• 🇦🇪 The sugar unit in DNA is deoxyribose, while in RNA, it is ribose.
• 🪭 DNA has a double-stranded alpha helix structure, while RNA is single-stranded and folding.
• 🧬 DNA contains cytosine and thymine as bases, while RNA contains cytosine and uracil.
• 🧡 The molar mass of DNA ranges from 6x10^6 to 16x10^6 units, while RNA ranges from 20,000 to 40,000 units.

Questions & Answers

Q: What is the major difference in the sugar unit between DNA and RNA?

DNA contains deoxyribose, while RNA contains ribose. This difference in sugar unit creates distinctions in their structure and function.

Q: What is the difference in structure between DNA and RNA?

DNA has a double-stranded alpha helix structure, while RNA is single-stranded and folding. This structural difference affects their stability and functionality.

Q: What are the bases present in DNA and RNA?

DNA contains cytosine and thymine as bases, while RNA contains cytosine and uracil. The difference in bases contributes to the uniqueness and functionality of each nucleotide.

Q: Can DNA and RNA replicate?

DNA can replicate, while RNA cannot. DNA's ability to replicate is crucial in passing on genetic information, while RNA plays a vital role in protein synthesis.

Summary & Key Takeaways

• DNA stands for deoxy ribose nucleic acid, while RNA stands for ribose nucleic acid. The sugar unit is different in both.

• DNA has a double-stranded alpha helix structure, while RNA is single-stranded and folding.

• DNA contains cytosine and thymine as bases, while RNA contains cytosine and uracil.
