[…] A human cloning is the developing technology. There are two types of cloning in relation to humans: therapeutic cloning and reproductive cloning (“Cloning--A Webliography”). Despite of the fact that some progressive groups decided to proceed with reproductive human cloning (creating a cloned human being), the majority of people as well as scientists who are engaged in animal cloning, do not support this idea. ("Scientists Prepare To Clone a Human: Experiment Aims to Help Infertile Couples"). Therapeutic human cloning is even a more controversial topic. This cloning suggests that embryos are cloned to create stem cells for probable treatment of illness, but there is no any plan to implant these embryos into a mother to allow them being developed. Governments of many countries try to make proper legislation about reproductive and therapeutic human cloning. Religious groups are also interested and studying these issues. […]
[…] There are several genes taking part in EPS production in R. solanacearum. Structural gene clusters consist of opsI, opsII, rgnII, and epsI (Chapman and Kao, 1998). The opsI and opsII gene clusters are essential for EPS and lipopolysaccharide syntheses since mutations in them influence the process of the production of both macromolecules. The opsI cluster includes a minimum of seven genes and some of them play the important role in synthesis of nucleotide sugar (Chapman and Kao, 1998). The rgnII cluster is mainly undescribed since it became necessary for EPS production not in plants, but only in culture (Chapman and Kao, 1998). Mutational analyses of epsI assume that it encodes proteins obliged for synthesis of the acidic component of EPS (Chapman and Kao, 1998). This component is extremely important for R. solanacearum infection of plants (Chapman and Kao, 1998). […]
