Bio Sci 93: DNA to Organisms (UCI) Final
When does crossing over take place? ANSWER between non-sister chromatids
during Meiosis I
Answer: Crossing Over One method (which resembles a tiny switch or tag) that
creates genetic diversity during meiosis
At what point is nondisjunction possible? - ANSWER 1. Mitosis Anaphase 2.
Meiosis Anaphase I
3. Meiosis Anaphase II
Answer: Nondisjunction Because a centromere breaks or a spindle fails to
adhere, chromosomes cannot properly segregate to opposite poles during
anaphase.
ANSWER: Anaploidy Two sister chromatids end up in one location or pole
during mitosis.
ANSWER: Random Fertilisation Another source of genetic variety in kids is
the millions of possible gametes that can be produced from the two combined
parent gametes.
Barr Bodies: ANSWER The female somatic cell's dormant X chromosome
The answer to the Law of Independent Assortment Independent of the members
of other genes, members of a particular gene pair separate from one another.
The sodium-potassium "pump" function is to transfer potassium ions (2) into the
cell and sodium ions (3) out of the cell. In opposition to its concentration
