Question

Quizplus · Accepted Answer

A growth factor is a chemical that promotes the growth and division of cells. Nutrients are important for cell growth and survival, but they do not specifically promote cell division. Mutagens are substances that can cause changes in DNA, but they do not necessarily promote cell division. Promoters are regions of DNA that signal the start of gene transcription, but they are not necessarily chemicals from outside the cell. Telomeres are structures on the ends of chromosomes that help protect the genetic information, but they do not promote cell division.
