Mitosis yields ___ identical daughter cells.
2
Each duplicated chromosome has two sister ______
chromatids
Can cancer cells make their own growth factor?
Yes
Nonreproductive cells are called _______ cells
Somatic
Are the four daughter cells of meiosis haploid or diploid cells?
Haploid
everything is aligned, sister chromatids aligned at the center
Metaphase
Chromosomes are joined at the waist by ________
centromeres
Can every patient receive personalized treatment?
No
The two phases of the cell cycle are
Mitotic (M) Phase and Interphase
Do sister chromatids separate in Meiosis I or Meiosis II?
II
pulling sister chromatids to opposite poles, (each pair are the daughter chromosomes)
Anaphase
Chromosomes are attached at LENGTH by _______
Cohesions
A normal cell is converted to a cancerous cell by a process called
transformation
In which phases of interphase do cells grow?
All of them
In which phase do synapsis and crossing over occur?
Prophase 1
centrioles move away from each other, in nucleus there is NO nucleolus (dissolved), and chromosomes start condensing,
Prophase
Chromosomes are made up of packages of _____ + _________

cleavage furrow
Chromosomes (genetic material) are duplicated in this phase
Interphase (S phase)
