The genes thus introduced exert their benefits by either compensating for the abnormal genes or by producing beneficial protein or by supplementing the abnormal gene (Hecht, n. p.). The first gene therapy clinical trial started in 1990 (Verma and Weitzman, n.

Human and Animal Interrelationships

The nature and scope of the relationship have, however, been differing depending on the type of animal and the benefits an animal has to humans. This relationship has been conceptualized in terms of bringing animals into the human realm. Conventionally, the relationships between humans and animals that have been regarded as domestic are very variable in respect to control of specific animals such as honey-bees, elephants, cats, horses, and cattle among others (Marchello 11).

Gametogenesis is the formation of male and female gametes or sex cells. Spermatogenesis and oogenesis are the formation of male and female gametes, respectively, by the process of mitosis and meiosis. Gametes unite in the process of fertilization. The most important consequence of meiosis is that it produces an enormous amount of genetic variation through the production of different combinations of chromosomes.

Thesis proposal about antibiotic resistance pathogens in fomities

8 pages (2008 words), Download 1
In modern time the extensive use of antibiotics in treatment of bacterial infections has led to some organisms developing resistance to some antibiotic. Antibiotic resistance can be defined as a form of drug resistance in which the targeted microorganisms can resist exposure to the same drug (Hawkey, 3) Spontaneous genetic mutation in bacteria may confer resistance to microbial drug.

Isolation and Identification Of Unknown Bacteria

Additionally, struggle for existence occurs and leads to saving of character that seems profitable to the individual. Finally, the preserved character is favored to pass to the next generation. In addition, Darwin insight on the struggle of existence was also essential in the process of evolution.

“Opportunistic” Microbial Infections

3 pages (753 words), Download 1
Opportunistic germs are bacteria and fungi that are found in the mucosae and the skin of external media. They then become virulent when the general immune resistance of the organism drops. This occurs under the influence of factors that favor the change. An example of this is some drugs, and the infections that arise from opportunistic germs have of late become more frequent.

Theories of Evolution

Eventually, these small adaptation accumulate and a new species is formed (Futuyma, 2005). Punctuated equilibrium on the other hand is a scientific theory that hypothesises that evolution occurs over time and is characterised by long durations of virtual standstill (stasis) punctuated by periods in which rapid development occur toward the formation of new forms.

The 20th century can be described as a period of greatest discoveries. One of those discoveries has been on antibiotics. These drugs have been used to control disease-causing organism. The antibiotics are typically used to contain bacteria infection in human beings and other domestic animals (Engelkirk et al., 2011).
