A researcher is comparing the genetic sequences of chloroplasts and certain cyanobacteria. What will she likely find?
A)Chloroplast genetic sequences will always be different from those of cyanobacteria, regardless of the species of cyanobacteria.
B)Chloroplast genetic sequences will always be the same as the genetic sequences contained in cyanobacteria, regardless of the cyanobacteria species.
C)Chloroplast genetic sequences may be the same as the genetic sequences of certain cyanobacteria, depending upon the species of cyanobacteria.

Question

Quizplus · Accepted Answer

Chloroplasts are believed to have descended from cyanobacteria through the process of endosymbiosis. Therefore, the genetic sequences of chloroplasts may be similar to those of certain cyanobacteria depending on the specific species of cyanobacteria. However, it is important to note that there will still be some differences in the genetic sequences due to the evolution and adaptation of chloroplasts since they became organelles within eukaryotic cells. Option A is incorrect because there may be some overlap in genetic sequences between chloroplasts and cyanobacteria. Option B is incorrect because not all cyanobacteria will have the same genetic sequences.
