Cell Cycle
This is the stage for most organisms where most of the life activities occur.
What is GI?
Name the stage of a cell where nuclear membranes begin to break down and chromosomes appear as organized packages of the genome.
What is prophase?
Unlike mitosis, meiosis produces cells with this number of chromosome sets.
What is haploid?
A human body cell has 46 chromosomes. How many chromosomes would a normal human gamete have?
What is 23?
These are the haploid reproductive cells that combine during fertilization.
What are gametes?
Synthesis of DNA occurs here to make a complete copy of the genome.
What is S phase?
In this stage, sister chromatids are pulled apart toward opposite poles of the cell.
What is anaphase?
Meiosis involves two round of division. Name them.
What are meiosis I and meiosis II?
A cell has a diploid chromosome number of 28. How many chromosomes would each cell have after meiosis?
What is 14?
This process produces sperm cells?
What is spermatogenesis?
This is a resting phase. Some cells enter this phase permanently.
What is G0?
A cell has chromosomes that look like an "X" and are lined up across the center of the cell. What stage is occuring?
What is metaphase?
At the end of meiosis I, homologous chromosomes have separated, but the sister chromatids are still attached. What happens next?
What is meiosis II, prophase II?
A cell has 28 chromosomes and undergoes mitosis. How many daughter cells are produced, and how many chromosomes does each daughter cell contain?
What are 2 cells, each with 28 chromosomes?
This process produces egg cells.
What is oogenesis?
A cell spends most of its life in this part of the cell cycle, even though it is often overlooked when studying cell division.
What is interphase?
This stage occurs after the sister chromatids have separated. New nuclear membranes begin forming around the chromosomes.
What is telophase?
A cell begins meiosis with 8 pairs of homologous chromosomes. How many chromosomes will each cell have after meiosis I?
What is 8 chromosomes?
A cell has 28 chromosomes and undergoes meiosis. How many cells are produced, and how many chromosomes does each cell contain?
What are 4 cells, each with 14 chromosomes?
One cell undergoes spermatogenesis. How many functional gametes can result?
What is 4?
This happens to a cell if it cannot pass one of the 3 very important checkpoints. It is considered the death of a cell.
What is apoptosis?
A plant cell is finishing mitosis. Instead of forming a contractile ring that pinches the cell in two, it begins building a structure between the two new cells. What is forming?
What is a cell wall?
A cell begins meiosis with 8 pairs of homologous chromosomes. After meiosis II is complete, how many cells are produced, and how many chromosomes are in each?
What are 4 cells with 8 chromosomes each?
A cell begins meiosis with 12 pairs of homologous chromosomes. How many chromosomes are present in each cell after meiosis I? How many will each cell have after meiosis II?
What is 12 chromosomes after meiosis I and II?
One cell undergoes oogenesis. Four cells are technically produced through meiosis, but only one becomes a functional egg. How many functional gametes result?
What is 1?
