Questions and Answers

What is genome editing?

  • A method of altering an organism's physical traits
  • An approach for introducing foreign DNA into organisms
  • A technique for making precise alterations to an organism’s or cell’s DNA (correct)
  • A process of creating new organisms through genetic modification

    • What are the two categories into which transgenics fall?

  • Homo-transgenic and hetero-transgenic
  • Intra-transgenic and inter-transgenic
  • Auto-transgenic and allo-transgenic (correct)
  • Self-transgenic and cross-transgenic

    • What are the advantages of gene technology in aquaculture?

  • Enhanced sensory perception, improved reproductive capabilities, and reduced aggression
  • Improved coloration, larger size, and longer lifespan
  • Accelerated growth rates, enhanced disease resistance, and increased temperature tolerance (correct)

    Study Notes

    Genome Editing

    • Genome editing is a technique used to make specific changes to the DNA of an organism.
    • Genome editing is used to introduce desired DNA into an organism, allowing for the introduction of new traits or characteristics.

    Transgenics

    • Transgenics can be categorized into two groups: Germ line and Somatic transgenics.
    • Germ line transgenics involve the introduction of desired DNA into reproductive cells, resulting in the trait being passed on to future generations.
    • Somatic transgenics involve the introduction of desired DNA into non-reproductive cells, resulting in the trait only being present in the individual organism.

    Gene Technology in Aquaculture

    • The advantages of gene technology in aquaculture include increased growth rates, improved disease resistance, and enhanced nutritional content.
    • Gene technology can also be used to improve the environmental sustainability of aquaculture practices.

    GMOs

    • The source of donor DNA used in creating GMOs (Genetically Modified Organisms) can come from a variety of sources, including other organisms, viruses, or bacteria.
