Paulinella chromatophora acquired its chloroplast independently from all other photosynthetic eukaryotes. Which of the following would provide the BEST evidence that this independent acquisition occurred MORE RECENTLY than in all other groups?

a) the chloroplast in Paulinella has a much smaller genome than those of other eukaryote chloroplasts
b) the chloroplast in Paulinella uses the same chemical reactions to do photosynthesis as in other eukaryote chloroplasts
c) the chloroplast in all other groups contains different genes than the mitochondria in Paulinella
d) the chloroplast in Paulinella has a much larger genome than those of other eukaryote chloroplasts

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
