Briefly expalin the following, Transformation, Transduction, Conjugation
Answers
Answer:
Transformation is to change in form, appearance, or structure; metamorphose. to change in condition, nature, or character; convert. to change into another substance; transmute.example of a transformation is a caterpillar turning into a butterfly.
Transduction is the process by which DNA is transferred from one bacterium to another by a virus. It also refers to the process whereby foreign DNA is introduced into another cell via a viral vector.
Conjugation, in biology, sexual process in which two lower organisms of the same species, such as bacteria, protozoans, and some algae and fungi, exchange nuclear material during a temporary union (e.g., ciliated protozoans), completely transfer one organism's contents to the other organism (bacteria and some algae), ...
Transformation-
Transformation is the process by which a DNA molecule is taken up from the external environment and incorporated into the genome of the recipient cell. Allows for Recombinant DNA Technology. Involves use of plasmids.
Transduction-
Involves transfer genetic material from one bacterium to another by a bacteriophage. Acting as a vector, the virus carries its own genome plus a fragment of DNA from the bacterium it has recently infected. If the host bacterium survives the viral attack, recombination may occur.
Conjugation-
Bacterial conjugation is the temporary direct contact between two bacterial cells leading to an exchange of genetic material (DNA). This exchange is unidirectional, i.e. one bacterial cell is the donor of DNA and the other is the recipient. In this way, genes are transferred laterally amongst existing bacterial as opposed to vertical gene transfer in which genes are passed on to offspring.
