DNA Turns Into Polyptide

The process by which DNA turns into polypeptides is a complicated and long. Two main steps in changing the DNA into a polypeptide are transcription and translation, with transcription coming first. The process first starts in the nucleus of the cell. The DNA begins to unfold with the help of a helicase. During the transcription phase of the change, strands of DNA begin to unwind and the complementary mRNA is made or transcribed. The way they do this is by using the common pairs of DNA triplet bases (A-T & C-G) which are transcribed into the mRNA bases (A-U & C-G). The reason the DNA has to be transcribed is because it is too big to pass through the nucleus walls. Once the DNA has been transcribed into mRNA, the mRNA moves to the cytoplasm or
endoplasmic reticulum where it can find a ribosome. Once inside the ribosome, TRNA goes to the ribosome. Then the process of translations starts. TRNA brings anti-codons which connect with the mRNA, and they also come with amino acids. Every time a new TRNA anti codon pairs up with the matching mRNA codon, the amino acids from the TRNA make a peptide bond. Once the amino acid has made the peptide bond the TRNA can disconnect and leave, the only thing that is left behind is the already connected amino acid. After a while all that is left is the strand of peptide connected amino acids. Once they are connected they become a protein or in other words a polypeptide. Once going through the process of transcription and translation, it really isn't that hard. Some might say it’s in my DNA.
