  In this experimental class, we delved into the biological concepts of gene randomness and natural selection through a series of practical activities. The experiment first involves distributing 100 red, black, and white beans of each type, and using different tools to transfer these beans into their respective cups. This process aims to simulate the random transmission of genes. Through this simple and intuitive approach, we can understand how the genetic combinations of offspring are influenced by random factors in biological genetics. In addition, the experiment also included observations of previously planted small plants. Unfortunately, these plants have all died, but their seeds have matured, providing us with a vivid example of the life cycle and biological continuity. Although plants themselves cannot survive, they still transmit life through seeds, reflecting how organisms in nature adapt to their environment in different ways to ensure the continuation of their species.

This class I learned mRNA (messenger RNA) plays a critical role in the process of translating genetic information from DNA into proteins, acting as a template that dictates the amino acid sequence of the protein product. Codons are sequences of three nucleotides on the mRNA molecule, each specifying a particular amino acid or a stop signal during the translation process. Understanding the relationship between mRNA and codons is fundamental in genetics and molecular biology, as it underlies the mechanism by which genes are expressed to produce proteins essential for cellular function and organism development. I learned this when I was in Middle School, It is not new for me, it is kind of review. By integrating hands-on activities and real-world applications, I can enhance students' understanding and engagement, applying the principles of mRNA functionality and codon translation to teach complex genetic concepts in a more accessible manner.
