Question

How is compartmentalization achieved in eukaryotic cells? Select one: a. Primarily by membrane-bound structures O b. Primarily by endosymbiosis O c. Primarily by cellular structures surrounded by protein O d. Primarily be the cytoskeleton, which divides the cell into different domains for different functions.

Answer 1

How The Compartmenfabigofiese achived in eukaryotic cell ? P@ a primarily by membrane bound structures Esplanation > Cégzilor compartments are often defined by, membrane enclosure These membranes provides physicul barriers to biomolecules. Au enables the ceil to carry out different metabolic activity at the same time. Transport across there barriers is often controlled in order to maintain the optimal Concentration of biomolecules within & outside of each Compartment. 2) A mutation to DNA polymuxase 11/_that eliminates the 3'-to-s' eronuclease activity would prevents > 0 Removel of base mismatches. Eseplanation → During synthesis of DNA molecule, when incorrect base pair is recognized. DNA polymerase moved buckwords by one base pair of DNA. The 3-5 exonuclease activity of enzyme, allows incorrect pair of base to excised. Mismatches in DNA base - pairing can potentially result in dysfunctional proteins du could reult in concer.

So the mutation to the DNA polymerase II would prevent the function of 3'-to-5 exonudeuse, be removal of mismatched base- pairs 3 Support the How does Theory electron tranoport endosymbiosis ? of @ Both mitochondria & chloroplast has electron transport chain associated with their inner membrane to generate energy in the Same way, prokarotes have electron transport chain in their plasma membrane to generate energy. Explaination As the explains how theory support given anower already, itse does electron transpent Theory of endosymbiosis.
