Answer:
The correct answer is - DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
Explanation:
The chromatin reticulum is present in the undivided cells, which condenses to form a rod-like form called a chromosome. The chromosome consists of DNA structures.
That DNA is a double helical structure and acidic in nature and it is present inside the chromosomes as it is coiled around histone protein which is basic in nature. That allows the DNA to fits in the nucleus.
Thus, the 3rd statement is the correct answer.

Answer:
Sugar molecules do NOT provide all the elements needed to make the four types of macromolecules.
Explanation:
This is because proteins, and amino acids need more types of elements than carbohydrates and lipids do. In nucleic acids, the elements are carbon, hydrogen, oxygen, nitrogen, and phosphorus. Notice that sugar molecules do not have either nitrogen or phosphorus. This same principle applies to proteins, which the elements of it are carbon, hydrogen, oxygen, and nitrogen.
