The stage of mitosis pictured
What is anaphase?
100
The stage of mitosis pictured
What is metaphase?
100
The phase in which the DNA is replicated
What is S phase?
100
The number of chromosomes in a human cell.
What is 46?
100
The unrestrained, uncontrolled growth of cells
What is cancer?
200
The stage of mitosis pictured
What is prophase?
200
The stage of mitosis pictured
What is telophase?
200
The longest stage of interphase
What is G1?
200
The way in which bacteria divide, where reproduction is clonal.
What is binary fission?
200
Genes that control cell division. Both alleles of these genes must be mutated in order to have a nonfunctional gene.
What are tumor suppressor genes?
300
The 3rd phase of mitosis
What is metaphase?
300
The stage of mitosis where the golgi apparatus, endoplasmic reticulum, and nuclear envelope reform.
What is telophase?
300
The stage before DNA has been replicated in interphase
What is G1?
300
Chromatin that is not expressed and is tightly wound
What is heterochromatin?
300
Normal cellular genes that stimulate normal cell growth. Mutation in one allele is enough for loss of function of the gene, which can cause uncontrolled division.
What are protooncogenes?
400
The protein that microtubules attach to on the chromosome
What is the kinetochore?
400
The name of the structures that are pulled apart in mitosis
Sister chromatids
400
The stage in which the centrioles are replicated (in animal cells)
What is G2?
400
The protein that DNA is associated with in order to begin condensation
What are histones?
400
The gene associated with retinoblastoma if it is mutated.
What is the Rb gene?
500
The stage in mitosis where chromosomes attach to microtubules, each chromosome is oriented such that the kinetochores of sister chromatids are attached to microtubules, and chromosomes move to the equator of the cell (but aren't quite there yet)
What is prometaphase?
500
The structure in a cell where the spindle fibers reach out from
What is a centriole?
500
The protein that holds the 2 identical DNA molecules (sister chromatids) together after S phase.
What is cohesin?
500
The name of the structure resulting from nucleosomes being wrapped into higher order coils
What are solenoids?
500
A specific tumor suppressor gene that plays a key role in the G1 checkpoint and monitors the integrity of DNA. This gene is absent or damaged in many cancerous cells.
What is p53?
