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
