Chapter 3 Studyguide Qs Flashcards
Nuclear division
Mitosis
Type of cell that divides often
Any cell
Why is picture going through rapid cell division
Different stages being shown
Helicase
Breaks DNA apart
Polymerase
Puts new nucleotides on old ones
What part do spindle fibers attach to
Centrioles
Why must cells be small
Less efficient
More demanding
Needs more DNA
Longer to diffuse
Are the genes A and B different
No the same bc they contain the same DNA
Why is the band thicker in B then in A
B contains more DNA
Why is G2 checkpoint so important
It prepares the cell for mitosis, makes sure DNA is copied correctly
Why is the mitosis checkpoint so important
Makes sure cell is ready for nuclear division
“Down” concentration gradient
Move H-L
Passive Transport
What happens to a cell put into distilled water
It will be hypotonic bc the water has nothing to do in it (sugar, salt) so the water will move into the cell
Endocytosis
Active
Large movement of particles into the cell
Exocytosis
Large movements of particles outside the cell
