What biological knowledge has the emergence of molecular biology subverted?

The body of a bird is mostly streamlined because the sleek streamlined shape reduces the friction between the body and the air, thus reducing air resistance. The body surface is covered with feathers, which can also reduce friction, increase buoyancy, and generate lift, so the bird can fly freely. In addition, fish can move freely in the water because they can rely on the strong movement of their trunk and tail muscles.

Another interesting phenomenon is that earthworms can crawl on rough paper, but not on glass plates, because earthworms themselves rely on the contraction and elongation of their bodies to complete their movements.

Genetic engineering, DNA recombination, and genetically directed modification of human defects and diseases should be a direction. Moreover, I heard that the rich may be willing to pay a greater price to select the good genes and eliminate the defective genes in order to create more competitive, smarter children who will become "superhumans". In the future society, great advances in bioengineering will change species or destroy species, anything is possible.

The theory of evolution is a fact that has long been proven by the academic community, but there are still people who lack knowledge who read a few flawed anti-evolution chapters and say that the theory of evolution is wrong, of course, they have no malicious intentions, but they just lack biological knowledge.

Transgenic genes are generally cut through a section of genes that do not know what function they have, and what BT toxic protein genes are connected, specifically in **I don't know, there are many possibilities, after connecting, screening will begin, and if it is found that the gene is transcribed, this part will be picked out, and then continue to screen, such as growth looks normal, such as high transgenic components. That's pretty much it. It's ready to go public.

I don't know if the biosafety experiment is done or not, and I don't know if the result is good or not, just fool the relevant departments.

Molecular biology.

Product Name: molecular biology

Definition: A discipline that studies the material basis of life phenomena at the molecular level. The study of the physical and chemical properties and changes of cell components and the relationship between these properties and changes and life phenomena, such as the transmission of genetic information, the structure, replication, transcription, translation, expression regulation and physiological functions of expression products, and the transduction of cell signals.

1. Lamarck's theory of the genetics of acquired traits.

In 1809 he published the book "Philosophy of Animals", which systematically expounded his theory of evolution, commonly known as Lamarck's theory. The book proposes two laws, namely, the principle of use-in-use and obsessive inheritance, and argues that this is not only the cause of biological variation, but also the process of adaptation to the environment.

2. Darwin's theory of natural selection.

Charles Robert Darwin, an English biologist and the founder of the theory of evolution. He once sailed around the world on the ship Beagle for five years, and made extensive observations and collections of flora, fauna, and geological structures. He published "The Origin of Species" and put forward the theory of biological evolution, which destroyed all kinds of idealistic creationism and the immutability of species.

3. Straight birth.

Orthophyticism is an evolutionary theory that opposes the doctrine of natural selection. It is asserted that biological evolution has a direction, and that organisms always evolve in a given direction regardless of environmental conditions; And the dynamics that determine the direction of evolution come entirely from the latent forces within the organism, and have nothing to do with natural selection. Scholars who hold this view have different names.

4. The "mutation theory" of biological evolution

Mutation theory is a discipline that studies how continuous gradual changes in nature and human society cause mutations or leaps, and strives to describe and control these mutations or leaps with a unified mathematical model. It summarizes people's experience on qualitative change into a mathematical model, shows that qualitative change can be achieved by leap or gradual change, and gives two methods for distinguishing qualitative change.

5. Neo-Darwinism and Integrative Evolution.

Neo-Darwinism is a modified Pissonism doctrine that is popular with Darwinism. Neo-Darwinism remains Darwinian in principle. By prescribing genetic variation through the recombination and reclassification of genetic factors, as permitted by Mendelian genetics, natural selection is now the full term for differences in survival or replication rates, or more commonly used to refer to differences in the contribution of different organisms to generations of ancestors.

6. Neutral doctrine.

In 1968, Japanese geneticist Shisei Kimura (1924-1995) first proposed the neutral theory of molecular evolution, referred to as the "neutral theory" or "random drift theory of neutral mutations", based on the research data of molecular biology. In 1969, American scholars J.L. King and T.H. Jukes affirmed this theory with a large number of molecular biology data.

b Schrödinger, in his book What is Life, attempts to explain the nature of life with the theories of thermodynamics, quantum mechanics and chemistry. This book made many young physicists begin to pay attention to the problems raised in the life sciences, and guided people to use physics and chemistry to study the nature of life, making Schrödinger a pioneer of the vigorous development of molecular biology.

A, Hooke invented the light microscope and used it in cell research.

The science that studies the phenomena of life at the molecular level. By studying the structure, function, and biosynthesis of biological macromolecules (nucleic acids, proteins), we will elucidate the nature of various life phenomena. The study includes a variety of life processes.

For example, photosynthesis, molecular mechanisms of development, mechanisms of neural activity, carcinogenesis, etc. Molecular biology is the science of studying the structure and function of biological macromolecules at the molecular level, thereby elucidating the nature of life phenomena. Since the 50s of the 20th century, molecular biology has been the frontier and growth point of biology, and its main research areas include protein systems, protein-nucleic acid systems (the center is molecular genetics) and protein-lipid systems (i.e., biofilms).

The study of the structure and function of biological macromolecules, especially proteins and nucleic acids, is the basis of molecular biology. The application of modern chemistry and physics theories, techniques and methods to molecular biology has promoted the study of the structure and function of biological macromolecules, resulting in the vigorous development of molecular biology in the past 30 years. Molecular biology is closely related to biochemistry and biophysics, and the main differences between them are:

Biochemistry and biophysics are the study of biological problems at different levels, such as the molecular level, the cellular level, the global level, and even the population level, using chemical and physical methods. Molecular biology, on the other hand, focuses on the study of the universal laws of life activities at the molecular (including multimolecular systems) level. At the molecular level, molecular biology focuses on macromolecules, mainly proteins, nucleic acids, lipid systems, and some polysaccharides and their complex systems. The transformation of some small molecules in living organisms belongs to the scope of biochemistry. The main purpose of molecular biology research is to elucidate at the molecular level the basic characteristics shared by the entire biological world, that is, the nature of life phenomena; The study of physical and chemical phenomena or changes in a particular organism or a specific organ in a particular organism belongs to the category of biophysics or biochemistry.

Molecules are the most important thing in the structure of life.
