Steps for the formation of the enzyme pepsinogen

The pepsinogen is a protein. All the proteins in the body are coded by the DNA present in the genome. The DNA's 5' -3' strand or the template strand is transcribed by the process of transcription and result in the formation of the mRNA (messenger RNA). the formation of the mRNA by the help of RNA polymerase.

Then the mRNA undergoes the process of maturation. During maturation, splicing of the introns, capping and tailing takes place. The mRNA undergoes translation and forms the amino acids, with the help of tRNA molecule. The tRNA molecules brings the amino acid according to the codon present and these amino acids form a sequence, which later assemble to form a protein.

Hence, the correct sequence would be:

1.The DNA strands unwind, and RNA polymerase binds to the template strand.

2.The synthesis of mRNA begins.

3.The mRNA undergoes intron splicing and exits the nucleus.

4.The tRNA moves through mRNA with the activated amino acids attached to it.

5.The amino acids assemble to form peptide.
