MrMuchimi

Answer:

The correct answer is C. catalyze the removal of phosphate residues from proteins

Explanation:

The function of protein kinase is to transfer a phosphate group to the amino-acid present in a protein and the function of protein phosphatase is to catalyze the removal of the attached phosphate group from amino acid of a protein.

Protein dephosphorylation is an important event in the post-translational modification process. Through dephosphorylation, phosphatases change the protein behavior by activating and deactivating the proteins.

Phosphorylation and dephosphorylation of proteins are important in managing several crucial processes in the cell like cell signaling, apoptosis, cell cycle, etc. So the right answer is C.

What best explains the interaction between tRNA and mRNA during translation?
Deffense [45]

In short, mRNA tells the ribosomes what amino acids to use and in what order. tRNA “retrieves” those and bring later them to the ribosomes.
