Answer:
The correct answer will be-
1. Chromosomes
2. Nucleus
Step-by-step explanation:
The instructions of the cell to perform its function are provided by the DNA which is the genetic material of the organisms.
The DNA is packaged into a highly condensed structure called chromosomes which contain the genes on its structure which provides the code. These chromosomes are located in a double membrane structure called nucleus which protects the genetic material from the acidic environment of the cell.
Since the chromosomes are made up of the DNA in the nucleus thus, chromosome and the nucleus is the correct answer.
