What happens to the mutated Braf? Is this mutation a gain of function or loss of function?
Homework Answers
Ans: Braf are basically gene which helps to give direction for making a proteins that help trasmitt. Braf gene are siganal transduction protein inside the cell and this is related to the cell growth as well as cell division.
Mutated Braf gene start overgrowth of cell or you can se gain of cell, that can further leads to cancer.
