Medical Microbiology
Of living cells, such as reproduction, nutrition and movement; however they lack respiration, making them difficult to define as either living or non-living. Unlike bacteria or other cell, viruses contain only DNA or RNA, they do not contain both. Viruses have an unusual form of pathology. Once present in the host’s system, they invade the cells of the host, using the machinery of the cell to replicate themselves. When they have replicated sufficiently, the new viruses burst out of the host

The concept of 'personalised medicine' is hard implement. Discuss this statement
This kind of treatment approach can be referred to as reactive. This is because treatment begins upon establishment of signs and symptoms of a disease.Edgecoe (2004) reveals that the impact of personalised medicine has already been realized across the globe. Quite a number of diseases including breast cancer, HIV/AIDS and cardiovascular diseases are now being managed by the system.Another advantage of personalised medicine is that, a good understanding of environmental and genetic factors

Mating competition between males, Greater control of fertilization by one sex, and Sexually dimorphic sexual behavior between leopard snails
Therefore, it is not obvious that the males will be in competition to win females.The male mating competition in leopard slugs is very exciting. This is because the species is hermaphrodites. The organ that represents the male species looks like two daggers. They are used for both mating and hunting. The slugs involve in penis fence during mating. The partner who gets stubbed becomes the mother by absorbing sperms which later get fertilized.The mode of fertilization will determine if it is the

Mitochondria have circular DNA which replicates similar to bacteria by a reproductive process called fission, they can make their own proteins.Moreover, as the structure always relate to the function, the presence of double membrane, i. a smooth outermost membrane and an inner membrane which has many folds known as cristae. The cristae increase the surface area; thereby they enhance productivity of cellular respiration. Plant cells are known to be rigid structures with a defined shape which is

The formation of a microtubule fiber consists of a dimer bound with either GTP (straight) or GDP (curved), depending on whether the plus end undergoes shrinkage (catastrophe) or elongation (rescue) (Galjart, 2010).As shown in figure 2, the plus end of an elongating microtubule fiber contains a GTP cap which attracts dimers with GTP. The straight arrangement of the GTP-containing dimers ensures that the elongating or rescuing tubules are stable enough while expanding. On the other hand, as the

Trifolium isthmocarpum
Generally, Trifolium species are recognised as being salt-sensitive. However, research undertaken on a limited number of species (Gibberd et al., 2001) suggests that species do vary in their response and that further research, may be beneficial in identifying species, that are suited to mild or moderate saline. Trifoilum- isthmocarpum Brot (annual clover) is one of these clovers that have not been researched largely. It is grown in moderately saline areas where traditional forage legumes cannot

Describe the biochemical basis of a disease that is a result of a single gene disorder
One such gene mutation is the production of abnormal versions of beta-globin known as the HbS; other mutations in the sickle cell anemia include the HbC and HbE. The DNA sequence in sickle cell anemia carriers is the main reason why the disease is mutational. This means that those suffering from the gene mutation of sickle cell are propagated from the presence of these genes (Kawthalkar, 2012).The sickle cell anemia is an inherited and lifelong disease; patients inherit two genes for the sickle

Snail lab report on position of the snail :vetically and horizontal and how tempreture affect the snail
In land, the shell usually hampers the movement of the snail however in water its shape affords the snail a measure of buoyancy thus making it easier for the snail to move.Snails have three body parts which include the head, visceral mass and the foot. The snail lacks any bones or a spine. This enables the snail to contact and extend in such a manner that it can fully retract into its shell. The behavior of snail is mainly dependent of the environment in which it exist i. rocky, forests, damp,
