanced, allowing scientists to explain hereditary traits that could not be elucidated by Mendel’s laws. Through extensive study of non-Mendelian inheritance, epigenesists developed a number of mechanisms for the alteration of gene expression that occurred outside of the actual DNA sequence. In addition, changes in the epigenetic expression of DNA have lead scientists to believe…
