Anatomy Ch 3 Practice Exam Questions And
Answers
Along the length of the DNA strand, information is stored in the sequence of nitrogen
bases
A sequence of three nitrogen bases can specify the identity of a single amino acid
The process in which RNA polymerase uses the genetic information to assemble a strand of
mRNA is transcription
If the DNA triplet is TAG, the corresponding codon on the mRNA strand will be AUC
Passive or leakage channels within the cell membrane permit water and ion movement at
all times
Ions and other small water-soluble materials cross the cell membrane only by passing through
a receptor protein
All transport through the cell membrane can be classified as either active or passive
, Anatomy Ch 3 Practice Exam Questions And
Answers
The major difference between diffusion and bulk flow is that when molecules move by bulk flow
they move as a unit in one direction
The rate that solute molecules are filtered depends on their size, the force of the
hydrostatic pressure, the rate at which water passes through the membrane
The transmembrane potential is important in maintaining the integrity of a cell because it
greatly increases the cell's sensitivity to its environment
The factor(s) that interact(s) to create and maintain the transmembrane potential is (are) the
membrane permeability for sodium, membrane permeability for potassium, presence of
the Na-K exchange pump
The correct sequence of the cell cycle beginning with interphase is G0, G1, S, G2, Gm
The process of mitosis begins when the cell enters the G0 phase
