[Today's Lisa Zate Topic] Until the birth of humans 3
3. Formation and birth of life
Cell = information system (; blueprint)… .. gene DNA (deoxyribonucleic acid) + metabolic system (; factory)
Deoxyribonucleic acid .. Consists of deoxyribose, phosphate and base, and there are four components of postponement (A-adenine, T-thymine, G-guanine, C-citonine).
The blueprints and factories had spouts everywhere in the ancient revisions, and the bubbles that came out of them became the foundation, and these two stuck together in the rough sea (= cells). And it is the birth of the first life that gave birth (made) to something that divides and proliferates by itself. So It is also said to be. that was it born as a result of the development of certain chemicals, especially carbon compounds, at some point in the Earth's past?
The factory that got the blueprints soon began to duplicate and increased the number and types, and such a battle began for 2.3 billion years.
Unicellular organisms extract DNA from other cells to make themselves stronger and weaker disappear.
It was in the sea that the historic revolution took place. Cyanobacteria were able to take in the sunlight as energy with their standard-bearers (photosynthesis), and photosynthesis produced a by-product that changed the earth. It is "oxygen". Oxygen combined with iron in the sea to produce iron oxide. When iron ran out, oxygen, which had nowhere to go, overflowed into the atmosphere and became the Earth = oxygen planet. At first, single cells were not good at flammable and dangerous oxygen, and when they were connected to each other, they began to form a large husk membrane. The DNA brought in was collected in the membrane. It is a nucleus (eukaryote) that is also present in humans today.
On the other hand, some unicellular organisms prefer oxygen, and energy is taken from oxygen to increase the momentum by 20 times. And the incident happens.
An energetic creature jumped into a creature with a nucleus. The united organism is the mitochondria that are still inside the cell. In this way, the animal cells that make up all animals and today's humans were created. And again, the chloroplasts that produce oxygen by photosynthesis were further united to form plant cells. In this way, "animal cells" and "plant cells" were born.
