Something I have learned in this 3-class lesson is about the semi-conservative replication process which the DNA replication process sometimes occurs at the same time. The process about how the semi-conservative replication works is an enzyme called helicase cuts in half the DNA's hydrogen bonds and makes a two parted DNA molecule. Then, the leading strands chemical pairs are laid out by an enzyme that is called polymerase. And after that the lagging strands are laid out with RNA primer that leaves gaps. Then lastly, the DNA lygase jumps in and fills in for the gaps.
The theory of life on earth and how it began from one cell is L.U.C.A. Life is very diverse because of all the base pairing rules which means the bases have to pair up but still have to manipulate. There are tons of different base pairs that can line up in whatever order they want. There is one way the bases pair up, and that is A with T and C with G. These bases have to pair up with each other to manipulate themselves and create more bases
In this 3-class lesson i have learned a lot so far about DNA. DNA is what makes up a person. What needs to happen to make up a person is two people need to reproduce and their DNA combines and adds to make a human. The DNA molecules inside of people hold tons of instructions about the human body. For example, when the cell needs to know how to make an ear, tongue, toe, or any kind of body part it goes into the DNA instructions to find out how to make the ear, tongue, toe, or whatever it wants. Also on a double-helix there are four bases. THe four bases to the double-helix are thymine, cytosine, guanine, and adenine. Several important properties of the DNA are the double-helix shape, instructions for the cell, and its different nitrogen bases.
What i learned from this video is every living organism is made of chains of molecules called nucleotides. Nucleotides is what makes up a human, mushroom, fly, elephant and every living thing in the world. Nucleotides are made of carbon, oxygen, hydrogen, and nitrogen. DNA is like a huge library of books that have instructions about how to make the body parts on humans. Theres all this stuff in these books to show how to stop bone growth, for hair color, for the color of your skin, and a lot of other things.
After watching the video I was mostly shocked about the fact that there are more cells in human bodies than there are stars in the Milky Way. There is something similar to an instruction book in each and every cell in your body. every time your body wants to make something the cells go back into the instruction book to see what makes a nose or what makes your ears. Each tiny piece on a DNA is called a chromosome. Your DNA is half of your mothers and half of your fathers. XY mean that you're male and XX mean that you're female. The instructions that are thrown out of the book are called introns and the instructions that are kept in the book are called exons.
Life on earth is not possible without the genetic material that is common to living organisms on this planet. Without DNA the cells couldn't and wouldn't be able to work because it wouldn't be shown how to create proteins. Since the genetic material is vital to cellular functions, there cant be cells which mean there wouldn't be life on earth without DNA. Also the idea L.U.C.A is the idea of how life started from a cell organism. If life hadn't started from one cell, life couldn't evolve, especially without genetic materials spreading. So if the genetic material did not exist, no one would be alive on earth right now.
One thing i learned in this 3-class lesson is about photosynthesis and how it works. The way it works is by the process of plants that use to take carbon-dioxide plus water and sunlight to make something like a sugar, which is called a carbohydrate. The equation of photosynthesis is 6CO2 + 6H2O + light = C6H12O6 + 6O2. There are two stages in the process of photosynthesis, those stages are the Light reaction and the Calvin cycle. The light reaction is the first stage and the second stage is the Calvin cycle.
