Miscellaneous
Threadlike structures made of DNA molecules that contain the genes.
What are chromosomes?
The longest stage of Mitosis
What is Prophase?
The process when an egg and sperm meet.
What is fertilization?
The phase of the cell cycle when DNA replication take place
What is S phase?
Term for 2n
What is a diploid?
The three main reasons why cells divide.
What is growth, repair, and reproduce?
This phase is used to view the structure and number of chromosomes under a microscope.
What is Metaphase?
The structure, in which, the homologous chromosomes match up.
What is a tetrad?
Enzyme that unwinds the DNA
What is a helicase?
A double membrane across the midline of a dividing plant cell, between which the new cell wall forms during cytokinesis.
What is a cell plate?
The appearance of the chromosomal makeup of a somatic cell in an individual or species (including the number and arrangement and size and structure of the chromosomes)
What is a Karyotype?
The stage in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosome.
What is Telophase?
4 daughter cells are produced after this phase.
What is Telophase II and Cytokinesis?
Base pairing:
AGTCAG
What is TCAGTC?
A cellular protein that occurs in a cyclically fluctuating concentration and that plays an important role in regulating the cell cycle.
What is a cyclin?
The process in which prokaryotes (bacteria) reproduce.
What is binary fission?
During prophase the nucleoli disappears, chromosomes condense, centrosomes move away from each other, and this begins to form.
What are spindle fibers?
When chromosomes fail to separate equally during meiosis
What is nondisjunction?
Seals the Okazaki fragments together
What is ligase?
The phenomenon observed in normal animal cells that causes them to stop dividing when they come into contact with one another.
What is density dependent inhibition?
If conditions are not appropriate for the cell to divide or if it is not programmed to divide they are in this phase
What is the G0 phase?
If cells in the process of dividing are subjected to colchicine, a drug that interferes with the functioning of the spindle apparatus, at which stage will mitosis be arrested
What is metaphase?
After telophase I of meiosis, the chromosomal makeup of each daughter cell is
What is haploid, and the chromosomes are each composed of two chromatids?
The name of the proteins that DNA wraps around in order to condense
What are histones?
Produces elongation of the cell as they slide past each other away from the middle of the cell (anaphase).
What are nonkinetochore microtubules?
