One of the main features of this irregular state is that the width of the double-strand differs from the standard form(usually larger width as the new, irregular base pairings are weak) in that specific area. In other words, the portion of DNA which has the defective base-pair ...

In other solvents, you might have both groups in the neutral form the name amino acid suggests. The mechanism of peptide bond formation is complex and involves intermediates with tRNA in the cell and ...
