Study Notes
DNA and RNA
- All living organisms contain both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid)
- Focus on location, structure, and function of DNA and RNA
Protein Synthesis
- Protein synthesis is vital for life
- Proteins are formed by both DNA and RNA
Cellular Structure
- Cytoplasm: The base substance in cells where organelles are suspended; allows metabolic reactions
- Ribosomes: Small, round organelles, often attached to the endoplasmic reticulum or free-floating; sites of protein synthesis; found inside other organelles like chloroplasts and mitochondria, consisting of RNA and protein
-
Nucleus: Controls all cellular activities
- Nuclear membrane: Encloses the nucleus with pores for substance passage
- Nucleoplasm: Jelly-like fluid within the nucleus
- Nucleolus: Dark body within the nucleoplasm; produces ribosomes
- Chromatin network: Found in nucleoplasm; DNA forming chromosomes containing the genetic code of an organism
