what is the function of the ribosome
protein synthesis
what is the function of the mitochondria
production of ATP
(powerhouse of the cell)
what is the function of the Golgi apparatus
to package, modify and transport proteins
what is the function of lysosomes
digestion
what is the function of peroxisomes
detox
what is the function of the centrosome
determines how the cell will divide
what is the function of the microvilli
increase surface are for absorption
what is the purpose of the cilia
move substances over the cell membrane
what is the function of the flagella
move the cell (sperm)
what is the solute
the substances that is being dissolved (salt)
what is the solvent
substances in which the solute is being dissolved (water)
what is the solution
solute dissolved in solvent (salt solution)
Solutions can be of three types
hypotonic, hypertonic, or isotonic
what is endocytosis
bulk intake
what is phagocytosis
cell eating
what is pinocytosis
cell drinking
what is exocytosis
bulk output
Most of the life cycle of the cell is spent in what phase
interphase
the three phases of interphase are
G1, S, G2
when there is no reduction in the number of chromosomes in cell division it is called
mitosis
what are the four phases of mitosis
prophase, metaphase, anaphase and telephase
what phase of mitosis does the nuclear membrane and nucleus starts degenerating and eventually disappear
prophase
when does the chromatin become chromosomes
prophase
when do the centrioles start moving to opposite ends of the cell
prophase
when do chromosomes start moving toward the equator of the cell
prophase
when do spindles from the centrioles attach to the center of chromosome
prophase
centrioles have reached the opposite ends of the cell
metaphase
chromosomes have reached the equator of the cell and line up in a single file
metaphase
each chromosomes split into two chromatids and start moving to the end of the cell
anaphase
cytokinesis begins
anaphase
each chromatids (chromosome) now becomes a chromatin
telephase
spindle fibers disappear
telephase
nuclear membrane and nucleus reappears
telephase
centrioles reappear
telephase
cytokinesis is complete
telephase
What are exons
amino acids that specify information on the sequence
what are introns
they hold noncoding infromation
function of mRNA
carries the transcript code
function of rRNA
form function ribosomes (the sites of protein synthesis)
function of tRNA
decode mRNA message for amino acid sequence
what is transcription
DNA's information encoded in mRNA
What is translation
information carried by mRNA is decoded and used to assembly polypeptides
