How many daughter cells are produced during mitosisHow many daughter cells are produced during mitosis? Are they haploid or diploid? Two diploid cells
During which phase of mitosis do chromosomes line up in the middle of the cell?Metaphase
How many chromosomes do humans have in their body cells?46 or 23 pairs
When does a cell copy its DNA? Be specific.S-phase of interphase
What kind of cells are made from mitosis?Somatic (body) cells
What happens when the cell cycle is not regulated (out of control)?Cancer
What is the term used to describe a cell that has TWO sets of chromosomes (one from mom and one from dad)? Diploid (2n)
What is the term used to describe cells that have just ONE set of chromosomes?Haploid (n)
Name the phases of mitosis in order.Prophase, metaphase, anaphase, telophase
During which phase of mitosis does chromatin condense into chromosomes?prophase
During which phase of mitosis do spindle fibers pull sister chromatids apart?anaphase
What is the process when the parent cell is cleaved into two new daughter cells?cytokinesis
During which phase of mitosis does the nuclear envelope begin to reappear?Telophase
What is the phase where cell growth occurs?G1 and G2 of interphase
What is the process in which gametes are produced?Meiosis
What phase is represented by the picture?Prophase
What phase is represented in the picture?Metaphase
What phase is represented in the picture?Anaphase
What phase is represented by the picture?Telophase
How many cell divisions are involved in meiosis?2
What are the organelles that produce spindle fibers?Centrioles
When does the process of crossing-over occur?Prophase 1
Why does crossing-over occur?To increase genetic diversity
During what process of meiosis do homologous chromosomes line up in the center of the cell?Metaphase 1
At the end of meiosis 1 how many cells are produced?2
During which phase of meiosis are sister chromatids pulled apart?Anaphase 2
During which phase of meiosis do homologous chromosomes get separated?Anaphase 1
If a cell begins meiosis with 34 chromosomes, how many will the resulting four cells have?17
A picture of an organism’s chromosomes in a mitotic cellWhat is a karyotype? A picture of an organism’s chromosomes in a mitotic cell
What are all chromosomes besides sex chromosomes referred to as?Autosomes
What are a male’s sex chromosomes?XY
What are a female’s sex chromosomes?XX
What two things can be determine by analyzing a karyotype?Gender and genetic disorders
What is the structure that holds sister chromatids together?Centromere
What genetic disorder is shown in this karyotype?Down Syndrome
What is Turner Syndrome?When a female is missing one of her X chromosomes
What is Klinefelter Syndrome?When a male has an extra X chromosome
If an organisms diploid cells have 30 chromosomes, how many chromosomes would be in it’s sex cell?15
What is the longest phase of the cell cycle?Interphase
What is the longest phase of mitosis?Prophase
What is spermatogenesis?The production of sperm cells
The production of egg cellsWhat is oogenesis? The production of egg cells
What is the purpose of mitosis?To produce more body cells
What is the purpose of meiosis?To produce sex cells
Describe cytokinesis in plant cells.Cell plate forms midway between the divided nuclei
What phase of meiosis does the picture represent?Anaphase 1
What phase of meiosis does the picture represent?Metaphase 1
How many cells are produced from meiosis? Are they haploid or diploid?Four haploid cells
What phase of meiosis is represented in the picture?Telophase 2
Chromosomes and Cell Division. Chromosomes Your somatic cells (all excluding egg and sperm cells) contain 46 chromosomes Chromosomes contain the genetic.
What do the terms “haploid” and “diploid” mean?
Chapter 8 Cell Reproduction.
The Cell Cycle.
Chapter 6 Chromosomes and Cell Reproduction
1. 2 Cell Cycle… Does your cell cycle look something like this? 3.
1 This is Jeopardy Cell Reproduction 2 Category No. 1 Category No. 2 Category No. 3 Category No. 4 Category No Final Jeopardy.
Karyotype A picture of the chromosomes from a human cell arranged in pairs by size First 22 pairs are called autosomes Last pair are the sex chromosomes.
