100
The first phase in a cell life cycle where the cell grows to size.
What is G1 Phase?
100
The first phase of mitosis where the nuclear envelope dissolves and spindle fibers form.
What is prophase?
100
What is prophase?
100
The idea that a normal cell becomes specialized throughout its life.
What is cell differentiation?
100
Number of chromosomes in a cell after duplication in the S phase.
What is 46?
200
The second phase in the cell life cycle where DNA is duplicated.
What is the S stage?
200
The second phase of mitosis where the chromosomes begin to line up in the middle of the cell.
What is metaphase?
200
What is metaphase?
200
When a phenotype or characteristic of a cell is seen because of a certain gene.
What is gene expression?
200
Number of chromosomes in a cell after the full cell cycle and mitosis is complete.
What is 23?
300
The third phase in the cell life cycle where the cell prepares to divide.
What is G2 phase?
300
The third phase of mitosis where the spindle fibers begin to pull the chromatids towards opposite ends of the cell.
What is anaphase?
300
What is anaphase?
300
When certain genes in a cell are turned off if the cell does not need them to preform their specialized task.
What is gene regulation?
300
A plant cell forms this instead of a cleavage furrow during telophase and cytokinesis.
What is a cell plate?
400
The life cycle phase the cell is in for majority of its life (it is the first 3 phases combined).
What is interphase?
400
The fourth and final phase of mitosis where the cleavage furrow forms and the nuclear envelope begins to reform around the DNA.
What is telophase?
400
What is telophase?
400
The name of process that controls gene regulation. (HINT: occurs in the S phase of the cell life cycle.)
What is transcription?
400
The cell structure that pulls the chromatids apart during mitosis.
What is a spindle fiber?
500
The fourth phase of the cell life cycle where the divsion takes place.
What is mitosis?
500
The phase after mitosis where the cells officially divide.
What is cytokinesis?
500
What is cytokinesis?
500
The level of transcription increases or decreases on certain parts of the gene.
How transcription causes gene regulation?
500
The part of a chromatid that the spindle fiber attaches to.
What is a centromere?
