In this article, foeniculum vulgare is assayed in vitro for antibacterial activity. They used 27 phytopathogenic bacterial species and 2 myropathogenic bacterial species. A significant antibacterial activity is determined by agar diffusion method and reported that foeniculum vulgare essential oil is useful for natural bacterial to control of bacterial disease of plant and seed mainly in organic agriculture. In day today life people used to smoking, poor diet maintenance…

(Scupin&DeCorse 2012). Mutations are alterations of genetic material at the cellular level. They occur spontaneously during the cell replication process, or they can be induced by environmental factors such as radiation (Scupin&DeCorse 2012). This means that the DNA sequence changes for every human which then changes the genotype and phenotype for…

Consequences of Antigen-antibody Binding:- Interaction of antigen and antibody is a bimolecular association and it never lead to an irreversible chemical modification in either the antibody or antigen. The association between antigen and antibody includes various non-covalent interactions between the antigenic determining factor (epitope) of the antigen and the…

CHAPTER 1 INTRODUCTION Since time immemorial microorganisms have played a significant role in the life of mankind owing to the production of the myriad enzymes and secondary compounds that they synthesize (Demain 1981). These micro organism live in a highly diverse environment ranging from hot springs to deep ocean sediments. In the hyper diverse environment where one can find a specialized and unique biological niche is the intracellular space between cells of higher plants acts as suite and…

We have recently published DeNovo, a prototype model for predicting virus-host protein-protein interactions (PPIs). All previous research was focused around predicting HIV-human interactions for lack of data for the other viruses. DeNovo is the first model to allow predicting the interactions between human and any virus, even if that virus has no known interactions with human. In DeNovo-II, the output of this deliverable, we developed the prototype DeNovo to a full working prediction model…

differences in DNA replication between eukaryotes and prokaryotes. Are the changes in eukaryotes adaptations? Explain. Introduction Before we start our discussion, let us refresh our memories; cells are the absolute smallest building blocks of life, each manifesting a sophisticated design. Broadly speaking, the cells are divided in eukaryotes that contain membrane-bound organelles; and prokaryotes that do not (Diffen, 2007)—in short, prokaryotes are both simpler and smaller. The DNA is the…

1. ABSTRACT: A total of 552 serum samples of sheep, goats and cattle from different localities at Assiut governorate, Egypt were screened for qualitative analysis of the BTV antibodies using a commercial competitive ELISA (cELISA) kit. The results showed an overall percentage of BTV positive sheep, goats and cattle serum samples were 41.86%, 24% and 85.42% respectively. A highest percentage of seropositivity was found in Arab El- Awamer farm(100%), followed by Abnoub( 63. 64%), Sedfa(11.…

GENE REGULATION: Gene regulation is the method of limiting the genes in the cell’s DNA, which are expressed. It is utilize to form a functional manufacture for an example protein. Various cells in a multi cellular organism might express very difficult group of genes. Although, they consist the similar DNA. Human having over ten thousands of genes in their genome. Cells are expressed the all genes. Even an organism as simple as bacterium must carefully regulate gene expression. Ensuring that the…

Introduction: Pharmacogenomics is the study of how genes affect an individual’s response to drugs. This is a new field that combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop fruitful, safe medicines and doses that will be customized to a human genetic makeup. Now drugs that are available are “one size fits all,” but they do not effective for every person. It is very tough to augur that a person get benefit from drug or not, and…

In modern molecular biology and genetics, the genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). The genome includes both the genes and the non-coding sequences of the DNA/RNA. Understanding Human Genetic Variation Genetics is the scientific study of inherited variation. Human genetics, then, is the scientific study of inherited human variation. We study genetic material due to following reasons; 1. One reason is simply an interest in better understanding…
