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.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
