As previously mentioned, polynucleotide phosphorylase joins nucleotides randomly ... RNAs produced proteins containing only six amino acids: asparagine, glutamine, histidine, lysine, proline ...

Proteins are chains of amino acids that are strung together according ... DNA is a chain of four molecules called nucleotides – adenine, cytosine, guanine and thymine, represented by the letter ...

For a cell to produce any given protein, it must translate a strand of RNA into a string of amino acids. Every three nucleotides of RNA, called a codon, correspond to one amino acid. But many ...

In cells today, amino acids are generated from precursors called ... a byproduct of the same reaction is orotate, a precursor to nucleotides that make up DNA and RNA. This suggests that the ...
