DNA is a sequence consisting of four bases (adenine, thymine, guanine and cytosine), which is responsible for transmitting and storing biological genetic information. The sequence of DNA encodes the genetic information of organisms, and genes contain a series of genetic instructions, which control the growth, development and function of organisms.
Although DNA itself does not directly contain the knowledge points of NMET, genetics and molecular biology have studied the structure and function of DNA, further revealing the role and genetic mechanism of genes. Biology in the college entrance examination will also involve knowledge points such as DNA structure, replication, transcription and translation.
In a word, DNA is the carrier of biological genetic information, and the knowledge points of college entrance examination refer to the scope and content of knowledge of various subjects learned in high school, which are conceptually different. However, in biology, the related knowledge points of DNA and genetic information will involve the examination scope of the college entrance examination.
