Study Notes
Structure of DNA and RNA
- The primary difference in structure between DNA and RNA is the sugar component, with DNA containing deoxyribose and RNA containing ribose.
- DNA is primarily located in the nucleus of eukaryotic cells, and in the cytoplasm of prokaryotic cells.
Function of RNA
- RNA plays a crucial role in transcribing and translating genetic information from DNA into proteins.
- The main job of RNA is to act as a messenger, carrying genetic information from DNA to the ribosomes, where proteins are synthesized.
Structure of DNA
- DNA is double-stranded, with two complementary strands twisted together in a helical structure, held together by hydrogen bonds between nitrogen bases.
- The structure of DNA allows it to be replicated and transcribed efficiently.
Nitrogen Base Pairing
- Adenine (A) pairs with Thymine (T) in DNA, and Adenine (A) pairs with Uracil (U) in RNA.
- Thymine pairs with Adenine in DNA.
Similarities between DNA and RNA
- Both DNA and RNA are nucleic acids, composed of nucleotides, with sugar, phosphate, and nitrogen base components.
- Both DNA and RNA contain the nitrogen bases Adenine (A) and Guanine (G).
Test your knowledge on the structure and function of DNA and RNA, and distinguish their differences and similarities. Explore the importance of DNA and RNA in the human body. Additionally, challenge yourself with a word search to find hidden biology-related words.
