Embryonic pattern specification during development in some cases requires maternally contributed ‘determinants’, and in others is regulated by signaling between cells. For each of the following developmental events, indicate whether it is primarily maternally contributed determinants or instead local interactions between cells that is most important. In addition, name one […]

Q1. Imagine that you perform fruit fly crosses with dissimilar pairs of three X-linked traits specified by genes x, y, and z. You observe recombinant frequencies for the various gene pairs: xy= 6.9% yz= 7.6% xz= 0.7% what is the most possible gene order? Q2. Last year’s survey of squirrels […]

Case Study Part I Questions 1)What are the essential parts of a signaling pathway?2) How could activating a transcription factor cause long-term cellular changes?3) What roles does phosphorylation play in protein function?4) Why do think a signaling pathway needs to be regulated?5) Hypothesize some situations where it would be necessary […]
