---|---|---|---|---|---|
Stage 1: Interphase | The first stage of the Cell Cycle; the period before Cell Division; during this, the cell grows, makes a copy of its DNA, and prepares to divide into 2 cells; 2 cylindrical structures called centrioles are also copied
🗑
|
||||
What is Mitosis? | The stage during in which the cell's nucleus divides into 2 new Nuclei; 1 copy of the DNA is distributed into each of the 2 daughter cells
🗑
|
||||
Stage 2A of Mitosis: Prophase | Chromatin in the nucleus condenses to form chromosomes; The pairs of centrioles move to opposite sides of the nucleus; Spindle Fibers form a bridge between the ends of the cell; the nuclear envelope breaks down
🗑
|
||||
Stage 2B of Mitosis: Metaphase | The chromosomes line up across the center of the cell; each chromosome attaches to a Spindle Fiber at its centromere
🗑
|
||||
Stage 2C of Mitosis: Anaphase | The Centromeres split; The 2 chromatids separate; 1 chromatid is drawn by its Spindle Fiber to one end of the cell; the other chromatid moves to the opposite end; the cell stretches out as the opposite ends are pushed apart
🗑
|
||||
Stage 2D of Mitosis: Telophase | The Chrosomes begin to stretch out and lose their rodlike appearence; a new nuclear envelope forms around each region of chromosomes
🗑
|
||||
Stage 3: Cytokinesis | The cytoplasm divides; the organelles are distributed into each of the 2 new cells
🗑
|
||||
The Structure of DNA | There is a DNA ladder made up of molecules of a sugar (deoxyribose) and it alternates with molecules known as phosphates; each rung is made up of a pair of molecules (nitrogen bases- Thymine, Guanine, Cytosine, and Adenine; T&A, A&T, G&C, C&G)
🗑
|
||||
The Replication Process | Begins when the 2 sides of the DNA molecule unwind and separate; Because of the way in which the nitrogen bases pair with one another, the order of the bases in each new DNA moloecule exactly matches the order in the original DNA molecule

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
