7 Written Questions

1. the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate and spindle fibers connect them to the centrioles.
2. a cell plate forms across the middle of the cell. it gradually develops into new cell membranes between the two daughter cells. New cell walls can then form around the cell membranes.
3. cell grows, prepares to copy DNA, part of interphase
4. the cell makes an exact copy of its DNA
5. area where the chromatids of a chromosome are attached
6. the centromeres spilt, the chromatids separate and become their own chromosomes. the new chromosomes move to the poles of the cell and the cell is stretched apart.
7. connect the chromosomes to the centrioles

3. the chromosomes begin to stretch out and lose their rod-like appearence. A new nuclear envelope forms around each new region of chromosomes
   1. telophase
   2. S phase
   3. Prophase

5. the cell membrane squeezes together around the middle of the cell the cytoplasm pinches into two cells and each new cell gets half of the organelles
   1. 4 nucleic acids
   2. Mitosis
   3. cytokinesis in plant cells
   4. cytokinesis in an animal
6. Adenine, thymine, guanine, and cytosine
   1. replication
   2. spindle fibers

6 True/False Questions

1. haploid # → (genetics) an organism or cell having two sets of chromosomes or twice the haploid number

   True        False

2. diploid # → (genetics) an organism or cell having only one complete set of chromosomes

   True        False

3. Prophase → the first stage of mitosis, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes and the centrioles move to opposite poles of the cell

   True        False

4. Mitosis → the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate and spindle fibers connect them to the centrioles.

   True        False

5. how they are paired → Adenine w/ thymine and Guanine w/ cytosine

   True        False

6. G2 phase → cell continues to grow, proteins and amino acids are produced, part of interphase

   True        False
