Answer: RNA- single stranded
DNA- double stranded
Step-by-step explanation:
RNA or ribonucleic acid is a single stranded molecule. It is a genetic material in living beings. It performs many functions such as expression of genes for a particular function, coding, decoding, and cell metabolism regulation. It is necessary for synthesis of proteins.
DNA is deoxyribose nucleic acid. It is a double stranded molecule. It is also a form of genetic material. It consists of genetic material which is necessary for development, growth, reproduction and orderly functioning of the organism.
