The statement that best summarizes the development of knowledge about DNA over time is:
c
Scientists gained more knowledge about DNA as new evidence became available.
Scientific understanding, especially in fields such as genetics, evolves as new evidence and discoveries are made. Each new finding builds upon the previous ones, refining and expanding our comprehension of DNA. Rather than discarding past knowledge, scientists incorporate new data to develop a more complete understanding of DNA's structure and function.
