Which of the following is falseabout dynamic instability of a microtubule end? a) during a growth phase, assembly of gtp-tubulin is faster than incorporated gtp is hydrolyzed, forming a gtp-cap. b) during a catastrophe phase, hydrolysis of incorporated gtp is faster than gtp-tubulin addition, forming a gdp-cap. c) during rescue, gtp-tubulin assembles fast enough to reestablish a gtp cap. d) each end of a microtubule can undergo dynamic instability independently. e) all answers are true.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
