Question
Chapter 2.2, Problem 1TPSQ
Summary Introduction
To explain:
The reason whether the genetic information from two sister chromatids is passed from a single parent or both the parents.
Introduction:
A sister chromatid depicts the chromatid which is formed by a chromosome’s replication. Both the copies are attached to a centromere which is common.
Expert Solution & Answer
Explanation of Solution
Sister chromatid is also known as one half of the chromosome which is duplicated. Dyad is a term which is known for a pair of sister chromatids. A complete set of chromatids (sister) is formed at the time of Interphase synthesis phase, when there is replication of the cell.
The sister chromatids get separated into 2 different cells at the time of meiosis or mitosis. The sister chromatids are large and identical because they carry same alleles of genes as they are derived from a single chromosome. Hence, if a chromosome consist of two sister chromatids, then it is clear that it is derived from a single parent’s original chromosome.
Conclusion
The genetic information from two sister chromatids is passed from a single parent as the sister chromatids are the duplicated chromatids of the original chromosome.

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.
