Answer :
DNA is double-stranded, contains deoxyribose sugar, and uses thymine; RNA is single-stranded, contains ribose sugar, and uses uracil.
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are both nucleic acids crucial for genetic information storage and expression in living organisms. While sharing similarities, they exhibit distinct differences. DNA is typically double-stranded, forming the iconic double helix, and its sugar is deoxyribose. DNA employs four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The complementary base pairing ensures specificity (A with T, and C with G).
On the other hand, RNA is usually single-stranded, with its sugar being ribose. RNA uses uracil (U) instead of thymine as a base, and its primary types include messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA carries genetic information from DNA to ribosomes for protein synthesis, tRNA brings amino acids to the ribosome, and rRNA forms a structural component of ribosomes.

Final answer:
DNA and RNA can be compared using a Venn diagram. DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose. Both DNA and RNA play a role in hereditary information.
Explanation:
Comparison of DNA and RNA using a Venn Diagram
The Venn diagram can be used to compare and contrast DNA and RNA. Here are some key points:
- DNA: Found in the nucleus, carries genetic information, double-stranded, contains the sugar deoxyribose, uses the bases A, T, C, and G.
- RNA: Found in the nucleus and cytoplasm, carries instructions for protein synthesis, single-stranded, contains the sugar ribose, uses the bases A, U, C, and G.
- Both DNA and RNA: Made up of nucleotides, contain phosphate groups, involved in hereditary information.
