WebMay 18, 2016 · The two parts of photosynthesis—the light-dependent reactions and the Calvin cycle—have been described, as they take place in chloroplasts. However, prokaryotes, such as cyanobacteria, lack … WebChloroplasts evolved first because there was little to no oxygen available in Earth's early atmosphere for mitochondria to use as a final electron acceptor. The presence of some eukaryotes that lack mitochondria and chloroplasts reveals that it cannot be determined which organelle evolved first in eukaryotes.

WebThe mitochondriaand chloroplasts within our eukaryotic cells share the following features with prokaryotic cells: Their organelle DNA is short and circular, and the DNA sequences do not match DNA sequences found in the nucleus. WebIntrons can be removed by three mechanisms: 1) the nuclear spliceosome, 2) self-excision, or 3) maturase enzymes. MatK is the only maturase encoded in the chloroplast of plants. Maturases are prokaryotic enzymes that bind and excise a single intron. MatK interacts with seven different introns instead of the single intron of prokaryotic maturases.
