OGM - Coggle Diagram
OGM
techniques:
2 techniques involving the direct introduction into an organism of heritable material prepared outside it, including macro-injection and microencapsulation;
3 cell fusion (including protoplast fusion) or hybridization techniques for the construction of live cells, which present new combinations of heritable genetic material, by merging two or more cells, using non-natural methods.
1 techniques for recombination of genetic material involving the formation of new combinations by the use of a vector of RNA DNA molecules or their derivatives, as well as their insertion into a host organism in which they do not appear by nature, but in which they can replicate continuously;
Techniques for plants:
1 In the first case, an agrobacterium is used, a ubiquitous and harmless microorganism for humans that possesses the ability to transfer some of its genes to plants.
2 The second method, biolystics, allows to convey microprojects of gold or tungsten, covered with dna to be transferred, inside plant cells.
Techniques for animals.
2 microin nitection in embryos of embryonic stem cells (which can be transformed before being inserted into the receiving embryo);
3 the use of unarmed retroviruses (riboNucleic Acid) capable of inserting the desired characters into the cell.
1 microinjection, which consists in the injection of genes of interest into the pronucleus of fertilized oocytes;
What is its purpose?
-
for example, the resistance of a plant to a disease or insect.
What are?
-
An organism in which a new function is introduced or modified with the introduction of foreign DNA fragments.
What is it about?
Ogm are plants, microorganisms or animals in which the part of the genetic heritage has been modified by genetic engineering techniques.
