Case study - Essay Example Human genome is responsible for carrying hereditary information. In human, the structure is known as deoxyribonucleic acid (DNA). The structure carries all the human genes. There are four chemical bases found in the DNA (EDinformatics 1999). They include adenine (A), thymine (T), cytosine (C), and guanine (G) (EDinformatics 1999). Covalent bonds of phosphodiester join the bases together (Makalowski 2001). The bond helps in alignment of bases in specific pairs. Moreover, the structure exhibits a double helical organization. The organization is because of hydrogen bonding between the base pairs (EDinformatics 1999). The hydrogen bond helps in linkage of one complementary strand to the other (EDinformatics 1999). In human, the human genome is stored on 23 pair’s chromosomes (EDinformatics 1999). In these pairs, 22 are autosomal chromosome pairs while the rest is involved in determining sex (EDinformatics 1999). In human, there is a way in which genes are arranged in a genome. For example, they may be in the same (tail to the head) or opposite orientation (head to the head or tail to tail) (Makalowski 2001). The majority of human genomes account for non-exonic sequences (Makalowski 2001). However, a number of genes occupy the same genomic space. In addition, there is a tremendous difference in the human genome. Scientists have shown the difference to be occurring in millions of locations. In these locations, the single base DNA differences (SNPs) takes place in human (EDinformatics 1999). The resulting variation has led to exploitation by various researchers on the use in health screening. On the other hand, there has been interest in human mitochondrial genome (EDinformatics 1999). The genome has been shown to play a significant role in mitochondrial diseases (EDinformatics 1999). The understanding of genetic variation has an immense implication on the field of medicine. In fact, it has generated a vast potential in understanding and promoting

Network Technology and Network Administration Essay

Network Technology and Network Administration - Essay Example It can be proved by unusual requests and complaints network pros have gotten from end users. So, now basic need is to generate awareness among all users so as to lessen the load on IT professionals. 3. Todd Fink, senior telecommunications administrator at Premier Bankcard in Sioux Falls, S.D., once got a request from a user looking for another coffee holder for his computer. After asking he came to know that customer understood CD ROM drive as coffee holder. Looking at above complaints and stories it can be understood that how important basic knowledge of computer and internet is for every user. Users don't need an encyclopedic knowledge of how their computers work or how network is configured--but they may need a little technical enlightenment here and there. Organization may provide new users with any substantial training or indoctrination to help them understand IT policies and best computing practices, and that often translates into problems for support techs. One way to head off at least some of the problems is to educate users about certain key computing basics. This will save time and money of users and organization as well. Here are some important things that are most critical for users to know, such as how to: Computer software is a compilation of structured, written instructions that are executed by the physical components of personal system. Physical components of your PC do not understand human language, so those instructions are written by highly trained computer programmers, using languages (set of commands) that your personal computer does understand. Examples of software are windows, Linux etc Physical Parts of PC (Hardware) You use computer programs Computer programs take your commands through Keyboard or a Mouse Computer programs use the special language to communicate with CPU CPU executes what
