The correct answer is - during active cellular growth and after cell lysis
Explanation:
Endotoxins, also known as LPS, are part of the outer leaflet of the outer membrane of the cell wall of gram-negative bacteria. These LPS especially Lipid A LPA released into the circulation when there is a disruption of the intact bacteria or after cell lysis. These are present in cell-associated bacteria such as Gram-negative pathogens such as Escherichia coli, Salmonella, Shigella, Pseudomonas, and others.
If the plants that are produced are fertile then they must have a chromosome number hybrid of previous two species and that is 122. This is an example of tetraploidy. It is crucial that the chromosome number of the species should be even otherwise the pairing will result in a mismatch and the produced offspring will be a sterile hybrid.
