Introduction to polypeptide chain

The messenger RNA (mRNA) transcribed from a certain segment of deoxyribonucleic acid (DNA) in the nucleus penetrates from the nuclear pore into the cytoplasm and combines with the ribosome (Ribosome). Protein synthesis takes place in the ribosome. When the protein starts to be synthesized, first the ribosome is combined with the mRNA, the ribosome is attached to one end (starting site) of the mRNA, and then moves along the mRNA from the 5 ′ 3 ′ direction (when the ribosome moves forward shortly, the other It is combined again, so an mRNA can have multiple ribosomes in a row).
