Question

Which of the following proteins get translated in the ER? a Nuclear Import Receptor b. Cytosolic chaperone protein c. Adaptor protein that binds to the Receptor Tyrosine Kinase (RTK) d. Receptor Tyrosine Kinase Covalent interactions form between which of the following: Circle all that apply. a. GPCR and its ligand b. Two amino acids forming a peptide c. tRNA and the amino acid it codes for d. Diacylglycerol and Protein Kinase C e. A-T base pairs in a double strand of DNA Which of the following statements are true about actin? Circle all that apply. a. F-actin is a polymer of G-actin monomers b. G-actin stands for actin-GTP c. Actin polymerization/depolymerization can occur from both the positive and negative ends of an actin filament d. Kinesins are motor proteins that walk along actin filaments

Explanation / Answer

Answer 3

Option A :- (true)G actin bound with ATP to form F actin polymer

Oprion B (false):-G actin stands for globular actin

Option C (true):-Treadmilling the filament dynamics enter a state of equilibrium where monomer disassembly from the (-) end and polymerization at the (+) end is balanced and maintained by a critical concentration of monomers in the cytosol.

Option D (true):-A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells.Kinesins move along microtubule (MT) filaments, and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are ATPases). The active movement of kinesins supports several cellular functions including mitosis, meiosis and transport of cellular cargo, such as in axonal transport.
