Read the passage given below and answer the following question.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two types of nucleic acids found in living systems. DNA acts as the genetic material in most of the organisms. RNA though it also acts as a genetic material in some viruses, mostly functions as a messenger. RNA has additional roles as well. It functions as adapter, structural, and in some cases as a catalytic molecule.The chemical structure of a polynucleotide chain (DNA or RNA). A nucleotide has three components – a nitrogenous base, a pentose sugar (ribose in case of RNA, and deoxyribose for DNA), and a phosphate group. There are two types of nitrogenous bases – Purines and Pyrimidines . .

Which of the following criteria a molecule must fulfill to act as a genetic material? (Question 2)

All of these.

The correct answer is option (4) - All of these

For a molecule to act as genetic material, it needs to fulfill several criteria:

1. It should be able to generate its replica: This is essential for the transmission of genetic information from one generation to the next. Replication ensures that genetic information is passed on during cell division.
2. It should be stable chemically and structurally: Stability is crucial to ensure that the genetic material remains intact and functional over multiple generations. Chemical and structural stability prevent random mutations or degradation.
3. It should be able to express itself in the form of Mendelian characters: The genetic material should be able to carry and express the information that determines the traits (Mendelian characters) of an organism.

So, the correct answer is: All of these.
