You generate a Green Fluorescent Protein (GFP) tagged form of the Band 3 protein and express it in a red blood cell. The tag is on the extracellular side of the cell. You then bleach a small spot of the cell with a laser, removing the fluorescence from that spot. You already know that once ankryin and spectrin bind, they remain in association, as do Band 3 and ankryin. When you observe the spot you had bleached after 30 minutes, what do you expect? a. no green fluorescence b. green scattered throughout c. green fluorescence restricted to the outline of a triangle d. green fluorescence within a triangular domain e. not enough information to tell

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

regents of the university of california v. bakke, 438 u.s. 265 (1978), was a landmark decision by the supreme court of the united states. it upheld affirmative action, allowing race to be one of several factors in college admission policy.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
