Homology

of evidence to prove that this theory is actually true. The three trustworthy evidence for this theory is fossil evidence, homologies, and biogeography. Fossil evidence are the evidence that found in the fossil of a species. Scientist determine the age based on the level of the dust that they found the fossil, and how the structure closely relative to each other. Homologies is a study about a body part, its structure and function. Different species related to each other by the structure of their…

2. Materials and Methods: The entire procedure for the identification of appropriate drug targets and prediction of inhibitor is shown in Figure 1 through schematic diagram. 2.1 Pathway analysis of the host and pathogen The Kyoto Encyclopedia of Genes and Genomes (KEGG) database [1, 2] was explored for metabolic pathways for both human genomes and Shigella flexneri 2a (301). The identification numbers of all pathways from both organisms were listed. Thereafter, a manual comparison was made…

The results show that the protein derived from the Drosophila cDNA sequence and the human protein share the same domain, also, there is a high degree of homology between the two proteins. Therefore, the Drosophila Melanogaster plasmid DNA sequence codes for a protein that has a human homologous involved in human physiology. Researchers are still investigating the function of my protein in Drosophila Melanogaster. However, the function of the homologous protein in human is pretty clear. Indeed,…

Introduction Tafazzin, encoded by the nuclear gene TAZ is primarily found in the inner mitochondrial membrane, where it plays an important role in cardiolipin (CL) remodeling (Xu et al. 2006). Tafazzin shares amino acid sequence homology to acyl transferases (Vreken et al. 2000). TAZ is located on chromosome Xq28 and comprises 11 exons and 2 alternative translation initiation sites (Johnston et al. 1997). Among four major transcripts: TAZ-FL (full-length), TAZ-Δ5 (lacking exon 5), TAZ- Δ7…

Importance of Nicotinic Acetylcholine Receptors as a Drug Target Nicotinic acetylcholine receptors are found in humans’ central nervous system and play a major role in the peripheral nervous system, including acting as a neuronal communication channel; available at the skeleton muscle and receives acetylcholine purposely released to transmission for contraction of muscles. Additionally, they are responsible for the conversion of neurotransmitter bindings into electronic depolarization. Here, the…

When we think of analogous and homologous traits, we have to draw I close distinction between them. That is the main reason it is essential to mention that homology refers to similar traits that an organism share with another. Homologous traits are a product of direct inheritance (in other words, they are acquired as a result of one common ancestor). On the other hand, analogous refers to the trait that- although originally developed to serve a different function- have evolved to carry out an…

mouse homologues of Xlrbpa, are the most homologous to the third domain of Xlrbpa (Ito et al., 1999; Patel et al., 2000; Patel and Sen, 1998; Peters et al., 2001). In this work we show that PACT can dimerize with xl3. This fact and the high degree of homology between the third domain of PACT and xl3, are a strong indication that PACT is also…

Evolution is the change in the heritable traits and genetic codes of biological populations over successive generations which can give rise to biological diversity. Generally, evolution also define as the process which modern organisms have descended from ancient ancestors and the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth. The genetic differences that are heritable will passed on to their offspring or the…

The slowest animal in the world The three-toed sloths, tree-living mammals are the slowest animals in the world, native to South and Central America.They are so slow that their name itself means laziness or sluggishness.The maximum speed of a sloth is 0.003 miles per hour. They belongs to the genus Bradypus and the family Bradypodidae. There are four living species of three-toed sloths,naming the brown-throated sloth, the maned sloth, the pale-throated sloth, and the pygmy three-toed sloth. A…

In the 1940s, antibiotics were widely introduced as a cure for common types of diseases. However, some microbes were able to resist the impacts of these drugs, in other words, the pathogen remained alive. In order to help resolve the crisis, antibiotics were found through screenings of soil microorganisms. However, soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment, the researchers developed…
