Chapter 12 DNA and RNA ANSWER KEY
... 8. Answers may vary. Having a sequence of DNA that could be edited into several different mRNA molecules makes it possible for a single gene to produce several different proteins specifically used in different tissues. This allows a cell to carry less genetic material. It also makes it possible for ...
