Can’t be the same in the universe?When you zoom in on the human body, and then zoom in, the problem of thinking about the terrible comes up

To better guide you to the ultimate question, we are perhaps the best place to start.You’re probably familiar with the word DNA, looking at your body in the microscopic world, zooming in and zooming in and zooming in, and you’re probably aware that pairs of spiraling strands of genes appear in your eyes.So, what is a genome?Simply put, a genome is an organism made up of all the genes plus other material.Genes are made up of DNA, which is made up of long pairs of A(adenine), T(thymine), C(cytosine) and G(guanine).There is no need to memorize the words that you have never heard before. You can just imagine them as a group of code according to the code names in the subtitles, because human beings are made up of countless cells, and this group of code is actually the program input to the cells.The cells interweave together to form tissues, and the different tissues coordinate with each other to form organs, and the organs work together to form a living organism, namely you!So you are who you are in large part because of your genome.Your cells need it to know what to do and when.It’s kind of like your brain is actually “alive” on its own, and what you think of as “yourself” is just an executor of command output.For example, if you want to eat, it’s not what you decide, it’s what the human body thinks it’s doing.I hope you’re not hungry enough to hear, “Honey, go to sleep. When you’re asleep, you’re not hungry…”It sounds funny and sad.That’s right, when you fall asleep, the body’s command stops, and we can no longer be the executor.How do you figure out the alphabet of the genome that makes up “me”?Figuring out the order of the billions of letters in a genome is the basic goal of gene sequencing.The genome is both very, very big and very, very small.Each letter in DNA — A, T, C, G — is only 8-10 atoms wide.And they’re all tangled up inside the cell into a ball, like a ball of wool.So to get all this DNA information from such a small place, scientists first have to break the long strands of DNA into many shorter ones.And then isolate each piece and sequence it individually.So, how do you measure it?It’s easier to think about it this way: when the sequences of DNA are complementary to each other, that piece of DNA will combine with other DNA: A with T, T with A, G with C, and C with G.If the sequences of two pieces of DNA complement each other, they join.But because the gene fragments are so small, we need some way to amplify those signals so that we can detect what each letter is.The most common way scientists use enzymes to make thousands more copies of the original gene, so that the original signal can be amplified thousands of times, so that we can use some technology to detect it.Yes, there’s nothing about the universe that can’t be figured out with magnification, and if you can’t figure it out, it’s not magnification enough!After copying, the next thing we need to do is read out all of this sequence information.To do this, we need to make another batch of special letters, each with a special color.These color-coded letters are mixed with enzymes and then added to the genome that we’re trying to read.At each site on the genome, a chemical reaction takes place in which a particular letter is attached to the corresponding letter to form a double strand of DNA, and each letter of the newly synthesized DNA carries a color label.Scientists take pictures of each piece of the genome, and then we can see the sequence of dots of color, and then we can read the sequence from those dots. Hundreds of millions of pieces of DNA are pieced together by a computer program, and we get the complete sequence of the entire genome.The next important step is to decode what these sequences actually mean.Because each person’s genome is different, these differences combine and add up to make people different from each other.It determines how we look, what we like, how we react, and even how likely we are to develop certain diseases and react differently to various medications.Here comes the “end of science” moment.That’s the ultimate abyss of human science, where the differences in our genomes are significant, and we’re all human, but we can never be the same, and it sounds like it’s necessary, because if we’re all the same, there’s no way to tell the difference between “I’m me” and “you’re you.”The fact that each person looks different is fundamental to our ability to recognize differences.But unfortunately, just as we know that the universe is expanding, in the macro universe we can never see the edge of the universe, in the micro world we can’t solve the mystery of DNA.We can do a thought experiment, put the world’s population and family planning first, if the earth is enough big, big to infinite space, then let the human infinite was born, born to a computer for computing the overload and exploded, each human still not weigh appearance, probabilistic, mathematics all finished, the so-called infinite, this was the case.We always say that anything is possible, but there is no such thing as the “exact same” in the universe. Not even twins, not even clones.It’s like a computer with unlimited memory and programs. No matter how many things are thrown in, it has enough space to store them and enough computing power to create things that never look the same.Those were the only answer simple science, human beings seem to be able to understand, it is precisely those who were not the only answer to explain the problem, let the human scientists were still covered with a layer of mist, after research to a certain depth, will be washed check, however, that insurmountable barriers, occasionally allow scientists to question the truth of the world.Just like quantum mechanics was created when humans couldn’t understand the double-slit interference experiment, who can explain quantum mechanics?”Physics does not exist.”
