The document outlines the process of protein synthesis which has two main parts - transcription and translation. In transcription, mRNA strands are created in the nucleus from a DNA template with the help of RNA polymerase. The mRNA then exits the nucleus through nuclear pores. In translation, which occurs in the cytoplasm, ribosomes read the mRNA to produce a protein. Transfer RNA molecules match their anticodons to mRNA codons and bring corresponding amino acids. The amino acids are linked together by peptide bonds to form a polypeptide chain, which becomes a protein when translation is complete.
