FLOW OF GENETIC INFORMATION

52
Q

flow of genetic information Occurs in three stages:

A
  • DNA replication
  • Transcription
  • Translation
53

involves the diffusion of water down the concentration gradient through a selectively permeable membrane.

A

Osmosis

65
Q

TYPES OF OSMOTIC SOLUTIONS

A
  • HYPOTONIC SOLUTION
  • HYPERTONIC SOLUTION
  • ISOTONIC SOLUTION
66
Q

lower concentration of solutes outside cell

A

HYPOTONIC SOLUTION

67
Q

The solute concentration outside the cell is less
than the concentration inside the cell. Therefore, the water concentration outside is greater than that inside, and water flows into the cell.

A

HYPOTONIC SOLUTION

68
Q

higher concentration of solutes outside cell

A

HYPERTONIC SOLUTION

69
Q

The solute concentration outside the cell is
greater than the concentration inside the cell. Therefore, the water concentration is greater inside the cell than outside, and water flows out of the cell.

A

HYPERTONIC SOLUTION

70
Q

equal concentration of solutes

A

ISOTONIC SOLUTION

71
Q

The solute concentration outside the cell is the
same as that inside the cell. Therefore, water concentration is also the same on both sides of the cell, and the net movement of water is zero
