In the experiment, onion root tips are choosen to be observed under microscope. It is because the chromosomes are larger than most of the others plants. The root tips of onion are picked to observed as the root tips are the region where the cell …

Different types of bacteria in various forms are found all around us, and it is a microbiologist’s job to be able to identify these bacteria. Using various staining techniques and physiological tests, an isolated bacterium can be identified. In this experiment, a single bacterial colony …

Genetic Engineering – A Curse or a Blessing? What is geneitc engineering? Many struggle to understand the real meaning and outcrops of this complicated, highly expensinve procedure. Genetic Engineering is a direct human manipulation of an organism’s DNA structure. As intricated as it seems, it’s …

Introduction Once absorbed, active elements of vitamin D, such as calcitriol, attach themselves to intracellular receptors and then act as transcription factors so as to modulate gene expression (Holick, 2010). The vitamin D receptors are similar to thyroid hormones and steroid hormones receptors and contain …

Lectin is a protein that is commonly found in certain plants such as grains  (wheat), legumes (soybeans and peanuts), and also can be found in potato, tomato, eggplant and pepper. It is found to be toxic, especially if the food containing it is undercooked. It …

IntroductionThe Golgi setup ( GA ) , besides called Golgi organic structure or Golgi complex and found universally in both works and animate being cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered pouch called cisternae that look something like a …

The fungal species about 100 stains which were previously isolated at the laboratory of biology department king khalid university will be used in this study. Fungi will be cultured on potato dextrose agar pda medium for 7 days at 27 °c. Identification of these species …

Define metabolism: The sum of all biological chemical reactions inside a cell or organism Differences in catabolism and anabolism: Catabolism is an enzyme-regulated chemical reaction that releases energy. Complex organic compounds such as glucose, amino acids, glycerol and fatty acids are broken down into simpler …

Base pairs: always occur in a specific way – A(adenine) always pairs with T(thymine) and C(cytosine) always pairs with (G)guanine. Because of this specific base pairing, the base sequence of one DNA strand determines the base sequence of the other strand. Genetic code: the set …

The experiment shown in figure (3) was done to characterize the role of cargo protein binding domain of sec24p in protein sorting. The vesicles were generated with the Sec24L616W mutated from microsomal membranes. The number of cargo proteins were estimated by immunoblotting or by autoradiography …

Although most mutants are either impersonal or harmful they are besides the natural stuff for development. Such mutants from allelomorphs. surrogate signifiers of a given cistron that may bring forth differences in construction or map such as black. brown or blond hair in worlds. or …

Rauch, in the beginning of his article, points out several potential merits of agricultural biotechnology such production of transgenic seeds which can counteract the effects of herbicides (2003). This could facilitate no-till farming since the use of herbicides can curtail the growth of weeds. The …

The purpose of this experiment was to observe the process in which cells must partake in a respiration process called anaerobic fermentation and as the name suggests, oxygen is not required. This particular procedure, which Is catabolic meaning, it breaks down energy, can be present …

Bacterial cells are a common choice for in vivo replication of DNA of interest, and in this study, the heat shock method was employed for bacterial transformation. Plasmids, which are DNA molecules themselves, were used as expression vectors for the DNA of interest, the GAP …

Chapter 15 Signal Transduction Endocrine, paracrine , autocrine signaling, and cell-cell contact. Endocrine signaling is long distance signaling. An example would be pancreatic cells secreting insulin. Paracrine signaling is for close proximity. An example would be a nerve cell releasing neurotransmitters. In autocrine signaling the …

8 themes of biology relating to the cell membrane Science as a process: Science is a process which encompasses many methods in order to reach a final conclusion. This relates to the cell membrane because it carries out many processes to reach a final product. …

Nucleus: The nucleus is the most obvious organelle in any eukaryotic cell. It is enclosed in a double membrane and communicates with the surrounding cytosol via numerous nuclear pores. Within the nucleus is the DNA responsible for providing the cell with its unique characteristics. The …

The scientific event with the most significant implications for the future was recognition of unique differences between genome sequences of individual people (Pennisi, 2007). It is believed that about 99.5% of human DNA is exactly the same in every person. Within that 0.5% lies the …

Honors Enrichment Questions Week 3 What are chemotherapeutic drugs? Research two and explain how they work against cancer. Chemotherapeutic drugs are used during chemotherapy and are a treatment for cancer. Leustatin- used for hairy cell leukemia, chronic lymphocytic leukemia, and non-Hodgkin’s lymphomas. It is an …
