why DNA is not directly trsnslated into protein rather than
it is using RNA as intermediate?

Answer Posted / akilandeswari

DNA contains a number of introns which are not important for translation. so DNA is converted to mRNA,post transcriptional modifications are done on it, mainly introns are spliced. thus mRNA now will be ready to be translated. there are even polycistronic mRNA from which a number of proteins can be obtained. this property is lacking in DNA.
