Examples of clone in the following topics:

  • Reproductive Cloning

    • Reproductive cloning, possible through artificially-induced asexual reproduction, is a method used to make a clone of an entire organism.
    • Reproductive cloning is a method used to make a clone or an identical copy of an entire multicellular organism.
    • This idea forms the basis for reproductive cloning.
    • It can be used for either therapeutic cloning or reproductive cloning.
    • Dolly the sheep was the first mammal to be cloned.
  • Modern Applications of DNA

    • Reproductive cloning is a method used to make a clone or an identical copy of an entire multicellular organism.
    • In cloning both the original organism and the clone have identical DNA.
    • Cloning became an issue in scientific ethics when a sheep became the first mammal cloned from an adult cell in 1996.
    • There have been attempts at producing cloned human embryos as sources of embryonic stem cells, sometimes referred to as 'cloning for therapeutic purposes'.
    • Dolly the sheep was the first large mammal to be cloned.
  • Molecular and Cellular Cloning

    • Molecular cloning reproduces the desired regions or fragments of a genome, enabling the manipulation and study of genes.
    • In general, the word "cloning" means the creation of a perfect replica; however, in biology, the re-creation of a whole organism is referred to as "reproductive cloning."
    • Long before attempts were made to clone an entire organism, researchers learned how to reproduce desired regions or fragments of the genome, a process that is referred to as molecular cloning.
    • In cloning, the plasmid molecules can be used to provide a "folder" in which to insert a desired DNA fragment.
    • Unicellular organisms, such as bacteria and yeast, naturally produce clones of themselves when they replicate asexually by binary fission; this is known as cellular cloning.
  • Production of Vaccines, Antibiotics, and Hormones

    • Modern techniques use the genes of microorganisms cloned into vectors to mass produce the desired antigen.
    • Genes cloned from the influenza virus have been used to combat the constantly-changing strains of this virus.
    • The HGH gene was cloned from a cDNA library and inserted into E. coli cells by cloning it into a bacterial vector.
  • Genetic Engineering

    • In genetic engineering, an organism's genotype is altered using recombinant DNA, created by molecular cloning, to modify an organism's DNA.
    • Recombinant DNA technology, or DNA cloning, is the process of transferring a DNA fragment of interest from one organism to a self-replicating genetic element, such as a bacteria plasmid, which is called a vector.
    • The addition of foreign DNA in the form of recombinant DNA vectors generated by molecular cloning is the most common method of genetic engineering.
  • Types of Sexual and Asexual Reproduction

    • Asexual and sexual reproduction, two methods of reproduction among animals, produce offspring that are clones or genetically unique.
    • Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.
  • Plant Reproductive Development and Structure

    • In this respect, it is a form of cloning that has been carried out by humanity for thousands of years and by plants for hundreds of millions of years.
  • Prokaryotic Reproduction

    • The prokaryote, now enlarged, is pinched inward at its equator and the two resulting cells, which are clones, separate.
  • Genetically Modified Organisms (GMOs)

    • For this reason, the desired genes are cloned and expressed in animals, such as sheep, goats, chickens, and mice.
    • The crystal toxin genes have been cloned from Bt and introduced into plants.
  • Cell-Mediated Immunity

    • Once activated, the TC creates a large clone of cells with one specific set of cell-surface receptors, similar to the proliferation of activated B cells.
    • As with B cells, the clone includes active TC cells and inactive memory TC cells.
