So how do you write the requirements for a master's thesis in biology? Please refer to the model essay! The following is the content of my master's thesis on biology collected for you, hoping to help you! Welcome to read the reference study!

With the exploration and development of science and technology in China, the research of biological science and technology has become the focus of human attention since the 20th century. Its development is closely related to people's lives, changing people's production activities and outlook on life. With the continuous maturity of biological science and technology, biological science is gradually applied to the fields of modern medicine, agriculture and industry, and it is also of great significance to the study of gene inheritance and biochemistry. Therefore, attaching importance to the development and application of biological science is an important subject related to life. This paper expounds the development and application of biological science from three aspects: the application of biological science, the progress of research results and the influence of biological science on society.

Key words: biological science; Science and technology; Development; Application; research progress

Biological science is a discipline that studies the law of life activities and the essence of life, and it is a favorable tool to understand nature. Since 1950s, the construction of DNA double helix structure and the major breakthrough of gene recombination have made modern biotechnology gradually mature. The development of biological science has greatly promoted the development of medicine and agriculture. Paying attention to the development of biological science has brought great influence to human production and life.

I. Research achievements and development of biological sciences

(A) the implementation of the genome project

The main purpose of gene decoding is to decipher the genetic code of genes and solve the mystery of life. At present, the production of genetic map, physical map and transcription map by researchers has been completed by relevant production units, which has great theoretical progress and practical significance and high commercial value. From June 5, 2003 to 10, Chinese scientists successfully decoded the genome of Plutella xylostella. After three years of research, the genome map of Plutella xylostella was finally obtained. Scientists pointed out that we will further cooperate and communicate with people at home and abroad, and continue to carry out functional genomics and genetics research closely related to drug resistance and feeding growth and development after the genome research of Plutella xylostella is completed, so as to provide scientific basis for effective defense and continuous control of Plutella xylostella.

(B) the implementation and application of cell totipotency technology

With the further development of human genome map, more biological models will be revealed through important animal and plant genomes. Cell totipotency technology is an advanced technology to create new varieties quickly and homozygously. After 2 1 century, important theoretical issues such as the origin of organisms, the production of primitive cells, the formation and transformation of new organisms have been greatly developed in China. Human understanding of the nature of biological life will be further improved, which will have a great impact on the theoretical and practical development of biological cell totipotency technology and play a guiding role in the cultivation of new crop varieties.

(3) Biometric technology

Biometric technology refers to the technology of identifying people according to their inherent physiological or behavioral characteristics. At present, the most widely used ones include: fingerprint recognition, palm geometry recognition, voice recognition, face recognition and so on. Biometric technology is not easy to forget, has high anti-counterfeiting performance, is not easy to be stolen, is easy to carry, and is easy to be used with computers, thus enhancing the automatic management in the use process, and has been widely used in places such as winning or losing, the army, and banks. However, due to the high technical content of biometric technology, some of them are still in the experimental stage.

Second, the application of biological science.

Biological science and technology in agriculture

Since the 20th century, in the field of biological sciences, the birth of molecular biology and the rise of modern biotechnology have become one of the greatest events in the progress of human society. From the end of 20th century to the beginning of 20th century, the breakthrough research of genomics pushed biotechnology to a stage of rapid development. The development of animal, plant and microbial technology in agriculture has greatly promoted agriculture. Moreover, with the popularization and application of transgenic technology, agriculture has developed accordingly. At the same time, the use of pest resistance and herbicides has promoted the commercialization of transgenic cotton, corn, peanuts and soybeans. Modern molecular biology and traditional animal and plant breeding have given birth to new molecular breeding.

(b) the application of biological science in medicine

The application of biological science in the development of pharmaceutical industry has reached a relatively mature stage. After the reform and opening up, biotechnology pharmacy has been highly valued, and a lot of manpower and financial resources have been invested in the development of biotechnology. Therefore, China's biotechnology pharmacy has developed rapidly and reached the international level. From July, 2065438 to July, 2003, shenzhen huada gene research institute Asian Cancer Research Organization cooperated to complete the research project of stem cell oncogene, which is another important biological research achievement after the research on the integration mechanism of hepatitis B virus. By sequencing the whole genome of 88 cancer patients, some gene mutations related to the occurrence and development of hepatocellular carcinoma were found, and two key pathways of hepatocellular carcinoma were found, which laid the foundation for the development of drugs for the treatment of hepatocellular carcinoma in the future.

Third, the impact of biological science on society.

Since 1970s, with the development of biological science, breakthroughs have been made in basic research of biological science. China's achievements in biotechnology have been recognized by the public all over the world. With the rapid development of industrialization and commercialization, biotechnology has a good development environment. By summing up the development experience in various fields of society, it is concluded that the development of biotechnology still faces many challenges. China's scientific research management departments should increase human and financial support for scientific research projects of universities or scientific research groups, encourage more young scientists and technical experts to devote themselves to biological science research, and provide them with multidisciplinary training, so that the development of multidisciplinary science can be highly integrated, thus promoting the integration of multiple fields and promoting the innovation and healthy development of biological science and technology in modern society.

Four. Concluding remarks

Biotechnology research is the source of scientific application research. With the progress of science and technology and the integration of various disciplines, biological science has gradually developed from simplification to multi-level and multi-faceted science and technology, from macro-development to micro-operability. The development of biological science has had an important impact on people's production and life, and has won more and more attention. China has made breakthroughs in biotechnology development, and the research results are all over the world. I believe that if we go on like this, we will win great achievements in biological science. Strengthen the research process of biological science and technology, promote the benign and beneficial development of modern biological science and technology, and realize the rapid and good development of science and technology in China.
