mucolipidosis type IV” discussed the impacts of TRMPL1 on MLIV. Lysosomes are important in maintaining healthy cells, however, with the absence of lysosomal TRP channel TRPML1 then the lysosomal pH becomes more acidic because of the calcium leakage; hence, this makes lysosomes more sensitive to fusing, and due to being near exocytosis regulating secretory granules in polarized secretory cells, phagocytosis occurs between the two organelles to create a larger organelle. This enlargement fusion…

Human culture has a constant drive for perfection in all aspects of life. People are determined to achieve the best jobs, the best homes and the best form of “living”. Even if all those things are well achieved, humans are driven to strive for more. There seems to be no point where this controlling behavior will get to a stopping point. Recently, technological advancements in medical sciences have allowed potential parents to genetically “play” with preferred traits in an unborn baby. Parents…

3 Main Points: 1. The cell contains three important things. Those three things are the nucleus, mitochondria, and the ribosomes. The nucleus consists of DNA and RNA molecules which contain hereditary information that has a jurisdiction of the cell’s purpose. The mitochondria contains mtDNA distinctive influence in human developmental research. Lastly, the ribosomes are the basic necessity to the process of protein synthesis. 2. Meiosis is a process where specialized cells split and evolve,…

Walter Glannon explores several moral problems with genetic enhancement in his article “Genetic Enhancement,” published in Glannon’s book, From Genes and Future people: Philosophical Issues in Human Genetics (and later in Bioethics Principles, Issues, and Cases.) Glannon believes that “gene therapy is permissible if it is intended to ensure or restore normal functions, but it is morally illegitimate if it is aimed at enhancing functions beyond normal.” (577) Glannon, a professor of bioethics and…

In today's society, there are numerous debates on whether a serial killers, rapists, sociopaths, and illnesses in general are due to the genes of our parents or the environment we live in. Due to recent discoveries of Epigenetics, I believe that many behaviors and genes may be influenced by the environment. Epigenetics has shown that certain environmental signs can activate or deactivate certain genes that have a large impact on personality overall. However, due to the complexion of the human…

selection is known for the causes of evolution because natural selection is the process of which the environment favor the species with favorable traits that will help them survive. Scientists believes that at some point all living beings were one single cell, but throughout years it all developed into animals and humans. In the other hand, religious people, in this case Christians, believe a Superior Being created humanity and other living…

with determination because they knew that the answer was the key to life so. They began by using a model building approach to try and find out the structure of the DNA molecule. They needed how the DNA transmitted information from parents to daughter cells. They failed their first attempt but their second attempt was successful that they were celebrated for their hard work by a Nobel Price. From their success they then constructed the double helix strand model with all the nitrogenous bases…

2. Synthetic surfactants used in pharmaceuticals and their properties. 2.1 Classification of surface active agents. The widely used synthethic surfactants in pharmaceuticals are classifieds as according on their surface charges. 1.Anionic surfactants:sodium alkyl sulfonates .SDS,SLS. 2.Cationic surfactants:Quaternary ammonium chlorides (quats),pyridinium salts . 3.Zwetterionic (amphoteric) surfactants:phospholipids- Phosphatidylcholine (Lecithin). 4.Nonionic surfactants: spans( esters of…

1. Francis Crick Crick discovered the relative distances of the repetitive elements in the DNA molecule, and the dimensions of the monoclinic unit cell which indicated that the molecule was in two matching parts, running in opposite directions. He also, in collaboration with Watson discovered the material that our genes are made of and put forward the model of the double helix DNA structure which included the measurements of the angels formed by different chemical bonds. Crick in collaboration…

biology is describes the transfer of genetic information within a biological system and was first stated by Francis Crick in 1956. The central dogma is the flow of genetic information as ‘’DNA makes the RNA and RNA makes the protein.’’All biological cells with few exceptions in some follow this rule. This flow takes place through three fundamental processes: replication, transcription and translation. Central Dogma theory was modified when it was found that in some cases RNA carry the genetic…
