None of these diagrams are drawn to scale! Now two things happen. (i) DNA in the nucleus or nucleoid in prokaryotes directs the synthesis of m-RNA and provides it with necessary genetic information in the form of codons for the formation of specific proteins. This narrated animation illustrates the process of protein synthesis, starting with chromosomal DNA inside the cell's nucleus. Information from a gene is used to build a functional product in a process called gene expression. School subject: Biology (1061845) Main content: Protein synthesis (2049684) Labeling protein synthesis Genetics. 1: Translation initiation in eukaryotes. 69. The genetic code for a protein, in the form of messenger RNA (mRNA), is read by a ribosome, which then assembles the appropriate sequence of amino acids according to the code. The main role of ribosome is its ability to catalyse the formation of peptide bonds between amino acids, so that the amino acids are incorporated into proteins. Figure 1.

Ribosomes: The eukaryotic ribosome has two subunits: a 40S small subunit and a 60S large subunit. When this sequence sticks out of the ribosome, it’s recognized by a protein complex called the signal-recognition Question: BioFlix Activity: Protein Synthesis -Translation Part A - Translation Drag the correct labels onto the diagram to identify the structures and molecules involved in translation. This process takes place in the ribosomes, cellular structures responsible for protein production.
