genetics was an Austrian Monk named Gregor Mendel‚ who established the basic laws of heredity from his studies with pea plants in the late 1800s. Mendel’s fundamental genetic principles may be applied to a variety of traits from many different organisms. Each genetic trait‚ such as flower color‚ is regulated by a pair of genes called alleles. These alleles are found at particular places on the chromosomes called loci. During meiosis‚ each pair of alleles splits up or segregates so that only one

Throughout the Centuries‚ there have been changes to the globe and therefore to the habitat of the humans‚ animals‚ plants and all of the infinite organisms that live in our planet. However‚ even though there have been changes‚ the living organisms also have adapted to their new environment by changing their genetic composition and acquiring new characteristics

title page picture What is the purpose for Genetically Modified Organisms? The purpose of GMOs is to make life easier for humans. GMOs are created with the well-being of humankind in focus. The many benefits that GMOs have today demonstrate this. They are used in research in medical fields‚ as well as in agriculture and pharmaceuticals. GMOs are beneficial to countries that suffer from any kind of nutritional deficiency. It is well-known that vitamins‚ proteins and fat are an important part

S and G2 take up the majority of the time. Cell division by mitosis is important during growth of eukaryotic organisms and is the way in which eukaryotes increase their cell numbers‚ either in a population of a single celled organism‚ such as Amoeba or yeast‚ or within the body of a multicellular organism. Growth may be allometric meaning that different parts of the organism grow at different rates. This can be due to mitosis occuring at different rates in different organs. Mitosis is also

Basic structure and function Explain the parts and how they work for fungi and bacteria Most fungal species are multicellular. Most fungi do not have flagella in any phase of their life cycle. They move toward food by growing toward it. The main body of most fungi is made up of fine‚ branching‚ and usually colourless threads called hyphae. Each fungus will have vast numbers

Are GMO’s are No or Go? There is much controversy over whether or not GMO’s‚ or genetically modified organisms‚ benefit us and should be allowed‚ or if they are more harmful and should be banned. Genetically modified foods are beneficial because they save money‚ have greater resistance to pests and viruses‚ and they can hold more nutrition than regular foods. One of the crops that have most widely been genetically modified is corn. Biologists can inject genes in the corn that make the corn resistant
