Interphase
This phase occurs between cell birth and cell division
Interphase
Nuclear division that forms two identical daughter nuclei
Mitosis
This nuclear division reduces the chromosome number in half and primarily occurs in sexual reproduction
Meiosis
After a haploid sperm and a haploid egg fuse a diploid _________ is formed
zygote
During this stage, DNA replication (synthesis) occurs
S Stage
The phase in which the centrosomes begin to migrate to opposite ends of the cell and the nuclear envelope begins to dissolve
Prophase
Dusing this phase crossing over may occur
Prophase 1
Oogenesis begins at what age in humans
in the fetus
During this stage, a cell doubles its organelles and prepares for DNA synthesis
G1 Stage
The phase in which the microtubules complete the spindle and the chromosomes line up on the metaphase plate
Metaphase
When homologues separate during Anaphase 1, this happens to increase genetic variation
independent assortment
Primary spermatocytes are diploid, secondary spermatocytes are ________________
haploid
During this Stage proteins are synthesized to prepare for cell division
G2 Stage
The phase in which the sister chromatids move to opposite ends of the cell
Anaphase
Daughter cells produced during telophase 2 have the ____________ number of chromosomes
Haploid
During the G1 and G2 checkpoints, if the DNA is damaged the cell is destroyed through this natural process, which is also Sydney's favourite word.
Apoptosis
The phase in which the nuclear envelope reassembles and the spindle disassembles.
Telophase
The phase between Meiosis 1 and Meiosis 2
Interkinesis
