cyclin
what is an example of a specialized cell?
various answers
What does letter B represent?
G1
the shortest stage of mitosis
metaphase
the cell grows and organelles replicate
G1 phase
internal regulators
what is an example of an unspecialized cell
stem cells
What does letter I represent?
mitosis
the stage of mitosis where the nucleus condenses and chromosomes become visible
prophase
the cell finishes growing and prepares for mitosis
G2 phase
regulators that respond to events outside the cell
external regulators
can develop into any type of cell in the body (including the cells that make up the extraembryonic membranes and placenta) ex. spores and zygote
totipotent
What does letter D represent?
G2
the stage of mitosis where spindle fibers start to pull chromosomes to opposite sides of the cell
anaphase
the longest part of the cell cycle
interphase
let cell cycle proceed only when certain steps have already happened
internal cell regulation
cells that are capable of developing into most, but not all, of the body’s cell types ex. embryonic stem cells and induced stem cells
pluripotent
What does Letter A represent?
interphase
the stage of mitosis where two daughter cells have not yet formed but are beginning to form
telophase
two daughter cells form
cytokinesis
wound healing and embryonic development
external cell regulation
limited potential to develop into many different types of differentiated cells
multipotent
What does letter F represent?
metaphase
