What is the main advantage of plasmids transferring horizontally between bacteria?

Enhanced genetic diversity

Which type of recombination involves the exchange of genetic material between homologous regions of DNA molecules?

Homologous recombination

What is the process by which two DNA molecules exchange genetic information to produce offspring DNA with a novel combination of traits from each parent DNA molecule?


Which type of recombination involves the exchange of genetic material at specific target sites in the DNA?

Site-specific recombination

What is the term used to describe the movement of genetic elements within the genome, leading to rearrangement of genetic information?


Which process is important in DNA repair, genetic recombination during meiosis, and the generation of genetic diversity?

Homologous recombination

What type of mutation occurs when the resulting base triplet codes for the same amino acid as the original triplet?

Silent mutation

Which gene transfer mechanism involves the direct transfer of genetic material between bacterial cells in physical contact?


What is the process where bacterial DNA is transferred from one cell to another by bacteriophages?


What happens when a recipient cell gains the ability to participate in future conjugation events?

It becomes F+

What kind of mutations result in a different amino acid being produced due to a change in the coding sequence?

Missense mutations

Which type of DNA transfer process involves the formation of a conjugation bridge between bacterial cells?


What is the key difference between replicative and non-replicative transposition?

Replicative transposition involves making a copy of the transposon, while non-replicative transposition involves excising the transposon from one location and inserting it into another.

Which technique in Recombinant DNA Technology is used to make identical copies of DNA fragments or entire organisms?


What is the function of restriction enzymes in Recombinant DNA Technology?

To cut DNA at specific sites for precise manipulation

Which step in Recombinant DNA Technology involves introducing the recombinant DNA into a host organism's cells?


What type of recombination involves the exchange of genetic material between DNA molecules that do not have significant sequence similarity?

Non-homologous recombination

In recombinant DNA technology, what is the function of vectors (plasmids)?

To carry foreign genes into host cells

Explore the process of horizontal gene transfer in bacteria, including the dissemination of drug resistance through plasmids. Learn about different types of recombination such as homologous recombination, site-specific recombination, transposition, and non-homologous recombination.
