Name two examples of lateral gene transfer to eukaryotes that involve cellular organelles.
A) transfer of the bacterial spindle apparatus to form ribosomes and transfer RNAs
B) transfer of bacterial genes that were predecessors to mitochondria and chloroplasts
C) transfer of bacterial chloroplasts to form nuclei and ribosomes
D) transfer of the bacterial mitochondrial apparatus to form nuclei and ribosomes
E) transfer of bacterial genes to form nuclei and the mitotic spindle apparatus

Question

Quizplus · Accepted Answer

The transfer of bacterial genes that were predecessors to mitochondria and chloroplasts is one example of lateral gene transfer to eukaryotes that involve cellular organelles. This transfer likely occurred through endosymbiosis, where a bacteria was engulfed by a host cell and eventually evolved into an organelle within that cell.

Answer: None of the above choices
 None of the other choices are accurate examples of lateral gene transfer to eukaryotes that involve cellular organelles. Choice A is not an example of lateral gene transfer to eukaryotes or involving cellular organelles, as ribosomes and transfer RNAs are already present in eukaryotic cells. Choices C, D, and E are not accurate examples of lateral gene transfer either, as they suggest the transfer of entire organelles between bacteria and eukaryotes, which is not possible.
