memories; cells are the absolute smallest building blocks of life, each manifesting a sophisticated design. Broadly speaking, the cells are divided in eukaryotes that contain membrane-bound organelles; and prokaryotes that do not (Diffen, 2007)—in short, prokaryotes are both simpler and smaller. The DNA is the molecule that possesses all the “blueprints” an organism requires at every stage of its life. Thus, replicating the DNA ensures that the design will be passed down to every newly formed…

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…

Cell biology 1. A cell is eukaryotic because  Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment.  Eukaryotic cell has an organized nucleus with a nuclear envelop.  Has membrane bound organelles  Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes.…

Genetics is the study of genes, genetic variation, and hereditary in living organisms. In DNA A always pairs with T. DNA is the blueprint of life. Humans have 46 chromosomes. Our entire DNA sequence is is called a genome. The average gene is 10,000 to 15,000 bases long. DNA can be extracted from many different types of samples: blood, cheek cells, urine. Alleles are forms of of the same gene with small differences in their sequence of DNA bases. Genes are made up of DNA. There are about 20,000…

within a cell, they can be expressed in response to external stimuli. This external stimuli can be sub lethal heat shock (SLHS) hence the name heat shock proteins (Baneyx, F. 2008), this stimulus causes more of the proteins to be produced (Pugsley, A. 1989). In addition to being expressed due to SLHS they can also be expressed in response to amino acid analogs, heavy metals…

many other problems with the lung, pancreas, and many other parts in your body. The disease is caused by a defective gene called the CFTR gene. These genes code to produce CFTR proteins which are used to transport water and particles into or out of cells. This helps maintain a healthy balance of water and salt in your body. However in people with Cystic Fibrosis, these genes cannot properly code proteins, causing very thick mucus. This can cause blockage in the lungs and digestive system. Cystic…

Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used to…

key for the development and survival of a fetus/embryo. 2. Leydig cells • Leydig cells form and secrete testosterone. The testosterone is secreted in response to the lutenising hormone. Spermatozoa production is promoted by the testosterone secreted. The testosterone being secreted by the Leydig cells are important for the formation of secondary characteristics of the male. 3. The different pancreatic cells • One of the pancreatic cells is the exocrine gland. The exocrine gland secretes out…

hypersensitivity response to sequestered living, dying or dead ova, that are trapped in tissues during the peri-intestinal migration or after embolization in the liver. Soluble egg antigen (SEA) and proteolytic enzymes released by ova provoke granulomatous cell-mediated immune response, with recruitment of eosinophils, granuloma formation and liver fibrosis (Cheever et al., 2000; Wynn et al., 2004). In schistosomiasis, Th2-type cytokine production becomes predominant eight weeks post infection,…

Cell phones have always been a hot topic with students, parents and faculty staff. Due to the many complications in how things can go bad, many people steer away from the topic. Although students are always cheering on the idea due to the many other school systems pro for cell phones during school. With cell phones coming a long way from only a few particular people to any everyday person having one. With the more use of phones, problems have arisen from that. Cell phones at school have many…
