As ammonia is a weaker acid than carboxylic acid, the equilibrium will lie to the left (on the “zwitterion” side). Although amino acids are often shown in textbooks as the right-hand structure, they ...

Degeneracy of the Amino Acid Code Examination of the full table of codons enables one to immediately determine whether the "extra" codons are associated with redundancy or dead-end codes (Figure 3).

Consequently, they are fundamental components of our bodies and vital for physiological functions such as protein synthesis, tissue repair and nutrient absorption. Here we take a closer look at amino ...

Was it a continuous code, or were there "commas" (spare nucleotides) between codons that served as signals for the next amino acid (Table 1)? These questions were answered by way of several ...
