Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemica
Salsk061 [2.6K]

Answer:

Random mutations led to evolution of pesticide resistance genes in bed bugs.

Explanation:

Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.

What levels of protein structure would be affected if all hydrogen bonding interactions were prevented? check all that apply?
fgiga [73]

The proteins exhibit four levels of organization:  

1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.  

2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.  

3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.  

4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.  

Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.
