Answer:
RNA world hypothesis.
Explanation:
RNA is present as the genetic material in some viruses only. RNA is produced from the template DNA by the process of transcription and helps in the protein gene expression.
According to RNA world hypothesis, RNA is considered to be the first genetic material as it has the ability to store the genetic material. The oxyribose sugar makes the RNA more reactive than the DNA molecule. The RNA also has the ability to work enzyme known as ribozyme. Hence, RNA has the ability to store the information and acts as catalyst.
Thus, the answer is RNA world hypothesis.
 
        
             
        
        
        
The chromosome is the one that carries the genetic information. The gene is the basic unit of heredity, meaning, this is the one that we carry from our parents. Genome is the collection of genes that is present in an organism. Therefore, if we arrange this from simplest to the most complex, the arrangement would be GENE, CHROMOSOME, GENOME.
