Homework Answers
1.chromatin
explanation: the primary function of chromatin is to pack very long DNA molecules into a more compact and denser shape. The primary protein components of chromatin are histones,which bind to DNA.
2.chromosomes, nucleus.
explanation: DNA is located in the cell nucleus in the form of chromosome.
3.DNA
explanation: DNA which is the main genetic material for eukaryotes are mostly present in nucleus in the form of chromosome.
4.sister chromatids.
explanation: sister chromatid refers to the identical copies formed by the DNA replication of a chromosome,with both copies joined together by a common centromere. A full set of sister chromatids is created during the S phase of interphase before cell division.
5.centromere.
explanation: The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids.

The calcium ion binds to a certain protein to form a 1:1 complex. When 96μM protein and 60μM Ca2+ are mixed together, the concentration of free ligand (calcium) was found to be 31μM. a. Calculate the dissociation constant of the Ca2+−proteinCa2+−protein complex. b. What concentration of Ca2+Ca2+ would you need to dissolve in the solution to ensure that 95% of the protein is bound to calcium? c. What percentage of the calcium ions are bound to the protein in the...
