The steps for the formation of the enzyme pepsinogen in the correct order is as 1, 4, 2, 3.
Pepsinogen is a chemical that is created by the cells that exist in the stomach. During digestion, pepsinogen is converted into pepsin by the acid in the stomach, and pepsin is responsible for breaking down the proteins in food. The formation steps are as;
Step 1: The DNA strands unwind, and RNA polymerase binds to the template strand.
Step 2: The synthesis of mRNA begins. The amino acids assemble to form peptide.
Step 3: The mRNA undergoes intron splicing and exits the nucleus.
Step 4: The tRNA moves through mRNA with the activated amino acids attached to it.
