Question

Which of the following is the most convenient and powerful model organism used in studying programmed cell death which is one of the factors causing tumor formation?

A. Monkey

B. C. elegans

C. Budding Yeast

D. E. coli

Answer 1

Answer: The correct option is b, Caenorhabditis elegans, and it serves as the best model for studying programmed cell death or apoptosis. The reason for this organism to serve as the best model is it is transparent. the whole-cell lineage is known, the in-vivo single-cell resolution will be easy that helps in characterizing the genes important in programmed cell death.

The option a, c and d are not correct because performing experiments on monkeys will be a complicated work due to its highly complex cell organization, while budding yeast and E. coli have been considered as a model but they do not serve as the most convenient model.
