Many proteins interact with DNA at physiological pH because . a. Proteins are naturally attracted to DNA regardless of the pH b. Proteins and DNA interact using mainly hydrophobic interactions c. The positively charged DNA is electrostatically attracted to negatively charged regions on proteins d. The negatively charged DNA is electrostatically attracted to positively charged regions on proteins

Option D) The negatively charged DNA is electrostatically attracted to positively charged regions on proteins

Explanation:

Proteins are composed of several amino acids with positively charged amino groups in their side chain, while DNA is composed of several nucleotides with negatively charged phosphate groups.

Thus, there is an electrostatic attraction of negatively charged DNA to positively charged regions on proteins at physiological pH.

Many proteins interact with DNA at physiological pH because the negatively charged DNA is electrostatically attracted to positively charged regions on proteins.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
