The Cell Cycle, Cell Cycle
Terms in this set (34)
Complete separation of the 2 new cells resulting from mitosis.
A process that takes place in the nucleus of a dividing cell, involves a series of steps, and results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus.
Period of time where a cell carries out cell processes and replicates DNA prior to cell division
Chromatin condenses into chromosomes
Chromosomes line up in the middle of the cell
Sister chromatids separate
After the chromosome separates, the cell seals off, Final Phase of Mitosis.
Each half of the chromosome
A doubled rod of condensed chromatin; contains DNA that carries genetic information
Area where the chromatids of a chromosome are attached
An ordered sequence of events in the life of a eukaryotic cell; process of growth and division.
interphase stage of cell cycle where cell grows and carries out metabolic processes
interphase stage prepares to divide by copying organelles
interphase stage of cell cycle where cell replicates DNA
stage of cell cycle where the nucleus divides
Majority of cell cycle is in this stage
Cells skip checkpoints and divide uncontrollably
first stage of mitosis, nuclear envelope disappears, chromosomes condense
second stage of mitosis, centrioles move to opposite ends of cell, spindle fibers attach to chromosomes, chromosomes line up in middle
third stage of mitosis, spindle fibers shorten pulling chromosomes apart
fourth stage of mitosis, cells begin to form cleavage furrow (animal) or cell plate (plant) and divide
final stage of the cell cycle, cells divide and move apart
DNA fist condenses and forms chromosomes
Chromosomes line up at the equator of the cell.
Sister chromatids get pulled apart
Two nuclei start to re-form, cleavage begins to form.
central part of chromosome, joining the two sister chromatids
single copy of DNA strands
organelle the sends out spindle fibers
emerge from centrioles, attach to chromosomes to pull them apart during mitosis
Purpose of mitosis
divides cells that are too large, replaces damaged/dying cells, allows for growth
a pinching of the cell membrane that begins to form in telophase
identical copies of DNA joined together at a centromere to form a duplicated chromosome
