Polypeptides fold rapidly by a stepwise process, how does the polypeptide chain arrive at its native conformation?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. proteins appear to fold in a hierarchical manner, with small local elements of structure forming and then to yield larger elements, which coalesce with other such elements to form yet larger elements and converted into its native conformation

  2. A protein-folding pathway has been highly successful in predicting the three-dimensional structure of small proteins from their amino acid sequence atleast 156 amino acid residue that have acquired their final structure

  3. Vander waal interaction play a significant role throughout the process, as the aggregation of nonpolar amino acid side chains provides an entropic stabilization to intermediates and, eventually, to the final folded structure

  4. The native conformation of the protein folding by stepwise manner such as unfolded→transition state→molten globule→folded conformation by decreasing the free energy

#General Aptitude

In cities throughout the country, there is a new direction in local campaign coverage. Frequently in local elections, journalists are not giving voters enough information to understand the issues and evaluate the candidates. The local news media devotes too much time to scandal and not enough time to policy.

This paragraph best supports the statement that the local news media
