Answer:
a."Alkylating agents are toxic to tissues that have rapidly dividing cells."
Explanation:
In the given example the patient is about to begin chemotherapy with a bifunctional alkylating agent.
when the two dna strands are cross linked they will not separate for dna replication which will halt the cell division process so rapidly dividing cells will stop dividing and die
Moreover,Chemotherapeutic agents, also known as antineoplastic agents, are used to prevent the growth of fast-growing cells, usually in the sense of malignancy, directly or indirectly.
Therefore, Chemotherapeutic agents are Alkylating agents that are toxic to tissues that have rapidly dividing cells
So, this statement by student indicates an understanding of his chemotherapeutic agent.

Explanation:
The respiratory system is a collection of organs involved in carrying out gas exchange in your body. Deep in the lungs, tiny sacs called alveoli take in oxygen from the atmosphere and release carbon dioxide.
Answer: Histones and DNA have opposite charges -True
Acetylation of histones cancels their positive charge- True
Acetylated histones are more attracted to DNA - False
Acetylation creates binding sites for remodeling engines and other factors- True
Explanation:
It is widely found that acetylation of lysines leads to transcriptional activation. The modifications of histones such as acetylation affect the affinity of the histone for interacting proteins that control the transcriptional activity of chromatin,
which has led to the concept of a histone code.The positive charge on the histones is removed by acetylation, hence they decrease the interaction of histones with the negatively charged phosphate groups of DNA. As a result, the highly condensed chromatin is now transformed to a more relaxed structure and thereby higher level of transcription are achieved
