Similarities between dna and rna what are the similarities and differences between dna and rna?

similarities:

1- both are nucleic acids ( made up of nucleotides )

2- each nucleotide is formed of sugar ring, phosphate group and nitrogenous base.

3- both of them contain the nitrogenous bases adenine, cytosine and guanine.

differences:

1-DNA is longer

2-DNA is the storage form of all genes while RNA has 3 types. messenger RNA which is a message of certain codes,  ribosomal RNA which enters in the structure of ribosomes (synthesize proteins) and transfer RNA which carries amino acids and helps in transcription process.

3-DNA contains thymine base while RNA contains uracil

4- DNA is more stable and not easily hydrolyzed.
