Answer:
Yes; this difference from bacteria is unimportant, because the many similarities between bacteria and mitochondria provide sufficient evidence in favor of the hypothesis.
Explanation:
The passage speaks about the protein synthesising ability of bacteria and mitochondria. The bacteria are single-celled microorganism and they are prokaryotic. They lack membrane bound organelles such as mitochondria. But both mitochondria as well as the bacteria has certain similarities.
The structural similarities between the cell organelle and the organism shows favourable evidence that most proteins in present-day mitochondria are made by cytoplasmic ribosomes from mRNA transcribed from nuclear genes.
Answer: Option A
Explanation:
Cyclin binds with an enzyme to produce MPF Cyclin, and as its concentration rises, it promotes mitosis.
Therefore, cyclin binds with a factor to produce MPF enzyme, and as the enzyme's concentration decreases, it promotes mitosis; the MPF Cyclin concentration remains constant, as the rise and fall of the MPF enzyme controls the cell cycle; the MPF Cyclin concentration increases and decreases in a cycle, but does not control the cell cycle are not best described the relationship between MPF and cell cycle.
