Answer: E) K+
Explanation:
The major cation in the intracellular fluid or cytosol is potassium (K+).
Within the interstitial fluid, the major cation is sodium(Na+) and the major anion is chloride(Cl-).
They all play an important role in maintaining homeostasis(the ability to maintain a relatively stable internal state that persists despite changes in the world outside).
The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.
Their movement organs. I think it must be answer
They both have cytoplasm, cell membranes, and DNA.
Answer:
The correct answer is option A. "They only introduce supercoiling and cannot relax a covalently closed circular DNA".
Explanation:
Type II topoisomerases are enzymes that regulate the winding an unwinding of DNA during DNA replication. Basically, these enzymes are the scissor that remove the knots and tangles formed during the replication process. Is false to affirm that type II topoisomerases only introduce supercoiling and cannot relax a covalently closed circular DNA. Bacterial type II DNA topoisomerases work with the circular DNA of bacterium by changing the linking number of circular DNA by ±2.
