Mitosis
In this phase of mitosis the sister chromatids are pulled to opposite poles.
What is anaphase
Meiosis is the process of producing these kind of cells
What are gametes
Number of chromosomes in a haploid cell
What is 23
Cancer comes from the term neoplasm which means
What is new growth
What is interphase
In this phase of mitosis the chromosomes line up at the equator of the cell
What is metaphase
In this phase of meiosis, chromosome crossover may occur typically leading to increased genetic variation
What is Prophase I
What type of life cycle has both diploid and haploid dominant periods
What is alternation of generations
Genes that control positive cell cycle regulators are known as
What are proto-oncogenes
The most important part of the G2 checkpoint is to check this
What is correct DNA replication
Mitotic spindles arise from which structure
What is centrosomes
In prophase I, sister chromosomes pair up to form these structures
What are tetrads
Fusion of gametes to form this
What is a zygote
Cancer cells suppress the ability for a cell to eliminate itself in this pathway
What is apoptosis
What is the method by which bacteria divide
What is binary fission
In this phase of mitosis sister chromatids condense and the nuclear envelope begins to disappear
What is prophase
Unpacking chromatids and forming a new nuclear envelope is characteristic of what phase
What is Telophase I(sometimes)/Telophase II
This trait is considered to be the key advantage of sexual reproduction
What is genetic diversity
After this checkpoint it is difficult to stop the cell from going through to mitosis which gives it this name
What is restriction point
When both copies of this gene are disfunctional (inherited or mutated) several cancers may arise including childhood eye cancer
What is the Rb gene
Another name for mitosis
What is Karyokinesis
The actin ring that separates the cell in cytokinesis
What is a cleavage furrow
The biological hypothesis that predators evolve with their prey and parasites with their host
What is the Red Queen Hypothesis
This protein controls many functions in the cell, and is controls the G1 checkpoint in a cell which includes identifying errors in DNA
What is p53
These two types of proteins are termed positive regulators as they drive the cell cycle
What are cyclins and cyclin dependent kinases
