Final answer:
DNA and RNA both share similarities in their composition and functions such as containing nitrogenous bases and phosphate groups, as well as being involved in various biological processes.
Step-by-step explanation:
Both DNA and RNA contain the nitrogenous bases adenine, cytosine, and guanine. These bases are the building blocks of DNA and RNA and play a vital role in genetic information transmission.
Both DNA and RNA contain phosphate groups on their respective nucleotides. These phosphate groups are important for creating the backbone structure of DNA and RNA.
Both DNA and RNA can transport messages, act as enzymes, and are part of ribosomes. RNA, in particular, plays a crucial role in protein synthesis and gene expression by carrying genetic information from DNA to the ribosomes.
