Hello!

The correct answer is A. A system is a group of objects analyzed as one unit.

We know this because all systems are NOT made by humans, there are numerous ways to define the boundaries of one, and the energy is not necessarily conserved. The parts of a system are analyzed as being apart of that group, which makes A the only correct and rational answer.

I hope I helped! :)

dna damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. dna damage and mutation have different biological consequences. while most dna damages can undergo dna repair, such repair is not 100% efficient.

this protocol provides a detailed procedure for chromatin immunoprecipitation (chip) to study the dna-protein interactions.
