Final answer:
Gene expression through polypeptide synthesis is important for the continuity of species because it ensures the transmission of genetic information, allows for adaptation, and regulates growth and development.
Step-by-step explanation:
The importance of gene expression through polypeptide synthesis for the continuity of species is that it ensures the transmission of genetic information to offspring, allows for adaptation to changing environments, and regulates the growth and development of organisms.
Gene expression is the process of turning on a gene to produce RNA and protein, which is important for the proper functioning of cells and organisms. By controlling when and how genes are expressed, organisms can pass on their genetic information to future generations, adapt to different environments, and regulate their growth and development.
For example, in multicellular organisms, gene expression allows for the differentiation of cells into specialized types, such as muscle cells or nerve cells. This specialization is crucial for the functioning of complex organisms. Additionally, the regulation of gene expression conserves energy and resources by only producing proteins when they are needed, saving space and preventing wasteful production.
