Homology

The term Homo stasis comes from two Greek words, Homo which means “ the same” and stasis which means “ steady ” and the literal translation is staying the same. Some refers to this term as a tendency to maintain a stable constant environment where the body continues to function properly and to maintain this state of stability the body has to resist any internal changes.however,Cannon (1932), who introduced the term ‘homeostasis’, defined homoeostasis as ‘a condition, which may vary, but remains relatively constant’.in 18870 Claude Benread stressed the necessity of the body’s ability to maintain a stable environment so that vital processes could proceed optimally and independently of environmental fluctuation, in which he proposed the idea…

Organisms that share very similar DNA sequences are more closely related than organisms with different DNA sequences. Molecular homology tends to provide more accurate relationships about similarities between organisms. Molecular biologists develop mathematical tools and use computer software to determine molecular similarities between species. By evaluating molecular homologies, biologists have discovered that humans share a very distant common ancestor with bacteria even though we have…

The first and quite possibly the best evidence for evolution is Homology. Homology is when species share similarities that are signs of common ancestry such as homologous structures. Homologous structures are ones that derive from a common ancestral structure (“Evidence of Evolution…”). These can prove to be very solid reasoning when arguing for evolution and against creationism. They have led scientists to believe that current animals have evolved from one common ancestor. An easy way to…

good. A special category of meanings that objects may hold is one of social meanings, meant to represent and differentiate social categories such as gender, class, and ethnicity. Thus, the study conducted by Tamar Liebes and Elihu Katz (1990) on TV-shows consumers proved that the viewers found different meanings for the scenes, depending on the social class and ethnicity. Between theoretical perspectives in which researchers have included studies on ways of dividing types of cultural consumption…

improvement of intelligent methodologies have resulted in the expansion of computational techniques. The computational methods for protein structure prediction can be generally classified into three approaches: homology, threading, and ab initio methods [2]. Homology modeling, also known as comparative modeling of protein, refers to constructing an atomic-resolution model of the "target" protein from its amino acid sequence and an experimental three-dimensional structure within the Protein…

The full name of EHBP1 is "EH domain binding protein 1." The symbol for the gene is EHBP1. Other names for the EHBP1 gene are HPC12, NASCIN, and KIAA0903. EH Domain Binding Protein 1 is a protein coding gene. This gene codes for an Eps15 homology domain binding protein. Its protein type is a vesicle. The encoded protein may play a role in endocytic trafficking. It is associated with prostate cancer. This gene is commonly found within the cytosol and the plasma membrane of a cell. It's size is…

2000), adipsin (White et al., 1992), leptin (Friedman, 2000), plasminogen activator inhibitor-1 (Shimomura et al., 1996), resistin (Steppan et al., 2001), and TNF-α (Hotamisligil, 1999). These hormones are part of the adipokine family which are cytokines secreted by adipose tissue. Cytokines are small signaling molecules that help regulate the behavior of other cells, including “self” or their own selves. Other cytokines include interferons, interleukins and tumor necrosis factors as well.…

Unlike the microtubule-binding region that is common to cytoplasmic and axonemal dyneins in flagella and cilia, the organelle-binding segment contains a region specific for cytoplasmic dynein heavy chain. The cDNA clone was made with the Molony leukemia virus reverse transcriptase and the mRNA was obtained from melanocyte. A cDNA clone does not contain introns in its sequence. The purpose of the 'PCR' part of the RT-PCR procedure was to confirm that human melanocytes express cytoplasmic heavy…

through evolutionary descent. All living things are fundamentally alike due to the similarities between cells at the molecular and cellular level. It is because of these similarities that indicate why species evolve from a common ancestor in the evolutionary theory. As a result this concept became known as molecular homology. Not only are organisms made of cells that contain similar structures such as the nuclei (animal versus plant), but many species share genetic similarities as well that…

The subunits are ‘chosen’ and assembled from a pool of 19 subunits (α1-6, β1-3, γ1-3, δ, ε, π, and ρ1-3), hence giving the possibility of a diverse isoform heterogeneity. In each subunit family, the members share about 70- 80% sequence homology whereas members from different subunit family share about 30- 40% sequence homology. The mature subunits are made up of approximately 450 amino acids residues and are identical in terms of topological organization. In each subunit, about half of it…
