Cell aging and its mechanism has been a hot research topic. A large number of research results indicated that the aging degree of animals is inversely related to the mitochondrial function. The function of mitochondria is becoming weaker and weaker with the increase of aging degree [1-6]. Mitochondria generate ATP through the process of oxidative phosphorylation, simultaneously reactive oxygen species. Early researchs has proven that oxidative damage caused by reactive oxygen species is one of…
As macromolecular machines, enzymes conduct their designated work in the confined and crowded spaces inside living cells. How does a protein work in such a condition? Functions of proteins are strongly dependent on their structural stability and dynamics while the (macro) molecular interactions are arguably affected by the complexity and diversity of their environments. To date, two interrelated cellular conditions — ‘macromolecular crowding’ resulted from the effect of volume exclusion by…
1) (20 points) The Human Genome Project (HGP) – Awesome Achievement… for what? The Human Genome Project has guided the medical field and has chnaged many lives. With having the human genome project you can now look into your genetrics and find mutation sin your own geneome to find out what you have or are at risk of having. Also with human genemeing we have found areas in the gene that represent a certaint disorder and with medican we can help change the issue within the body. For example there…
Protein are the central to life because they control almost all cellular processes, including initiating most of the reactions that occur in the living thing cells. They are one of the building blocks of body tissue and also can serve as fuel source. They are naturally occurs which means that they are made by living cells, like animals, bug, fungi and even human. They can interact with one another and other biological macro mules to form complex assemblies. Some are quite rigid whereas others…
functions (Kinworthy, 5). Every system has their own limitations of what they can do. This is due to differentiation the cells within each system become specialized for specific functions (Martini, & Bartholomew, 2). If something were to happen to one of your systems, your body’s other systems could not help because their cells do not have the ability to do what the other systems cells did (Kinworthy, 5). An example of three systems that are needed for your body to be at optimal health would be…
Oh, Babies! Figure 1: Twin babies When you saw multiple on your ultra sound, what did you do? You are certainly getting more than you bargained for! Did you question whether you were seeing multiple or question your prescription? Having multiple babies, specifically twins, is perfectly normal! Twins are now on the rise; every one in thirty babies is a twin. This article helps simplify the science of twins for you, so you know exactly what is happening in your body or your wife’s body! Twins…
Albinoism 750 words Albinoism is a some what common skin deformation. This condition can be devoloped before birth and is easily identified by lack of pagment in skin, eyes, and hair. It Is a complete lack or little of pigment melanin which is what makes the skin, eyes, and hair the colors that it is. For example; a black person has darker skin because they have more pigment melanin than someone who’s orgins go back to europe. People with Albinoism have such a lack that their eyes, skin, and…
thought-out the world. The objective is to genetically engineer the perfect child using a new technology for editing DNA, called CRISPR-Cas9- or germ-line editing. One main topic covered in this article is that Scientists are currently working on cell editing, which could make it possible to correct diseased or imperfect genes and pass those genetic fixes onto future generations. As a result of these adjustments, someone who has a history of illness in their family, could have that strand…
the ribosome. Lots of cells secrete proteins into their surrounding extracellular fluid. Some cells like hormones and neurotransmitters secrete regulatory molecules. Whereas others release digestive enzymes, antibodies, or mucus. Fibroblasts secrete collagen are the whole body and other structural proteins to deliver the body with strength and hold the body together. All proteins are synthesized at cellular structures called ribosomes. When the protein is used in the cell the ribosome stays in…
and HEK 293 cell. The purification of DNA also allows the extraction and purification of plasmid DNA. According to the data that was generated by the completion of the Mini Prep, GFP DNA tends to have a higher concentration of 27.544 µg compared to NFkB DNA that has 16.950 µg. GFP DNA is considered to have properly purified because it yields a high number of concentration at the end of this process. GFP DNA successfully transfected…
