The Cell Cycle
During which phase of the cell cycle does the cell grow in size
G1 (I'll take G2, as well)
Name the order in which the phases of mitosis occur:
Prophase, Metaphase, Anaphase, Telophase (Cytokinesis)
What cells go through meiosis?
Sperm and egg cells (gametes)
Humans have 46 of these strands of DNA, curled up into X shapes
Chromosomes
What is another, more scientific name for sperm and egg cells?
Gametes
During which phase of the cell cycle is DNA replicated?
S Phase
In this phase of mitosis, the chromatin condenses and winds up, to become visible chromosomes
Prophase
How many daughter cells are produced in meiosis?
4
This form of DNA is basically an unwound chromosome, that looks like an unwound mess of noodles. This is seen in Interphase
Chromatin
A body cell has a full set of chromosomes. We call this a ________ cell
Diploid
During which phase of the cell cycle does the cell divide?
Mitosis
In this phase, the chromosomes line up in the middle of the cell
Metaphase
If a human has 46 chromosomes, how many chromosomes would a gamete (such as sperm or egg cells) have?
23 chromosomes
This is an identical half of a chromosome
Chromatid
Haploid
Which 3 phases of the cell cycle are involved in Interphase?
G1, S Phase, G2
In this phase, chromosomes pull apart into chromatids, so each new cell will have identical information to function
Anaphase
Why does meiosis occur in the body?
reproduction
In prophase 1, chromosomes pair up. What are these pairs called?
Homologous chromosomes
The strings that connect to the chromosomes in metaphase are called what?
Spindle Fibers
What phase of the cell cycle takes up 90% of a cells lifespan?
Interphase
What are 2 reasons mitosis happens in the body?
Growth and repair
What process in prophase 1 causes DIFFERENT daughter cells to be produced each time meiosis occurs?
Crossover
What is the center point of a chromosome called?
Centromere
The "Motors" on either end of the cell that pull spindle fibers, and tear the chromosomes apart are called...
Centrioles
