DNA contains one strand, RNA contains two

|
|
DNA contains uracil, RNA contains thymine
|
|
|
DNA contains deoxyribose, RNA contains ribose

|
|
DNA is made up of nucleotides, RNA is not
|
Detailed explanation-1: -The deoxyribose sugar of DNA contains one less oxygen-containing hydroxyl group. DNA is a more stable nucleic acid. RNA, on the other hand, contains ribose sugar and is more reactive than DNA. Therefore, DNA is a better genetic material than RNA.
Detailed explanation-2: -There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
Detailed explanation-3: -Thus, the major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation.
Detailed explanation-4: -Summary of Differences Between DNA and RNA DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.
Detailed explanation-5: -So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
