I need this for a biology project, I need three relevant questions about the role of DNA and chromosomes. I'm supposed to focus the questions on the areas of the cause and effect relationship between the genetic code and gene expression, mechanisms of gene regulation, and the role of DNA segments that do not code for proteins. I will then research the answers to the questions and submit it. I don't have any questions on this topic which is why I asked if any of you have three questions I can use. Thanks so much!!
