A vector (with respect to diseases) is an agent that transfers a pathogen from one source to another source e.g from person to person. Mosquitoes are an example of vectors, they transmit the malaria pathogen to human.
A vector can be inanimate, however, in epidemiology, vectors are defined as living organisms.
Mitosis is a process where a single cell divides into two identical daughter cells (cell division) and its main purpose is for growth and to replace worn out cells.mistakes made during mitosis can result in changes in the dna that can potentially lead to genetical disorders. mitosis is divided into five phases: 1) interphase (2) prophase (3) metaphase (4) anaphase and (5) telophase. colchicine is an oral drug used to treat or prevent gout symptoms.it is a toxic natural product and secondary metabolite.the drug colchicine prevents the spindle's microtubules from forming or growing. if given during mitosis the chromosomes would not condense; nuclear envelope would not dissolve; chromosomes would not line up for metaphase or even if so, would not pull apart in anaphase.
