Organisms have been created by nuclear transfer cloning,in which a diploid nucleus from a somatic cell of an adult animal is injected into an enucleated egg cell to create an embryo.Among the many species thus cloned,there has been a prevalence of mitochondrial defects.Which of the following is a most likely explanation?
A)The transferred nucleus may destroy the egg mitochondria.
B)The egg cell may be heteroplastic before injection.
C)The somatic cell's mitochondria may have been transferred as well.
D)The transferred nucleus may have mutations that alter mitochondrial function.
E)The egg nucleus may have had one or more mutations that alter mitochondrial function.

Question

Quizplus · Accepted Answer

The presence of mitochondrial defects in cloned organisms suggests that the transferred nucleus may have mutations that alter mitochondrial function. This is because mitochondria have their own genome and are responsible for energy production within cells. If the transferred nucleus has mutations that affect mitochondrial function, it can lead to mitochondrial defects in the resulting organism.
