Answer:
The 4 codons that code for Alanine are :-
GCU ; GCC ; GCA ; GCG ;;
codon for Valine :-
GUU ; GUC ; GUA ; GUG
Part A. Total number of possible mutations are 36.
GCU
GCU --> GCC , GCA , GCG
GCU --> GUU , GAU , GGU
GCU --> UCU , CCU , ACU
GCC
GCC --> GCU , GCA , GCG
GCC --> GUC , GAC , GGC
GCC --> UCC , CCC , ACC
GCA
GCA --> GCU , GCC , GCG
GCA --> GUA , GAA , GGA
GCA --> UCA , CCA , ACA
GCG
GCG --> GCU , GCC , GCA
GCG --> GUG , GAG , GGG
GCG --> UCG , CCG , ACG
Part B. Silent mutations occur when the last base of the codon is substituted with other bases.
Thus, the Total number of silent mutations are 12.
Part C. Conservative mutations occur when the second base of the codon is substituted to a "U".
Thus, the Total number of conservative mutations is 4.
Motor proteins provide for molecular motion in cells by interacting with Cytoskeletal Structures, that would be the correct answer.
