Just when the ancient man was at a loss and was about to lose all his previous efforts, an occasional sexual experiment made him unexpectedly discover.

Once, the ancient man arranged for the graduate students he was in charge to observe the cell structure, but this time he made an amazing discovery.

Under the high-power microscope, the graduate student discovered an organelle that looks like an elliptical shape but is obviously larger in the individual and has completely different characteristics from the mitochondria. Let’s call this thing a "organelle", which is three times larger than that of the mitochondria!

At the beginning, the graduate student thought he had made a mistake in the multiple, but when he saw that the multiple was not wrong, and the organelles obviously had different characteristics from the mitochondria. On the ground of caution, he told the ancient man about this phenomenon.

After learning about it, the ancient man attached great importance to it. He personally took the tissue cells for homogenization, centrifugation, purification, and performed pre-photo-treatment and staining. Finally, he also observed this strange organelle. Compared with mitochondria, the two were completely different.

"What's going on?" Even the ancient man who had been struggling in this professional field for decades also started to wonder.

"This cell organelle did not exist before, or in the early stages of culture, only extremely rare cells had this type of cell organelle!" The ancient man wrote in his experimental record book. "With the increase in culture algebra, this type of cell stood out and eventually reached a point where it could be observed by the experimenter."

Because of this discovery, the ancient man had to jump back to the previous step - "cell analysis". And this time, the analysis of going back gave him another gain: it turned out that this type of cell was not simply an extra cell organelle, to be precise, it had two more organelle!

These two types of organelles are very similar in appearance, both of which are oval in shape and are almost the same in size. However, one of them looks slightly longer than the other, and they will be confused if you are not careful.

Both of these organelles have a stable double-membrane structure and contain the genetic material DNA inside. By this point, some problems have become clear. These two organelles and the genetic material they carry are the root of all problems.

With this unexpected discovery, the ancient man's research entered the fast lane, and the research once again entered the "genetic material extraction" step. And soon the corresponding DNA long chains were extracted from the two organelles respectively.

The next step is to sequence the DNA long chain to further clarify the functions of the genetic material carried in these two organelles.

Moreover, the emergence of these two organelles has also given rise to a series of questions: Why do these two organelles have them in these cells? When they are inherited, do these two organelles replicate themselves with the help of the DNA they carry, or are they completed under the action of DNA in the cell nucleus?

The ancient man vaguely guessed that these two organelles should be replicated like mitochondria and chloroplasts, under the action of their own DNA, which shows that these two organelles have quite strong independence and are not encoded by genetic material common in the nucleus! Therefore, it can explain why only a few cells have these two organelles in the early stage of culture.
