Question
Chapter 31, Problem 43P
Interpretation Introduction
Interpretation:
The protein in G-protein cascades should be determined, which plays a similar role like that of EF-Ts.
Concept introduction:
Protein synthesis (translation) is a process of generating new protein sequences inside the cell. This process takes place in the cytoplasm of the cell. This process is balanced by the degradation or export of cellular proteins. It is constituted of three steps namely, initiation, elongation, and termination.

Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below.
The above figures show the rate of actin polymerization in the presence of various concentration of profilin (Pfn). In the top figure, flourescence intensity is a measure of total actin that has been polymerized, and this is plotted versus time in seconds. The shade of blue of the lines in the top figure correspond to the shaded blue bars representing various concentrations of profilin in the lower figure. The lower graph shows the initial rates of polymerization of actin plotted again concentration. Which of the following is true:
Question 21 options:
profilin in a molecular motor
profilin is a promoter of actin polymerization
profilin replaced G-actin in an F-actin strand and breaks the filament
profilin is an inhibitor of actin polymerization
profilin binds to G-actin, preventing it from polymerizing
TPA protein function. Use at least two sentences to describe the function of the TPA protein.
SIGNALS AND TARGETS. Listed below are sample polypeptides/proteins with their signal molecule/peptide. Answer the questions that follow. If you are asked to give the amino acid sequence, provide the sequence using the three-letter names of the amino acids (eg. ser-ala-met).
