Cell growth limits/Cancer cells
100
Part of interphase where the cells are doing their specialized jobs and most cell growth occurs
What is G1 phase
100
the phase of mitosis where the shape of DNA is condensed from chromatin to chromosomes
What is prophase
100
"legs" and "arms" of chromosomes
What are chromatids
100
Process by which cell divides into two daughter cells
What is cell division
100
Limit to cell growth when cells get too big and cannot get enough materials to center of the cell.
What is exchange of materials/surface area to volume ratio
200
This is the part of interphase where DNA is replicated
What is S phase
200
the reverse of prophase
What is telophase
200
part of the chromosome that holds the chromatids in place. (belly button)
What is the centromere
200
series of events that cells go through as they grow and divide
What is the cell cycle
200
Limit to cell growth that is due to inability of organelles to access DNA efficiently
What is DNA overload
300
Phase of cell growth when the cell is not dividing?
What is interphase
300
when chromosomes line up in the center of the nucleus
What is metaphase
300
Shape of DNA during mitosis
What is a chromosome
300
disorder in which some of the body's own cells lose the ability to control growth
What is cancer
300
When cancer cells divide uncontrollably this is formed
What is a tumor
400
Cytoplasm/Cell membrane splits
What is cytokinesis
400
chromosomes pulled to opposite ends of nucleus
What is anaphase
400
Shape of DNA during interphase (cell is not dividing)
What is chromatin
400
In animal cells this is a pinch in the cell at the start of cytokinesis
What is a cleavage furrow
400
Term used that describes when cancer cells break free from original source and spread elsewhere in body
What is metastasize
500
Part of cell growth when the cell is making new organelles in preparation for cellular division
What is G2 phase
500
nuclear membrane and nucleolus disappear
What is prophase
500
A pair of chromosomes (one from mom and one from dad) that are the same size and carry choices for the same trait
What is homologous chromosomes
500
A fanlike microtubule structure that helps separate the chromosomes
What is spindle fiber
500
Test used by scientists to tell whether cells are cancerous or not
What is the scratch test
