Expert Solution & Answer

Summary Introduction
To explain: The comparison between mitosis and meiosis.
Concept introduction:
Mitosis is a type of cell division where two daughter cells are formed by the separation of a newly duplicated DNA. As the process is an asexual mode of reproduction, it plays an important role in single-celled eukaryotes. Meiosis is another type of cell division that decreases the chromosome number by half,which results in four haploid cells, each daughter cell will be genetically distinct from the parent cell.
Explanation of Solution
Both mitosis and meiosis are associated with cytokinesis. The results of the two processes will be daughter cells. The sequence of events in mitosis and meiosis is same but in meiosis it occurs twice. The processes differ in two ways. Meiosis undergoes genetic separation and cellular division twice, while the mitosis has only one cycle.
Completed table is given below:
Mitosis | Meiosis | |
Number of chromosomal duplications | 1 | 1 |
Number of cell divisions | 1 | 2 |
Number of daughter cells produced | 2 | 4 |
Number of chromosomes in daughter cells | 46 | 23 |
How the chromosomes line up during metaphase | line up as single chromosomes in the middle | pair of homologous chromosomes lined up at the metaphase plate |
Genetic relationship of daughter cell to parent cell | Identical | Different |
Function performed in human body | Somatic cells | Reproductive cells |
- Number of chromosomal duplications:In both mitosis and meiosis, the cell duplicates its chromosomesonly once. Hence, 1 is the correct answer for both mitosis and meiosis.
- Number of cell divisions: Only one cell division occurs in mitosis, whereas two cell divisions occurs during meiosis called meiosis І and meiosis ІІ. Hence, 1 is the answer for mitosis and 2 for meiosis.
- Number of daughter cells produced: Meiosis results in four haploid daughter cells, whereas mitosis gives two identical diploid cells. Hence, 2 is the correct answer for mitosis and 4 is the correct answer for meiosis.
- Number of chromosomes in daughter cells: A mitotic daughter cell contains 46 chromosomes (diploid), whereas a meiotic daughter cell contains 23 chromosomes (haploid). Hence, 46 is the correct answer for mitosis and 23 is correct answer for meiosis.
- How the chromosomes line up during metaphase: Mitosis line up as single chromosome in the middleof the cell; while in meiosis, a pair of homologous chromosomes lines up at the metaphase plate. Hence, the correct answer for mitosis is line up as single chromosomes in the middle and for meiosisis a pair of homologous chromosomes lined up at the metaphase plate.
- Genetic relationship of daughter cell to parent cell: The daughter cells are identical to parents in mitotic division; whereas in meiosis, the daughter cells are different. Hence, the correct answer for mitosis is identical and for meiosis isdifferent.
- Function performed in human body: Mitosis results in somatic cells, whereas reproductive cells are formed as a result of meiosis. Hence, the correct answer for mitosis is somatic cells and for meiosis is reproductive cells.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions.
1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction?
2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe:
a) What molecule do you recommend for the trial. Why?
b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?
3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale.
4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale.
