ANAT 315 Midterm: ANAT 315 – MIDTERM#2 REVIEW (B)

These are questions from cell molecularbiology, and it requires some extensive knowledge. I havetried finding the answers myself online and in my book, so this isthe last thing I know to do. I need detailedexplanations PLEASE!!!!! Someone please help!!!! Thank You!!!!

a. activate immune system

b. inhibit cell division

c. prompt apoptosis

d. trigger DNA repair

e. all of the above

I am in an embryology course right now and we've just startedcovering cell-cell communication in development. We were talkingabout the roles of the various cadherins and their discoveries butwe got to cell signaling pathways and in reading my textbook I'mfinding myself confused by these pathways-- some of those that arementioned include Notch, Wnt, FGF, TGF-beta, RTK, Jak-Stat, SMAD,integrins, PTHrP, Hedgehog, Discoidin domain receptors 1&2, andthe unfolded protein response (UPR).

I know the RTK pathway and I know the SMAD pathway, but theothers just seem to be specific ligands that are using thesepathways -- is this correct?

Should scientists be held to some standard of integrity and honesty? Who should enforce this? Why is peer review so important? Should scientists be held responsible for creating (or discovering) technology that can be used to harm others or have unforseen side effects(chemical, nuclear warfare) ? Research: It is time to gather information about the issue of protocol for scientists. Four positions are listed to help you delegate research responsibilities.

1. As an educator, develop a list of questions to be used for class discussion. Plan to respond and engage class with controversy and thought.
