Determination
Differentiation
Metagenesis
Growth
A type of cell potency refers to an early embryo that has a potential to differentiate into any cell type.
Totipotent
Pluripotent
Multipotent
Unipotent
What are the ways on how to determine cell fate? Select all that apply.
cytoplasmic segregation
apoptosis
morphogenesis
induction
This term refers to the distinct "top" and "bottom" ends of an organism or structure of a cell as a result of cytoplasmic differences in gene expression.
cytoplasmic determinants
induction
polarity
promoter
The concentration of an inducer directly affects the degree to which a transcription factor is activated.
True
False
What do you call the process that results in the spatial organization of a tissue or organism?
apoptosis
homeotic mutation
positional information
pattern formation
What model refers to a concentration gradient of a diffusible morphogen that signals each cell to specify its position?
Bicoid
French flag
American flag
Hunchback
These genes encode a family of transcription factors that were expressed in different combinations along the length of an embryo and help determine cell fate within each segment.
Gap genes
Pair rule genes
Segment polarity genes
Hox genes
Stem cells are rapidly dividing, differentiated cells.
True
False
Which statement about determination is true?
Differentiation precedes determination.
All cells are determined after two cell divisions in most organisms.
A determined cell will keep its determination no matter where it is placed in an embryo.
A cell changes its appearance when it becomes determined.
