Plant proteases with excellent catalytical properties perform many functions in biological systems. Vallaris solanacea, a new plant protease has been identified and screened effectively for its caseinolytic activity. This protein activity was specifically inhibited by p-chloromercuribenzoate, which showed that it is a cysteine protease. Preliminary investigations such as effect of pH and temperature on the caseinolytic activity of crude protease were done. Stability towards temperature and pH…

Regeneration is the process of renewal or restoration of a body, part of the body or biological system after a wound or as a normal process. It is the process that makes the genomes, cells and organisms flexible to natural changes that cause disturbances or damage. All species are able to regenerate from bacteria to humans. Regeneration can be of two types: it can be complete when the new tissue is equal to the lost or incomplete tissue when the necrotic tissue presents fibrosis. Different…

KRAS: So far three human Ras genes have been identified. Actually Ras homolog to the oncogene from Kristen Ras Sarcoma (KRAS). HRas homologous to the oncogene from Harvey Rat Sarcoma virus(HRAS) and NRas first isolated from the human neuroblastoma. These three different Ras genes are highly homologous but functionally different. However the degree of redundancy remains topic of investigation (Pylayeva-Gupta et al. 2011). Ras are central mediators of downstream of growth factor receptor…

1.2 Cellular DNA Damage responses, genomic instability. DNA is the blue print of life and all the information of life processes such as growth, metabolism, reproduction etc are encoded in the sequence of it. Therefore its very important to maintain the genomic integrity of this genetic material, not only to keep away defects in life processes but to pass a faithful information to the next progeny. Integrity of the DNA is usually challenged by both endogenous and exogenous agents who are capable…

Because science and technology have progressed tremendously over the past few decades, many people have wondered whether cloning humans can be possible. Human cloning is creating an identical copy of a human. There is a possibility that humans can be cloned through therapeutic and reproductive cloning. Therapeutic cloning is used for research purposes whereas reproductive cloning is used for creating an organism. In recent discussions of cloning, a controversial issue has been made on whether…

a) Human reproductive cloning / Reproduction One of two reasons for human cloning is reproduction. It`s prime objective is to produce children for couples who are unable to conceive. There are 2 ways in which this is possible. The first is a transfer of an adult nucleus into ovum. This results in an identical person yet; the mitochondrial DNA differs. The second method is by splitting the embryo, similar to the natural process that occurs in twins. This process also results in an identical…

Genetic modification is the elimination of a certain gene containing undesirable trait and adding another gene containing the desired trait. The process includes getting the desirable material from a donor and not from the parents. Parents now can get all the characteristics they desire in their babies. They can also eliminate certain health problems the child might inherit from his/her parents. Genetic modification and manipulation has become a controversial topic since it has ethical and…

Life with technology. Almost 99.9% in the daily life technology took place, wherever we turn right or left it all been changed to current technology. The technology can’t be stop because it’s one kind of virus which is created by the humans. This upgraded make influence in the education line, where most of the schools around the world changed their education structure into the current technology. According to the chart of apple selling department, in the first month of the apple I-pads released,…

Discussion The aim of this study is to determine how plant growth is affected by Rhizobia bacteria and fertilizer. The histogram in figure 1 indicates that the change in biomass of pea plant species was higher under Rhizobia + fertilizer. Pea plant species comes from a legume family. According to Taiz and Zeiger (2010), these plant species enter into a symbiotic relationship with root-nodule bacteria, referred to as Rhizobia. Based on the results, the increase in biomass under rhizobia+…

Lipids are fatty acids and their derivatives, and substances related biosynthetically or functionally to these compounds. Lipids are diverse group of organic compounds including fats, oils, hormones, and certain components of membranes that are grouped together and mainly amphipathic. The variation in head groups and aliphatic chains allows the presence of more than 1000 different lipid species in any eukaryotic cell. Different types of lipid include Phospholipids, Sphingolipids and Cholesterol…
