A competent bacterial strain with genes a, b, and c is transformed by a donor bacterial fragment. Cotransformation frequencies f
mina [271]

Answer:

a) Genes b and c are farthest apart.

Explanation:

Transformation occurs when a competent bacteria cell takes up genetic material from the environment. Usually a donor cell donates its gene fragment  which is then incorporated into the chromosome or plasmid of recipient bacterial cell.

Cotransformation occurs when two genes are taken up together by the recipient. The closer the genes lie to each other, more are the chances of them being taken up together. Contransformation frequency will be higher if two genes are close to each other. Here, cotransformation frequencies between three genes are given. Amongst them, the lowest frequency is 0.0064% which is present between gene b and c. Hence, gene b and c are the farthest apart.

sergey [27]

Some proteins do indeed need assistance during the folding process. the general term used for the proteins that help other proteins fold is Chaperones.

<h3>What are Chaperones?</h3>
  • Chaperones are proteins that help big proteins or macromolecular protein complexes fold or unfold conformationally. There are different groups of molecular chaperones, all of which have the same purpose: to help big proteins fold properly during or after synthesis as well as following partial denaturation.
  • Protein translocation for proteolysis involves chaperones as well. The bulk of molecular chaperones aid in protein folding by binding to and stabilizing folding intermediates up until the polypeptide chain is entirely translated, rather than providing any steric information for protein folding.
  • Based on their target proteins and location, chaperones have different unique modes of operation.
