Ever wondered how your body repairs cuts or grows new muscle? It all comes down to cell division - and there are two main types you need to know about.
Mitosis creates identical copies of cells. Your somatic cells (basically every cell except reproductive ones) use mitosis to replace damaged tissue and help you grow. Think of it as photocopying - you get exact duplicates with the same 23 pairs of chromosomes.
Meiosis is completely different and only happens in reproductive cells. This process creates four genetically unique gametes (sperm or eggs) with just 23 single chromosomes. It's like shuffling a deck of cards - each result is different.
Stem cells are your body's repair kit. Embryonic stem cells are pluripotent, meaning they can become any type of cell in your body. Tissue stem cells are more limited but still crucial - for example, blood stem cells in your bone marrow constantly produce new red blood cells and immune cells to keep you healthy.
Quick Tip: Remember that mitosis = identical copies, meiosis = genetic variety!

Stem cell research isn't just academic - it's already helping people recover from injuries and diseases. Scientists use stem cells for corneal repair and skin regeneration, plus they're brilliant for testing new drugs safely.
However, embryonic stem cells create ethical dilemmas because obtaining them requires destroying embryos. This sparks debates about whether the potential medical benefits justify the ethical concerns.
Cancer happens when normal cell division goes completely wrong. Cancer cells ignore the usual "stop dividing" signals and keep multiplying uncontrollably. This creates tumours - masses of abnormal cells that can break away and spread throughout your body, forming secondary tumours.
Understanding how normal cell division works helps scientists develop better cancer treatments. When cells lose control of their division process, the results can be devastating.
Key Point: Cancer is essentially cell division that's lost all its normal controls and regulations.

DNA is like your body's instruction manual, made up of four bases (A, T, G, C) arranged in specific sequences that form the genetic code. Before any cell can divide, it must copy all this information perfectly.
DNA replication is a precise process involving DNA polymerase, the enzyme that builds new DNA strands. However, it can only work in one direction, creating a "leading strand" that's copied continuously and a "lagging strand" copied in fragments. Primers act like starting points for this copying process.
PCR (Polymerase Chain Reaction) is a laboratory technique that amplifies tiny amounts of DNA. It's used in crime scene investigations, paternity tests, and diagnosing genetic disorders. The process involves heating DNA to separate strands, cooling to let primers attach, then heating again for replication.
This technology has revolutionised forensic science and medical diagnosis. A single hair or drop of blood can now provide enough DNA for analysis.
Remember: DNA polymerase always needs primers to get started - it can't begin copying from scratch.

Your cells don't use every gene all the time - gene expression controls which genes are "switched on" to make proteins when needed. This involves two main processes: transcription and translation.
RNA differs from DNA in key ways: it's single-stranded, contains ribose sugar instead of deoxyribose, and uses uracil (U) instead of thymine (T). There are three types: mRNA carries genetic messages, tRNA brings amino acids during protein building, and rRNA forms part of ribosomes.
During transcription, RNA polymerase copies DNA to create a primary transcript. RNA splicing then removes non-coding regions (introns) and keeps coding regions (exons) to form mature mRNA.
Translation happens at ribosomes, where mRNA codons are matched with tRNA anticodons to build proteins. Each three-base codon specifies which amino acid to add next, creating a precise sequence.
Top Tip: Think of mRNA as a recipe copied from the DNA cookbook, and ribosomes as the kitchen where proteins are made.

Here's something amazing: alternative RNA splicing means one gene can produce multiple different proteins depending on which exons are kept and which are removed. It's like having one recipe that can make different dishes depending on which ingredients you include.
Polypeptides form when amino acids link together through peptide bonds. These chains then fold into specific 3D shapes held together by hydrogen bonds and other interactions. The shape determines the protein's function - get the shape wrong, and the protein won't work.
Your phenotype (how you actually look and function) results from both the proteins produced by gene expression and environmental factors. This explains why identical twins can have slight differences despite having the same DNA.
The incredible variety of protein shapes allows them to perform countless different functions in your body, from enzymes that speed up reactions to structural proteins that give your cells shape.
Cool Fact: Your body can make thousands of different proteins from just about 20,000 genes thanks to alternative splicing!

Mutations are changes in DNA that can dramatically affect protein production. Single gene mutations involve alterations to individual nucleotides and come in three main types.
Substitution mutations can be missense (changing one amino acid), nonsense (creating premature stop signals), or silent (no effect). Insertion or deletion mutations often cause frame shifts, changing every amino acid after the mutation point - these usually have severe effects.
Splice site mutations affect how introns and exons are processed, potentially keeping introns or losing exons in the final mRNA.
Chromosome structure mutations involve larger changes: deletions remove chromosome sections, duplications add extra copies, inversions flip sections around, and translocations move sections to different chromosomes. These substantial changes are often lethal.
Important: Frame shift mutations are particularly dangerous because they affect every amino acid downstream from the mutation.

A genome contains an organism's complete genetic information - both protein-coding genes and non-coding DNA sequences. Genomic sequencing can now determine the exact order of nucleotide bases in entire genomes.
Bioinformatics uses computer analysis to compare sequence data and identify genes by looking for similarities to known sequences. This computational approach is essential because genomes contain billions of base pairs.
Personalised medicine uses individual genome sequences to select the most effective drugs and dosages for each patient. Pharmacogenetics specifically focuses on how genetic variations affect drug responses.
Genomic analysis can also predict disease susceptibility, allowing for preventive measures or early interventions. This represents a major shift from one-size-fits-all medicine to treatments tailored to individual genetic profiles.
Future Impact: Your personal genome sequence could become as important as your blood type for medical treatment.

Metabolic pathways are sequences of enzyme-controlled reactions that keep your cells functioning. Anabolic pathways build large molecules from small ones (requiring energy), while catabolic pathways break down large molecules (releasing energy).
Enzyme-substrate interactions follow the induced fit model: the active site changes shape when the substrate binds, improving the fit. Products have low affinity for the active site, so they leave easily.
Competitive inhibitors bind directly to the active site, blocking substrate access. You can overcome this by increasing substrate concentration. Non-competitive inhibitors bind elsewhere but change the active site shape - no amount of extra substrate can reverse this.
Feedback inhibition provides automatic control: when the end product reaches critical levels, it inhibits an earlier enzyme in the pathway, preventing overproduction. It's like a thermostat controlling temperature.
Key Insight: Metabolic pathways have built-in control systems that prevent waste and maintain balance.

Cellular respiration converts glucose into ATP - your cells' energy currency. This involves three main stages working together like a well-coordinated factory.
Glycolysis occurs in the cytoplasm, breaking glucose into pyruvate and producing some ATP plus NADH. The pyruvate then enters mitochondria for further processing.
The citric acid cycle (in the mitochondrial matrix) processes pyruvate through acetyl coenzyme A, generating more NADH and some ATP. However, most ATP comes from the final stage.
The electron transport chain (in the inner mitochondrial membrane) uses NADH to pump hydrogen ions across the membrane. When these ions flow back through ATP synthase, they drive ATP production. Oxygen acts as the final electron acceptor, combining with hydrogen to form water.
Energy Flow: Think of it as glucose → NADH → hydrogen ion gradient → ATP production.

Your muscles have two distinct fibre types designed for different activities. Slow-twitch fibres excel at endurance activities like long-distance running or cycling because they rely on aerobic respiration and resist fatigue.
These fibres pack loads of mitochondria, have excellent blood supply, and high myoglobin concentrations for oxygen storage. They primarily burn fats as fuel, which provides sustained energy.
Fast-twitch fibres generate power quickly but tire rapidly. They're perfect for sprinting or weightlifting but depend mainly on glycolysis for ATP. They have fewer mitochondria and store glycogen as their primary fuel.
During intense exercise when oxygen runs short, pyruvate converts to lactate, causing muscle fatigue. The oxygen debt must be repaid after exercise to convert lactate back to glucose in the liver, regenerating the NAD needed for continued glycolysis.
Training Tip: Different sports require different muscle fibre types - understanding this helps explain why sprinters and marathon runners have such different training approaches.
