Advanced Cell Biology Topic: Genome Editing Aim: To demonstrate an ability to explain scientific research to a non-specialist audience. This is a key skill for all scientists and helps clarify our thinking about what is most important about a particular piece of work. Most funding applications for research require a lay summary, and this is considered an essential part of public engagement and scientific accountability. Similarly, many jobs in science involve communication of complex data to non-specialist audiences such as the general public, shareholders, or politicians. For a wider context, see also: https://www.nature.com/articles/d41586-020-00580-w The Task: Write a lay summary of not more than 250 words explaining the research described in the technical abstract below from a controversial scientific paper about genome editing in human embryos. Use the example from class to guide you in structuring the summary. You will be introduced to the scientific concepts described in the abstract in the Genome Editing lectures on the ACB course.

Consider the tree below that was obtained by doing the Growing Tree exercise. Which traits do you expect to differ between the flowers on Peak 4 and those of the common ancestor of all populations? Select all that apply. stripes spur length petal tips spur colour anthers blade colour stigmas petal colour

In the columbine tree, what do branch lengths represent? the branch lengths arbitrary (they do not represent anything)are the branch lengths correspond to the number of mutations that have occurred the branch lengths correspond to time the branch lengths correspond to the number of seeds that established a new population

Your classmate says that when they ran their simulation,anthers were the first trait to mutate (from white to yellow).When you tell your classmate that in your tree the anthers did not mutate after 800 years, they indicate that they think you did something wrong. What would you tell your classmate?Choose the answer that best fits this situation. "You are right. All of the mutations should show up within 800 years." "Hmmm. I guess I did do something wrong. My tree should be the same as yours." "Every simulation is different, and the mutations arise at random. It is completely possible that another colour might not mutate at all."

TRUE OR FALSE: Rotating branches around nodes is the same thing as cutting them off and then putting them in different places on the tree. True False
