The Cell Cycle
The continuity of life is based on the reproduction of cells
What is cellular division?
Mitosis is conventionally broken down into five stages
What is PMAT? (Prophase, prometaphase, metaphase, anaphase, and telophase.)
A special type of division that can produce sperm and egg cells
What is meiosis?
Each variant for a character, such as purple or white color for flowers
What is trait?
The production of offspring with combination of traits differing from either parent.
What is genetic recombination?
The life of a cell from formation to its own division
What is the cell cycle?
This structure is made up of microtubules and it controls a chromosomes movement during mitosis.
What are miotic spindle fibers?
The units of heredity and are made up of segments of DNA.
What are genes?
Plants that produce offspring of the same variety when they self-pollinate.
What is true-breeding?
A genetic map of chromosome based on recombination frequencies.
What is linkage map?
The sequential events of the cell cycle are directed by a distant “clock.”
What is cell cycle control system?
Protein complexes associated with centromeres
What are Kinetochores?
Genes are passed to the next generation via reproductive cells
What are gametes?
These organisms have two identical alleles for a character
What is homozygote?
A group of genetically identical individuals from the same parent.
The cell cycle stops until a go-ahead signal is received
What are checkpoints?
Sister chromatids separate
What is anaphase?
The fusion of chromosome pairs at the start of meiosis.
What is synapsis?
Breeding the mystery individual with a homozygous recessive individual to determine the genotype.
What is testcross?
This condition occurs when an organism has more than two complete sets of chromosomes.
What is polyploidy?
A cell spends most of its life during this phase
What is interphase?
The separation of the cytoplasm and cell membrane
What is cytokinesis?
A zipper-like structure holds the homologs together tightly.
What is synaptonemal complex?
When phenotype of heterozygote and dominant homozygote are identical.
What is complete dominance?
The removal of a chromosomal fragment.
What is deletion?
