Answer:
Molecules are extremely long.
Step-by-step explanation:
The genetic material may be defined as the material that can be transferred from parents to the offspring. DNA is the main genetic material of the living organisms but RNA acts as the genetic material in some viruses only.
The four different bases present in DNA are adenine, thymine, guanine and cytosine. The arrangement of these molecules is quite different in different species that brings variation in the living organisms. The DNA molecule is quite long that encode the information for the entire organisms.
Thus, the answer is molecules are extremely long.
