bioneethub.in Introduction Animals that have had their DNA manipulated to possess and express an extra (foreign) gene are known as transgenic animals. The genome of their animals has been changed and they can carry genes from other species. Examples of transgenic animals include rats, rabbits, pigs, sheep, cow, monkey and fish although over 95% transgenic animals … Read more
Introduction It is technique used for determining nucleotide sequences of certain areas of DNA which are unique to each individual. DNA fingerprinting can distinguish one human being from another with the exception of monozygotic twins, 99.9 percent of base sequence. The differences occur not only in genes but also in repetitive DNA DNA fingerprinting involves … Read more
Introduction:- The sex determination in honey bee is based on the number of sets of chromosomes an individual receivers. An offspring formed from the union of a sperm and an egg develops as a female (queen or worker), and an unfertilized egg develops as a male (drone) by means of parthenogenesis. This means that the … Read more
Introduction Biological evolution is defined as any genetic change in a population that is Inherited over several generations. Till now we discussed about the concept of evolution and its different evidences like fossils, homologous structures, artificial and natural selection, etc. Now we will be dealing with the theories of evolution out forward by various biologists. … Read more
Introduction Regulation of gene expression is a biological process that ensures the proper functioning and adaptability of an organism. It involves a complex relationship of mechanisms that control when and how genes are turned on or off, thereby dictating the levels of various proteins and RNAs within a cell. This regulation is essential for maintaining … Read more
Introduction What are methods of birth control? Birth control, also known as contraception, encompasses a variety of methods and devices used to prevent pregnancy. These methods vary in terms of mechanism, effectiveness, convenience, and potential side effects. Here is an overview of the most common methods of birth control 1. Hormonal Methods a. Birth Control … Read more
characteristics of genetic code Universality One of the most striking features of the genetic code is its universality. Almost all living organisms use the same genetic code, from the simplest bacteria to complex multicellular organisms like humans. This universality suggests that the genetic code was established early in the history of life and has been … Read more
Introduction Respiration is a vital physiological process that ensures the delivery of oxygen to tissues and the removal of carbon dioxide from the body. The regulation of respiration is a complex and finely tuned process that involves multiple systems, including the central nervous system, chemoreceptors, and mechanoreceptors. This intricate regulation ensures that the respiratory rate … Read more
Introduction Inheritance of one gene Inheritance is a fundamental principle of genetics that explains how traits are passed from parents to offspring. In this context, we’ll explore the inheritance of a single gene, providing an understanding of its mechanisms, implications, and examples Understanding Gene Inheritance Basic Genetics A gene is a unit of heredity made … Read more
Introduction Parturition, commonly known as childbirth, is a complex and remarkable process marking the culmination of pregnancy, where the foetus is expelled from the mother’s uterus into the external world. It is a critical event in the reproductive cycle of mammals, including humans, and involves a series of coordinated physiological, hormonal, and anatomical changes. This … Read more
