Question

Quizplus · Accepted Answer

The definition of a gene has evolved over time and includes all of the options listed. Originally, a gene was defined as a discrete sequence of DNA nucleotides, but it was later found that some genes code for multiple proteins, while others only code for part of a protein. Additionally, recent discoveries have shown that genes can have regulatory functions that do not involve protein synthesis. Therefore, the best choice is D, as it encompasses all of these definitions and more.
