Transcription and Translation Notes for IB Diploma Year 1 DNA is a huge information database that carries the complete set of instructions for making all the proteins a cell will ever need! Although there are only four different bases in DNA (A‚ C‚ G and T)‚ the order in which the bases occur determines the information to make a protein‚ just like the 26 letters of the alphabet combine to form words and sentences: Compare: RAT - TAR - ART - same 3 letters; completely different meanings.

each chromosome exists as two genetically identical chromatids attached to their centromere. Each chromosome appears as two chromatids attached to a centromere. In the first meiotic division chromosomes align in homologous pairs. Points of contact form between members of the same homologous pair. The points of contact or crossing over between members of a homologous pair are the chiasmata. 3. The homologous pairs move to the equator of the cell. Equal lengths of the chromatids of the same homologous

TOPIC 6‚ 11‚ & OPTION H: HUMAN HEALTH AND PHYSIOLOGY Digestive System Includes all the structures that are concerned with bringing food into the body to provide for the needs of the body’s cells. Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical

31.1 NOTES Before the 1800s‚ people thought that illnesses were caused by spirits. Around 1850‚ however‚ that all changed with the developments that were made by three scientists. Their work provided evidence that disease is caused by germs. • In 1857‚ Louis Pasteur came up with germ theory‚ which states that diseases are caused be small‚ physical particles and not spirits. These disease-causing particles are called pathogens. Around 1865‚ Joseph Lister found that cleaning his surgical tools
