AP BIOLOGY UNIT 4- THE CELL CYCLE

AND HEREDITY EXAM WITH COMPLETE

ANSWERS {GRADED A+}



Why does the cell cycle happen? - ✔✔as cells increase in volume, the

surface area decreases and demand for material resources increases

which limits cell size

interphase - ✔✔has 3 phases

G1= growth

S= synthesis of DNA

G2= preparation for mitosis

mitosis - ✔✔divison of the nucleus

-has 5 phases

prophase - ✔✔chromosomes become visible, nuclear envelop dissolves,

spindle forms

metaphase - ✔✔chromosomes line up in the middle of the cell

, anaphase - ✔✔chromosomes separate and move to opposite ends of the

cell

telophase - ✔✔the chromatids or chromosomes move to opposite ends of

the cell and two nuclei are formed

cytokinesis - ✔✔division of cytoplasm and reformation of cell membrane

animal cell: pinches in (cleavage) using microfilaments

plant cell: form cell plate reforms cell wall

internal controls - ✔✔enzymes and promoting factors

external signals: growth factors provide stop and go signs at the

checkpoints

how cancer forms? - ✔✔disruptions in cell cycle control(too much

division,defective tumor supressor genes, overactive genes) which are the

result of DNA damage to proto-oncogenes (regulatory genes) which make

products like cylins and cyclin-dependent kinases

mitosis - ✔✔used for growth and repair in animals; plants use mitosis to

make gametes and for growth or repair

-begins with 1 cell, makes 2 identical cells or clones;maintains

chromosome number

meiosis - ✔✔-occurs after interphase
