The Cell Cycle
Match the terms to the events of the cell cycle
G1 Phase
• Division of nuclear material: the nucleus divides in
two with a complete set of DNA instructions moving to
each pole of the cell
S Phase
• Cell Growth: Cell is actively performing
its function and is increasing its size
G2 Phase
• DNA Replication: Each DNA molecule is copied so that
when the cell divides each daughter cell will receive one
complete set of instructions
Mitosis
• Cytoplasmic Division: the cytoplasm and organelles
divide so that 2 functioning daughter cells are produced
Cytokenesis
• Preparation for Mitosis: The cell is approaching its
maximum size and doing final preparations for cell divisions

Terms to know:
drag the term to its definition
centromere
• the sticky region that holds two sister
chromatids together
chromosomes
sister chromatids
• two parts of a double-stranded chromosome
that have identical instructions
• structures stored in the nucleus that code
the instructions to form each new cell
diploid
gametes
• two copies of each chromosome
• reproductive cells
parent cell
• the original cell that will divide to form
two new cells
daughter cell
• a new cell produces through cell division
of a parent cell
mutations
• errors in mitosis or DNA replication
crossing over
process during which non-sister chromatids exchange
that can result in damaged cells
• genetic information
homologous chromosomes
haploid
• similar chromosomes that form pairs, one
from your mother and one from your father
• only one copy of each chromosome

Getting it straight: Sister chromatids and homologous chromosomes
Consider chromosomes as they appear, short and thick, in metaphase
