Cells are in this phase in the absence of a growth signal.
What is G0?
100
Long, thin fibers of DNA and proteins
What is chromatin?
100
Here, chromosomes are unwinding and become enclosed in the nucleus, as the cell ends division.
What is telophase?
100
In HeLa cells, the number of chromosomes before mitosis = 46. The number of chromosomes at end of mitosis in each of the two new HeLa cells =
What is 46?
100
This forms in between the two new daughter plant cells during cytokinesis.
What is a cell plate?
200
DNA replicates in this phase.
What is the S phase?
200
One half of a duplicated chromosome
What is a sister chromatid?
200
In this phase, duplicated chromosomes are lined up on the cell's equator
What is metaphase?
200
Number of cells produced during one cell division
What is 2?
200
Animal cells use this structure to complete their cytoplasmic division.
What is a cleavage furrow?
300
The cell grows, replicates its DNA, and carries out normal activities prior to entering division (mitosis) phase.
*Reworded for clarity.
What is Interphase (g1, s, g2).
300
Holds two sister chromatids together
What is a centromere?
300
Here, the cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell.
What is prophase?
300
Number of times a cell divides in each cell cycle
What is once?
300
Prokaryotic cells divide by this process.
What is binary fission?
400
The stage that includes G1, S, and G2.
What is interphase?
400
Visible structure seen beginning in prophase
What is a condensed chromosome?
400
In this phase, chromatids are pulled apart and become individual chromosomes
What is anaphase?
400
Number of nuclei in a cell if it doesn't finish cytokinesis?
What is 2?
400
Eukaryotic cells use these two steps to divide.
What are mitosis and cytokinesis?
500
Cell grows again after DNA replication in final preparation for division.
What is the G2 phase?
500
Nucleic acid that makes up the bulk of a chromosome
What is DNA?
500
Mitotic spindle fibers appear and attach to centromeres in this phase.
What is prophase?
500
Number of chromatids on a chromosome in G1 phase and number of chromatids on a chromsome in G2 phase?
What are 1 chromosome with 0 chromatids in G1(we don't technically have a chromatid until after DNA replication in S phase) and 2 chromatids per chromosome in G2?
*Re-read this question/answer carefully. The duplicated chromsomes stays that way until the sister chromatids split apart (and become single CHROMOSOMES again) in anaphase of mitosis.
