The competency of bacterial cells to take up plasmids from the environment can be enhanced by treating them with calcium chloride. Which of the following statements is true regarding this process? Question 23 options: Chloride ions neutralize charges on the phospholipids and DNA. Chloride ions adhere to the cell membrane and calcium ions to the plasmid DNA, thus increasing the attractive force between them. The calcium ions change the structure of the cell membrane and, as a result, the pores are enlarged. Calcium ions neutralize charges on the phospholipids of the bacterial cell membrane and on the DNA of the plasmid. Chloride ions enter the cell through protein pores in the membrane, carrying plasmid DNA with them.
