Due to gene transfer between the organelles and the nucleus
A)some organelles may only survive in the cells in which they have transfered genes.
B)organelle genomes are the same between species
C)none of the genes that have been transfered are essential for organelle functioning.
D)organelle genomes experience lower rates of mutation.

Question

Quizplus · Accepted Answer

Gene transfer between organelles and the nucleus can result in the transfer of essential genes. If an organelle cannot transfer these essential genes to a new cell, it may not be able to survive in that cell. This can result in organelle genomes varying widely between species.

Answer: D 
 Organelles that have transferred genes to the nucleus tend to have smaller genomes with lower rates of mutation, as only nonessential genes tend to remain in organelle genomes. However, organelles that have not transferred genes to the nucleus (e.g., mitochondria in mammalian cells) may have higher rates of mutation due to their relatively large genomes and the presence of reactive oxygen species.
