Today we'll discuss protein synthesis. Protein synthesis has two steps: transcription and translation.
Transcription is the first step of protein synthesis that takes place inside the nucleus where DNA is located.
During transcription, an enzyme called helicase breaks up the hydrogen bond in DNA so that another enzyme, RNA polymerase can make a copy of the information.
RNA polymerase will then copy the information from the DNA template into an mRNA or messenger RNA strand.
The second step is translation which takes place inside the cytoplasm. During translation mRNA attaches to a ribosome(rRNA) and a start codon is read. Then tRNA brings an amino acid and attaches to the codon with an anti-codon. This repeats causing the amino acids to form a peptide bond while the tRNA detaches.
Once a stop codon is read the process of bringing in tRNA with amino acids stops. Then the protein folds up and is a fully functioning protein. This is the process for protein synthesis. - Chris Boyd
