Question

13 multiple choice 1 point which of the following pieces of data does not support the endosymbiosis hypothesis? mitochondria and chloroplasts are similar in size to many prokaryotes. mitochondria and chloroplasts reproduce by fission inside the cell. mitochondria and chloroplasts have their own genomes containing circular dna. many of the genes essential for mitochondria and chloroplasts to function are encoded in the nuclear genome.

Explanation:

The endosymbiosis hypothesis suggests mitochondria and chloroplasts were once free - living prokaryotes. Similar size to prokaryotes, fission reproduction, and own circular DNA support this. However, genes essential for their function being in the nuclear genome implies they are not fully independent as the hypothesis suggests.

Answer:

Many of the genes essential for mitochondria and chloroplasts to function are encoded in the nuclear genome.
