Each spiraling strand is comprised of a sugar phosphate backbone and attached bases connected to a complimentary strand. The complimentary strand is connected by non-covalent hydrogen bonding between paired bases. The bases are adenine, thymine, ctyosine, and gaunine. The fundamental building block of DNA is the nucleotide. The nucleotide has three parts. A nitrogen-containing pyrimidine…

Hormones are organic substances that are secreted by plants and animals and that function in the regulation of physiological activities and in maintaining homeostasis. They carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they…

Human epidermal growth factor receptor 2 (HER2) is a proto-oncogene which codes for a transmembrane glycoprotein (p185), this means it is a gene which has the potential to cause cancer, and it is a tyrosine kinase on the membrane. In roughly 25% of breast cancers it is active and overexpressed, it allows the cells to…

The plant rhododendron belongs to the family Ericaceae which also includes the Heath, and there are about eight-hundred fifty species which grow worldwide (Turner and Szczawinski, 171-2). The Heath family is a large one with so many species, all of the poisonous species fall into two of its subfamilies, one of which is the rhododendron….

Carica papaya (papaya), belongs to family of Caricaceae, is a perennial plant originating from the southern part of Mexico. Carica papaya leaf juice has been used to treat various diseases, including infectious diseases and cancer. However, its anticancer and associated molecular mechanism of CPE extract remains unclear. The aim of the present study is to…

Food applications Encapsulation technology had been exploited as an alternative to protect antimicrobials, potentially enhancing their efficacy and stability in foods (Mozafari et al. 2008). Current research focused on bacteriocin food biotechnologies delivered the antimicrobials via continuous or sustained release (Chi-Zhang et al. 2004). Controlled delivery improves the efficacy of bacteriocins by ensuring the peptides…

The order Odonata is divided into three suborders: The Zygoptera, or damselflies, which can fold their wings over their abdomen, the Anisoptera or Dragonflies which can’t, and thus hold their wings straight out from their thorax, and the Anisozygoptera, an ancient suborder possible once containing the seeds of both the other 2 more modern suborders…

The unifying characteristics of all living things. Sexual reproduction produces offspring that are genetically different from their parents. Asexual reproduction produces offspring genetically identical to their parent. Asexual Reproduction Fission, budding, fragmentation, and the formation of rhizomes and stolons are some of the mechanisms that allow organisms to reproduce asexually. The hydra produces buds; starfish…

Prokaryotes have three principal structures which are posts, cocci and winding. The bacterial cell divider is irrefutably the most essential supporter of cell shape. Alive and well of cell divider, closeness or nonappearance of flagellum, and if appear, spots of flagellum, the eubacteria can be requested by Gram Stain. Above all, gram positive tiny creatures…
