6
Condensed chromatin, two sister chromatid linked by a _____
Chromosome / Centromere
7
• The ___ is the period when the cell is in a non-dividing state • This phase is dedicated to the growth, preparations, DNA synthesis, and replication
Interphase
8
•The ____ is the phase in the cell cycle that is highlighted by chromosomal separation resulting into two identical sets in two nuclei.
Mitotic Phase
9
• Chromosomes condense and become visible • Nuclear envelope breaks down • Spindle fiber forms
Prophase
10
• Chromosomes line up at the center of cell • Spindle fibers align chromosomes
Metaphase
11
• Chromosomes are pulled apart • Sister chromatids separates and move to the opposite poles • Spindle fibers contract
Anaphase
12
• Nuclear envelope reforms • Chromosomes uncoil and becomes less visible • Formation of cleavage furrow
Telophase
13
• Final stage of cell division • Cytoplasm divides and cell splits into two daughter cell.
Cytokinesis
14
• Nuclear envelope reforms and cytoplasm divides
Telophase II
15
• Sister chromatids separate
Anaphase II
16
• Sister chromatids line up at the metaphase plate
Metaphase II
17
Nuclear envelope breaks down
Prophase II
18
Non-reproductive cell, has two sets of chromosome (diploid-2n)
Somatic Cell
19
Reproductive cell, has only one set of chromosome (haploid-n)
Gametes
20
This mix and match of chromosomes establishes diversity in the gene pool. The formation of gametes is known as __.
Meiosis
21
The main goal of ___ is to take a diploid cell, reduce its chromosome number to produce haploid daughter cells. ___ accomplishes this by performing steps similar to Mitosis. ____ features two (2) specific stages referred to as ___ and ___
