meshlike structure that helps move the chromosomes apart
process by which the cell nucleus is divided
first and longest phase of mitosis
As a cell increases in size, which increases more rapidly
the process by which a cell divides into two new daughter cells is called____ ______
each new cell can exchange more material than the original cell
when 1 cell divides in 2, what happens to the surface area to volume ratios in the new cells?
a full copy of all the DNA of the original cell
when a growing cell undergoes cell division, each new cell gets ____
the series of events that cells go through as they grow & divide is called______
the phase of mitosis during which the chromosomes line up across the center of the cell is _______
at the same time as telophase
cytokinesis usually occurs _______
S phase of the cell cycle
DNA replication takes place during the _______
the rate at which materials enter and leave through the cell membrane depends on the cell's______
2 daughter cells
the process of cell division results in______
sister chromatids are attached to each other at an area called the _____
if a cell has 12 chromosomes, how many chromosomes will each of its daughter cells have after mitosis?
at the beginning of the cell division, a chromosome consists of two____
The phase of mitosis during which chromosomes become visible and the centrioles separate from_____
the timing of the cell cycle in eukaryotic cells is believed to be controlled by a group of closely related proteins known as______
speed up or slow down cell cycle
in the cell cycle, external regulators direct cells to_______
uncontrolled cell division occurs in______
the second stage, division of the cytoplasm
each chromosomes consists of two identical "sister" ________
located near the middle of the chromatids
the series of events that cells go through as they grow divide
two tiny structures located in the cytoplasm near the nuclear envelope
the cell grows and replicates its DNA and centrioles
the cytoplasm pinches in half. Each daughter cell has an identical set of duplicate chromosomes.
the chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two nuclear envelopes will form.
the sister chromatids separate into individual chromosomes and are moved apart
the chromatin condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear envelope breaks down.
the chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere
fanlike microtubule structure that helps separate the chromosomes
