 * __Vocabulary For Cell Cycle, Mitosis and Meiosis__**

__ **5.What is similar about the cell cycle and meiosis?** __ ** - The cell cycle and meisosis both sperates its chromosomes and divides it into two daughter cells. **  ** - The first step of Interphase, which is copying the chromosomes are the same. **  ** - Same events happen to the **** DNA, Chromosomes, and Chromatids at each step. **  ** Cell Cycle **
 * ** Chromatid ** || One of the two identical copies of DNA making up a duplicated chromosome, which are joined at their centromeres, for the process of cell division || [[image:Chromatid.jpeg width="148" height="120"]] ||
 * ** Identical ** || Exactly the same || [[image:Unknown.jpeg width="133" height="133"]] ||
 * ** Asexual Reproduction ** || Cell divides into two identical cells with the same DNA || [[image:Asexual_Reproduction.png width="120" height="124"]] ||
 * ** Cell cycle ** || The regular sequence of growth and division that cells undergo || [[image:Cell_cycle.jpeg width="112" height="107"]] ||
 * ** Nucleus ** || Contains nucleic acids, the chemical instructions that direct all the cell’s activities || [[image:Nucleus.jpeg width="134" height="87"]] ||
 * ** Replication ** || Cell making a copy of the DNA in its nucleus || [[image:Replication.jpeg width="215" height="109"]] ||
 * ** Cells produced ** || Cells are produced by cell division || [[image:Cell_Production.jpeg width="129" height="94"]] ||
 * ** Sexual Reproduction ** || Sex cells combining || [[image:Sexual_Reproduction.png width="106" height="153"]] ||
 * ** Centromere ** || Middle of a chromosome where two identical sister chromatids come closest in contact || [[image:Centromere.jpeg width="65" height="157"]] ||
 * ** Variation ** || Any difference between individuals of the same species || [[image:variation.jpeg width="121" height="96"]] ||
 * ** DNA ** || The genetic material that carries information about an organism and is passed from parent to offspring || [[image:DNA.jpeg width="131" height="73"]] ||
 * ** Cell Division ** || Process by which a parent cell divides into two or more daughter cells || [[image:Cell_division.jpeg width="183" height="91"]] ||
 * ** Mitosis ** || The stage of the cell cycle during which the cell’s nucleus divides into two new nuclei and one copy of the DNA is distributed into each daughter cell || [[image:Mitosis.png width="93" height="211"]] ||
 * ** Sex cells ** || Sex cells are also called gametes. The gametes are the sperm and the egg; the more scientific terms for these cells are the spermatozoa and ova || [[image:Sex_Cells.jpeg width="245" height="58"]] ||
 * ** Chromosome ** || Contains DNA that carries genetic information || [[image:Chromosome.jpeg width="124" height="98"]] ||
 * ** DNA Replication ** || Process that occurs in all living organisms and copies their DNA || [[image:DNA_replication.jpeg width="154" height="41"]] ||
 * ** Growth + Repair ** || To grow or grow back or heal || [[image:Growth.jpeg width="141" height="77"]] ||

** Meiosis ** **6. What is different about cell cycle and meiosis?**

** - In mitosis, which is part of the cell cycle, the chromosomes are duplicated before division so each daughter cell receives a full set of two of each chromosomes. In meosis, the chromosomes are not duplicated before division, so each daughter cell only receives one of each chromosomes. Meosis is used to reproductive cells; each sperm and egg cell has half the normal number of chromosomes, so two of them combine to make a cell with the full normal number. **   ** Meiosis = **   ** 1. Different replica **  ** 2. Different **** number and patterns of genes and chromosomes **  ** 3 ****. Sexual reproduction **  ** 4. Divides into 4 cells **  ** 5. Chromosomes are divided in half (23) **  ** 6. Chromosomes crossing over ** ** Mitosis = **  ** 1. Identical replica **  ** 2. Same number and patterns of genes and chromosomes **  ** 3. Asexual reproduction **  ** 4. Divides into 2 cells **  ** 5. Chromosomes are the same (46) **  ** 6. Chromosomes aren't able to cross over ** **Cell cycle and Meiosis Comparison:** media type="file" key="videoplayback copy.flv" width="330" height="330" align="center" http://www.youtube.com/watch?v=N4fcgu2nAyk&feature=related Thank You
