BSC 1010L FINAL EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS GRADED A++ LATEST
UPDATE
What are the phases of the cell cycle?
G1, S, G2, (interphase)
What are the steps of mitosis?
prophase, metaphase, anaphase, telophase
Prophase
Nuclear envelope dissolves and DNA condense
Metaphase
Chromosomes line up in the middle of the cell, spindle fibers attach
Anaphase
chromosomes separate and move to opposite ends of the cell
Telophase
nuclear envelope reforms
What is the end result of mitosis?
After cytokinesis, we have two identical cells
What is the difference between mitosis and meiosis?
meiosis goes from diploid to haploid. Meiosis creates genetic variation. Any ploidy can
do mitosis.
, What does meiosis I and II result in?
Meiosis I: two haploid cells with duplicated chromosomes
Meiosis II: 4 genetically unique cells
What is diploid and haploid?
Having 1 or 2 sets of each kind of chromosome
What steps is between meiosis 1 and 2?
Interkinesis
Embryonic stem cells
pluripotent cells that come from the blastocyst stage a week after fertilization. They are
controversial because these cells could have been used to develop a new human life.
Adult stem cells
Multipotent cells that come from adult tissue, so they are not controversial. Can
potentially be used to treat diseases, but are difficult to isolate
Cord Blood-derived Embryonic-like Stem Cells (CBEs)
Multipotent cells, but they have pluripotent abilities. They come from the umbilical cord
after birth, so they are not controversial
induced pluripotent stem cells
Pluripotent cells that are derived from adult cells that have been genetically altered.
They are not controversial
What is pluripotent and multipotent?
Pluripotent cells can become any other cell type except those used to create a fetus.
Multipotent cells can be used to create some cells types because they are
differentiated.
