Protein synthesis :: DNA from the Beginning
DNA and Protein Synthesis - BioTopics
Nucleic acids are composed of subunits called nucleotides. Each nucleotide is composed of a sugar molecule containing five carbon atoms, a phosphate group, and a nitrogenous base. For DNA (deoxyribonucleic acid) the sugar is deoxyribose and the nitrogenous bases are Adenine, Guanine, Cytosine, and Thymine. For RNA (ribonucleic acid) the sugar is ribose and the nitrogenous bases are Adenine, Guanine, Cytosine, and Uracil.

There is a length of RNA upstream of the start codon which isn't actually used to build the protein chain. So how does the system know where to start? How does it find the right AUG codon from all the ones which are probably strung out along the RNA to code for the amino acid methionine?

Since protein is the major constituent of any cell, growth regulation is closely related to the control of ribosome synthesis. In fact, the number of ribosomes per. Protein genes suggests that ribosomal protein synthesis may be regulated in. 1980, to control for differential loading of RNA on each gel lane. Because the. Ribosomal assembly requires three or four separate ribosomal RNA rRNA molecules as well as ~50–80 ribosomal proteins r-proteins; the exact numbers.
