Genetic disorders can result when sister chromatids fail to separate properly.
During which phase is this problem most likely to occur?

Anaphase Il of meiosis is the phase in which sister chromatids fail to separate properly from each other. It is a genetic disorder.

This nondisjunction also occurs in mitosis of cell division. It cannot pass from parents to offspring because mitosis occurs in body cells not sex cells. This nondisjunction in mitosis causes serious disease such as cancer. Cancer disease also contain abnormal number of chromosome.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
