Tertiary structure also concerns a …
WebJul 4, 2024 · Secondary Structure: β-Pleated Sheet. This structure occurs when two (or more, e.g. ψ-loop) segments of a polypeptide chain overlap one another and form a row of hydrogen bonds with each other. This can happen in a parallel arrangement: Parallel and anti-parallel arrangement is the direct consequence of the directionality of the polypeptide ... WebDNA. Secondary structure is the set of interactions between bases, i.e., which parts of strands are bound to each other. In DNA double helix, the two strands of DNA are held together by hydrogen bonds.The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the …
