Question
Chapter 12, Problem 7RQ
Summary Introduction
To review:
The important considerations for the construction of a plasmid synthesizing His6 (histidine)-tagged protein.
Introduction:
A circular double-stranded DNA (deoxyribonucleic acid) molecule that replicates independently is known as a plasmid. Plasmids exist naturally in bacterial cells to provide special benefits like antibiotic resistance. His6-tagged proteins can be identified by the presence of a string of histidine residues that can bind to nickel under suitable environment.

4. This question focuses on entrainment.
a. What is entrainment?
b. What environmental cues are involved in entrainment, and which one is most influential?
c. Why is entrainment necessary?
d. Assuming that a flash of darkness is an effective zeitgeber, what impact on circadian
rhythms would you expect to result from an event such as the 2024 solar eclipse (assume
it was viewed from Carbondale IL, where totality occurred at about 2 pm)? Explain your
reasoning. You may wish to consult this phase response diagram.

e. Finally, give a real-world example of how knowledge of circadian rhythms and
entrainment has implications for human health and wellbeing or conservation biology.
This example could be from your reading or from things discussed in class.
Generate one question that requires a Punnet Squre to solve the question. Then show how you calculate the possibilities of genotype and phenotype
