How do the intermediate filament proteins keratin, vimentin, and neurofilaments differ from each other?
a) Their central rod domains are very different and do not all form coiled-coils. b) The dimers assemble into filaments in a completely different way. c) They are different at the head and tail domains that are exposed at the surface. d) They do not differ. All intermediate filament proteins are identical.
Homework Answers
Answer: Option(c) is correct
Explanation: Intermediate filament protein is formed by a keratine family protein which is a type of fibrous protein structure which have both N and C terminal region but the arrangement is in such a way that at both end we have N terminal region making the intermediate filament non polar structure. The basic difference between the intermediate filament is the arrangement of Head (N) and tail (C) terminal region.The length variation is the basic thing to distinguish between all the types of Intermeditae filament proteins(IFS).

please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...

QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
