Study Notes
Proteins
- Proteins are made up of 20 amino acids
- These amino acids link together to form long chains
- Functions include: defence proteins, muscle growth, hormones (e.g., insulin regulates blood sugar)
Enzymes
- Enzymes are proteins that are crucial for metabolic processes
- Each metabolic step requires a specific enzyme
- The absence of an enzyme can alter characteristics (e.g., missing enzymes can cause metabolic disorders)
DNA
- DNA stores genetic information and acts as a blueprint for building proteins
- It is a double helix structure
- Complementary base pairing: Adenine (A) with Thymine (T), Guanine (G) with Cytosine (C)
RNA
- Similar to DNA, but with Uracil (U) in place of Thymine
- Acts as a temporary copy of DNA (mRNA)
- mRNA carries genetic instructions to ribosomes where proteins are synthesized
- mRNA has the precise order of amino acids that need to be assembled into a protein
