Video transcript

Hello everyone and welcome to today's video. So the genetic code was said to the universal for all organisms. It was found later that the genetic code has evolved. What are these? Stop code ons such as you? A A and you? A. G. Code for conciliate ID. Proto zones. So it turns out that we have certain organisms like conciliate ID pro to zones where these to stop code ons for example called for things that are different than the rest of the organisms. These are specific to the silly ated protas zones. In this case this you A and you A. G. Stop code ons are going to code for glutamine insulated protas owns. Making answer choice. C the correct answer to our question. I really hope this video helped you and I hope to see you on the next one.

Early detection and adherence to a strict dietary regimen have prevented much of the intellectual disability that used to occur in those with phenylketonuria (PKU). Affected individuals now often lead normal lives and have families. For various reasons, such individuals tend to adhere less rigorously to their diet as they get older. Predict the effect that mothers with PKU who neglect their diets might have on newborns.
