Question

how does rna differ from dna? responses dna nucleotides are made of pyrimidines, rna nucleotides are made of purines dna nucleotides are made of pyrimidines, rna nucleotides are made of purines dna encodes hereditary information; rna does not. dna encodes hereditary information; rna does not., dna forms linear strands; rna forms circular strands. dna forms linear strands; rna forms circular strands., dna contains deoxyribose, rna contains ribose

Answer 1

DNA has the pyrimidine thymine; RNA has the pyrimidine uracil. The deoxyribonucleotide units of DNA contain 2 deoxy-D-ribose sugar, and the ribonucleotide units of RNA contain D-ribose sugar; the difference lying in absence of an oxygen atom at 2’ position, not in number of carbon atoms.
