The Basics
A(n) ______________ is the smallest structural and functional unit of an organism.
What is a cell?
In this stage the chromosomes line up in the middle of the cell.
What is metaphase?
Four daughter cells, or ______________ cells are produced as a result of meiosis.
What are haploid cells?
The genetic offspring (daughter cells) are exactly like the parent cell.
Any cells other than germ cells are known as non-sexual or ______________ cells.
What are somatic cells?
What is meiosis?
Chromosomes replicate themselves in this stage of mitosis.
What is prophase?
By the end of Meiosis I (and the beginning of Meiosis II), there are this many daughter cells.
What are two?
Creates two new diploid cells.
What is mitosis?
Interphase is known as the resting stage of cell division, when no DNA exchange for cell division takes place. It makes up the majority of the ___________________, or lifespan of the cell.
What is the cell cycle?
The structures that become TIGHTLY PACKED during cell division are known as ________________.
What are chromosomes?
Centrioles are located inside the _________________.
What is the centrosome?
This stage of meiosis is almost identical two mitosis, except for two daughter cells dividing instead of one.
What is Meiosis II?
The structure in a chromosome that holds the two chromatids together is a(n) __________________.
What is the centromere?
There is a one paternal chromosome pair and one maternal chromosome pair during inside the parent cell during meiosis. These chromosome pairs are known as ______________________.
What are homologous chromosomes?
The ______________________ control the movement and separation of chromosomes during parts of mitosis and meiosis.
What are spindle fibers?
This main stage of mitosis results in two new daughter cells being formed.
What is telophase?
The resting stage between Meiosis I and Meiosis II.
What is interkinesis?
DNA replication
What is both?
In ______________, new daughter cells are not genetically the same as each other or the parent cell.
What is meiosis?
The process where homologous chromosomes pair up and EXCHANGE genetic material is known as ____________________.
What is crossing over?
In anaphase, the cell elongates and the _____________________ move toward the poles.
What are chromosomes?
Duplication of homologous chromosome pair and
cross-over occurs.
What is Prophase I?
Two identical copies of a chromatid are known as ___________________.
What are sister chromatids?
In this stage of mitosis and/or meiosis II, the spindle fibers pull apart the two sister chromatids of each chromosome.
What is anaphase (mitosis) and anaphase II (meiosis II)?
