Question

Write the difference between DNA and RNA.

Hint:

DNA is responsible for genetic storage, while RNA plays a crucial role in protein synthesis and gene expression.

Answer 1

Step 1: Define DNA and RNA. - DNA (Deoxyribonucleic Acid) is a double-stranded molecule that carries genetic information. It is found in the nucleus of eukaryotic cells. - RNA (Ribonucleic Acid) is a single-stranded molecule that plays a role in protein synthesis and gene expression. It can be found in the nucleus and cytoplasm.
Step 2: Compare their structure. - DNA contains deoxyribose sugar, whereas RNA contains ribose sugar. - DNA has thymine (T) as one of its nitrogenous bases, while RNA has uracil (U) instead of thymine.
Step 3: Functions. - DNA stores and transmits genetic information. - RNA helps in protein synthesis and gene regulation.
Final Answer: The main difference between DNA and RNA lies in their structure and function. DNA is double-stranded, contains deoxyribose, and uses thymine, while RNA is single-stranded, contains ribose, and uses uracil.
