What is the major structural difference between dna and rna

Quick Answer. DNA is double-stranded, while RNA is single-stranded. RNA contains ribose as a sugar, while DNA contains deoxyribose. Also, three of the nitrogenous bases are the same in the two types (adenine,thymine, cytosine, and guanine), but DNA contains thymine while RNA contains (adenine,uracil cytosine,and guanine)

The DNA or deoxyribonucleic acid structure looks like a twisted leader; also the description of the structure of the DNA molecules is what is known as the double helix. The structure of the RNA looks like a hairpin, it is where the nucleotides are formed: it is made up of a single strand

The structure of DNA has a double strand with two nucleotide strands that are made up of phosphate group, a sugar and a nitrogen base.

The nitrogen is also categorized into five types, which include adenine (A), thymine (T), guanine (G) and cytosine (C). The way the hydrogen bases are arranged is what determines genetic code. However, DNA was discovered in 1869 by Frederich Miescher

RNA or ribonucleic acid is single-stranded and is comprised of the phosphate group, a five-carbon sugar and four nitrogen-containing nucleobases which are adenine, Guanine, Cytosine. The main building blocks in the RNA are Adenine and uracil and they form base pair.

The structure of the RNA looks like a hairpin where the nucleotides are formed. The RNA helps in the translation of DNA to proteins and also serves as an adapter molecule protein synthesis.

Therefore, DNA is made up of a double strand, and RNA is made up of a single strand
