5.2 Conjugation. Conjugation is the method by which bacteria physically connect with one another through their pilus to transfer genetic material (mainly plasmid DNA). Plasmid transfer from the donor to the recipient cell results in the recipient cell acquiring some of the genetic traits of the donor cell.

What is the purpose of conjugation?
Conjugation is the process by which one bacterium transfers genetic material to another through direct contact. During conjugation, one bacterium serves as the donor of the genetic material, and the other serves as the recipient. The donor bacterium carries a DNA sequence called the fertility factor, or F-factor.
What happens at the end of conjugation?
In conjugation, DNA is transferred from one bacterium to another. After the donor cell pulls itself close to the recipient using a structure called a pilus, DNA is transferred between cells.
What is the result of conjugation between a F+ and F cell?
Conjugation between F+ and F- cell usually results in: two F+ cells.
What is meant by conjugation reaction?
Conjugation reactions usually involve metabolite activation by a high–energy intermediate and have been classified into two general types: type I (e.g., glucuronidation and sulfonation), in which an activated conjugating agent combines with substrate to yield the conjugated product, and type II (e.g., amino acid ...
What is importance of DNA conjugate in reproduction?
3 Conjugation. Conjugation is an important process for genetic exchange between bacteria. The process needs mating of donor cell and recipient cell, and involves a cis-acting nick site (oriT) and the trans-acting functions given by a transfer protein. ... For convenient usage of the conjugation, the transfer of DNA from E.
What do you mean by conjugation?
Conjugation is the change that takes place in a verb to express tense, mood, person and so on. In English, verbs change as they are used, most notably with different people (you, I, we) and different time (now, later, before). ... Consider the verb to be and the examples of how it is conjugated into the present tense.
What type of reproduction is conjugation?
Conjugation is a form of sexual reproduction in bacteria. Two individual cells are united by a tube formed by outgrowths from one or both cells. Genetic material from one cell (designated the male) then passes through the tube to unite with genetic material in the other cell (designated female).
What does conjugation mean in pharmacology?
1. Chemical combination or linkage of chemical groups to organic molecules, often to produce a water-soluble form and allow more ready excretion. 2.
How does conjugation contribute to antibiotic resistance?
By undergoing a simple mating process called "conjugation," bacteria can transfer genetic material, including genes encoding resistance to antibiotics (found on plasmids and transposons) from one bacterium to another. Viruses are another mechanism for passing resistance traits between bacteria.
What is the result of conjugation between a HFR and F cell?
After the cross between Hfr cell and F- cell, recipient cell remains recipient. In this conjugation, chromosomal DNA is always almost transfer from donor to recipient cell together with portion of F- factor. So, frequency of recombination is high.
What are F+ and F cells?
F+ Cells = Cells containing F plasmid (F plasmid = Plasmid containing F factor) These are the bacterial cells which contains the F plasmid. They are called so, simply because they have F plasmid. We know plasmid is an extrachromosomal DNA that can replicate independently.
What is bacterial conjugation and what is the significance of plasmids with respect to conjugation?
Once the cells are in contact, the basal structure of the pilus makes a connection between the two cells known as the conjugation bridge. This connects the cytoplasm of the two cells, so the plasmid can transfer a copy of itself to the recipient cell.
How do you determine conjugation?
We can identify conjugation by finding the p-orbitals. Double bonds are always made from p-orbitals and a lone pair can be in a p-orbitals if it will conjugate the molecule. It needs 3 or more p-orbitals in a row to make it a conjugated molecule.
Why does conjugation increase stability?
The result of conjugation is that there are extra π bonding interactions between the adjacent π systems. This extra bonding results in an overall stabilisation of the system. This increased stability due to conjugation is refered to as the delocalisation energy or the resonance energy or conjugation energy.
What are conjugated verbs?
Conjugated verbs are verbs which have been changed to communicate one or more of the following: person, number, gender, tense, aspect, mood, or voice.
