Which protein(s) is/are NOT associated with bacterial DNA compaction?

Question

Quizplus · Accepted Answer

A) SMC (Structural Maintenance of Chromosomes) proteins are indeed associated with DNA compaction in bacteria. They are involved in chromosome segregation and can also play a role in the compaction and organization of bacterial chromosomes.
B) HU is a small, nonspecific DNA-binding protein found in bacteria that is associated with DNA bending and compaction. It is involved in the structuring of the bacterial nucleoid and plays a role in various DNA transactions.
C) Type I topoisomerases are enzymes that can induce or relax supercoils in DNA. They are involved in reducing DNA supercoiling and are therefore indirectly involved in DNA compaction processes.
D) Type II topoisomerases, such as DNA gyrase in bacteria, are directly involved in DNA compaction. They introduce negative supercoils into DNA, which is a critical step in the compaction of bacterial chromosomes.
E) Condensin is a protein complex involved in chromosome compaction and segregation in eukaryotic cells. It is not typically associated with bacterial DNA compaction, as bacteria do not have condensin; instead, they have other SMC proteins that fulfill similar roles.
Therefore, the protein(s) NOT associated with bacterial DNA compaction is:
E) condensin.
