Which of the following statements is not correct regarding plasmids?a...
Explanation:
Plasmids are small, circular, double-stranded DNA molecules that are commonly found in bacteria. They are considered as extra chromosomal materials, which means they are present in addition to the bacterial chromosome. Plasmids have several important roles in bacterial genetics, including the transfer of genetic material between cells, antibiotic resistance, and the ability to produce toxins or other virulence factors.
However, one of the statements mentioned in the question is incorrect. The incorrect statement is "Mostly they cannot be transmitted from cell to cell by transformation". This statement is incorrect because plasmids can actually be transferred from cell to cell by transformation, which is a process in which a bacterium takes up DNA from its environment and incorporates it into its own genome.
Other important facts about plasmids include:
- Plasmids can replicate independently of the bacterial chromosome, which means they can increase in number within a bacterial cell.
- Plasmids can be transferred between bacteria through a process called conjugation, in which a donor bacterium transfers a copy of its plasmid to a recipient bacterium through a specialized structure called a pilus.
- Plasmids can carry genes that provide a selective advantage to bacteria, such as antibiotic resistance genes or genes that enable the bacteria to survive in a particular environment.
- Plasmids can be engineered in the laboratory and used as vectors for genetic engineering, allowing researchers to introduce new genes into bacterial cells for various applications.
In summary, plasmids are important genetic elements in bacteria that can have a variety of functions and can be transferred between cells through various mechanisms.

Which of the following statements is not correct regarding plasmids?a...
Plasmid host-to-host transfer requires direct mechanical transfer by conjugation, or changes in incipient host gene expression allowing the intentional uptake of the genetic element by transformation.
