a cell that allows a cell free DNA to enter by passing through its cell wall and cell membrane has to be
a.competent
b.mutated
c. lysed
Answer: a.competent
Reason:
2. Transformation of this pathogen inside the human by taking naked DNA from the outside cellular tossues through the mechanism of quorum sensing associated two regulatory system.
3. This property makes the pathogen to survive by multiplication with in the host tissue

Please Help Me Label The Cell (cell wall, plasma membrane, cytoplasm, DNA, fimbriae, flagellum, ribosomes)
When the Rb protein is phosphorylated it allows the cell to progress through the__checkpoint. OG1 OM os OG2 Question 8 2 pts What is the function of cyclin-CDK complexes? They prevent DNA replication from occurring so that a cell cannot go through the cell cycle The function as growth factors which tell the cell to divide when necessary They prevent a cell from being able to enter meiosis They phosphorylate cellular targets which allows the cell to progress to the...
Cell membranes (the walled enclosure around a cell) are typically about d = 7.0 nm thick. They are partially permeable to allow charged material to pass in and out, as needed. Equal but opposite charge densities build up on the inside and outside faces of such a membrane, and these charges prevent additional charges from passing through the cell wall. We can model a cell membrane as a parallel-plate capacitor, with the membrane itself containing proteins embedded in an organic...
Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.0 x 10 7 N/C. What is the magnitude of the force on a calcium ion with charge +e? What is its acceleration? Is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? What would change the acceleration: mass of the particle? diameter of the...
Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.0 times 107 N/C. What is the magnitude of the force on a calcium ion with charge +e? Express your answer using two significant figures.

The fluids inside and outside a cell are good conductors separated by the cell wall, which is a dielectric. Thus the cell has capacitance; charge may be stored on its inner and outer surfaces (see the figure below). It is a good approximation to treat the thin charged layer as a parallel-plate capacitor. Typically the wall is 9.50 x 10-9 m thick and has a dielectric constant of 5.00. (everybody's responses to this question before were incorrect so I need...

Increase, enter, down, depolarize b. Increase, leave, down, repolarize
The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. Assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.1 10-6 C/m2. (a) What is the magnitude of the electric field within the cell membrane? N/C (b) Find the magnitude of the electric force that would be exerted on a potassium ion...
