What do eukaryotic cell reproduce by?
Mitosis
What is the first stage of Mitosis?
Prophase
What is Prophase?
The first stage of mitosis, during which the cell's chromatin condenses into chromosomes
What is the second stage of mistosis?
Metaphase
What is metaphase?
It is the second stage of Mitosis in which motor proteins pull sister chromatids to the cell's
equator
What is the third stage of mitosis?
Anaphase
What is anaphase?
3rd stage of mitosis, sister chromatids r pulled apart & microtubules along w/ motor proteins
move the chromsomes 2 opsite poles of the cell
What is the fourth stage of mitosis?
Telophase
What is telophase?
last stage of mitosis, the nucleoli reappears, 2 new nuclear membrane begin 2 form, the cell
hast not divided completely
What is cytokinesis?
third main stage of the cell cycle, during which the cell's cytoplasm divides creating a new
celll
What is cell reproduction in eukarytic cells controlled by?
A combinations of proteins called cyclins
What are cyclins?
one of hte specific proteins that regulate the cell cycle
What is the cell cycle?
Process of cellular reproduction, occuring in three main stages:
Interphase(growth),mitosis(nuclear division), and cytokinesis(cytoplasm /)
What is interphase?
First stage of the cell cycle, during which the cell grows, matures, and replicates its DNA
What is Apoptosis?
Programmed Cell Death, protects cells form developing cancer, causes leaves to fall
What is cyclin-dependent kinase?
Enzyme to which cyclin binds during interphase and mistosis, triggering and controlling
activites during the cell cycle
What is Mitosis?
2nd main stage of the cell cycle when the cell replicated dna splits divides and 2 genetically
indentical dilpoid daughter cels are produce
