Question
Chapter 11, Problem 22A
Summary Introduction
To analyze:
An error that occurs during cell division.
Introduction:
Cell division is a part of a cell cycle in which parent cells divide to produce two or more daughter cells. It involves the separation of genetic material into the two daughter cells.
Expert Solution & Answer
Explanation of Solution
Nondisjunction: When homologous chromosomes (meiosis) or sister chromatids (meiosis/mitosis) fail to separate during cell division, then daughter cells are produced with an abnormal number of chromosomes.
Nondisjunction is an error that occurs during cell division.
It results in extra copies of certain chromosomes or only one copy of a particular chromosome in the offspring.
Conclusion
Nondisjunction can result in Trisomy that is a set of three chromosomes of one kind present in the nucleus.
Monosomy is the condition when only one copy of a particular chromosome is present in the nucleus.

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
