The Cell Cycle
interphase and mitosis
How many phases are included in interphase?
3
The division of the cytoplasm after telophase
cytokinesis
Spindle fibers have moved the duplicated chromosomes so that they line up at the midline of the cell
metaphase
The genetic information found in the nucleus during interphase
DNA
Most of the cell cycle is spent in ______________.
interphase
The phase of interphase where DNA is replicated
S Phase
Spindle fibers pull the chromosomes apart at the centromere and drag them to opposite poles
anaphase
Nuclei begin to reform
telophase
The goal of mitosis is to divide the _____________ of the cell.
nucleus
The cells produced in mitosis are called ____________ cells. They are _____________ to each other.
daughter; identical
During G1, what is formed and copied to prepare for cell division?
cell structures (organelles)
Spindle fibers begin to form
prophase
Chromosomes begin to decondense
Each half of a chromosome is called a ______________.
chromatid
Approximately how much of the cell cycle is spent in mitosis?
10%
The shortest phase of interphase
G2 Phase
DNA replicates to create duplicated chromosomes
interphase (S Phase)
The cell elongates
anaphase
The structure that holds together the chromatids of a chromosome
centromere
Record all of the steps of the cell cycle in order starting with interphase.
G1 Phase, S Phase, G2 Phase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
During G2, the cell makes _______________ needed for cell division.
proteins (enzymes)
Duplicated chromosomes are completely condensed during this stage
metaphase
Spindle apparatus has disassembled
telophase
The two structures involved in attaching to and pulling apart chromosomes during mitosis
centrioles and spindle fibers
