Question

Mitochondria are thought to be the descendants of certain alpha proteobacteria. They are, however, no longer able to lead independent lives because most genes originally present on their chromosome have moved to the nuclear genome. Which phenomenon accounts for the movement of these genes?
A) plasmolysis
B) conjugation
C) translation
D) endocytosis
E) horizontal gene transfer

Answer 1

Answer:

correct option is E) horizontal gene transfer

Explanation:

solution

we know here that phenomenon account for movement of these genes is horizontal gene transfer because we know Horizontal gene transfer are primary mechanism for spreading of antibiotic resistance in the bacteria

and  

in many mechanism some are

(1) transformation

(2) transduction

(3) Gene transfer agents  

and that Gene transfer agent is  virus and it like element encode by host that is occur in alpha proteobacteria  

and  

we know that implant of one to other plant can transfer chloroplasts , mitochondrial and entire cell nucleus contain the genome to the potential makes new species

as that we can say here correct option is E) horizontal gene transfer
