Question

what is the structural difference between DNA and RNA

Answer 1

The structural difference between DNA and RNA:

DNA

• DNA is a molecule having double strands containing deoxyribose sugar and hence referred to as Deoxiribo Nucleic Acid.
• Since it has two strands, it forms a double helix.
• It has a nucleotide chain that is very long.
• DNA is stable because of the C-H bonds present in them.

RNA

• RNA is a molecule having only a single strand containing ribose sugar and hence referred to as Ribo  Nucleic Acid.
• Since it has only one strand, it forms a helix.
• It has a nucleotide chain that is very short.
• RNA is reactive because of the O-H bond present in them.

Answer 2

Answer:

The structural difference between DNA and RNA are:

• DNA is a double stranded molecule wheras RNA is a single strand molecule.
• DNA has deoxyribose sugar and RNA has ribose sugar.
• DNA has nitrogen base adenine, guanine, cytosine, and thymine wheras in RNA in place of thymine there is uracil.
• Due to the presence of uracil RNA is more reactive than DNA and hence it shows more variations.
