1. You intended to make 1000 ml of 5% NaOH (MW = 40) solution, but only found 20 gm of NaOH pellets in the lab. However, you also found a bottle containing 80 ml of 10 M NaOH solution.
a. Was there enough NaOH in the lab for you to make 1000 ml of 5% NaOH solution? Why?
b. If you had enough NaOH, how would you make the 1000 ml of 5% NaOH solution?
c. If the NaOH in the lab was not enough, how much more NaOH (in gram) did you need to make the 1000 ml of 5% NaOH solution?
2. You may have to do some research to answer the following questions. Htz1 (aka H2A.Z) is a histone H2A variant.
a. What is a histone variant?
b. Name at least two other known histone variants.
c. Give an example of a histone variant regulating nucleosome structure/property.
d. Give an example of a histone variant regulating gene expression.
e. Give an example of a histone variant contributing to chromosome segregation during cell division.
f. Give an example of two different histone variants collaborating to regulate the same DNA transaction.
