Answer:

(B)  Chromosomes are made of DNA.

Explanation:

i took the test <3

Chromosomes are made of DNA which shows the relationship between a chromosome and DNA. So, the correct option is B.

A chromosome is indeed a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.

Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule. Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure. The fact that DNA is a component of chromosomes demonstrates the connection between chromosomes and DNA.

Therefore, the correct option is B.

There are also different families such as the noble gases and alkali earth metals. The elements are placed where they are because of the atomic number which is directly equal to the number of protons there are. The atomic mass is the number of both protons and neutrons. Also, even though the number of protons can be equal to the number of electrons, that isn't always the case. It could be an isotope which is basically for when an element or atom isn't neutral.
