DNA: THE CODE OF LIFE notes

This section revises the parts of the cell that DNA and protein synthesis depend on: the nucleus, the cytoplasm and the ribosome. It then introduces the two kinds of nucleic acids, DNA and RNA…

This section covers where DNA is found in a cell, a brief history of how its structure was discovered, the structure of DNA and its nucleotides, how its bases pair, and the functions of DNA. DNA…

DNA replication is the process in which a DNA molecule makes an exact copy of itself. This section covers when and where it happens, how it takes place, and why it is important. DNA replication is…

DNA profiling, also called DNA fingerprinting, produces a pattern of bands from a person's DNA that is unique to that person. This section covers how to interpret a DNA profile and the uses of DNA…

This section covers RNA: where mRNA and tRNA are found, the structure of RNA and its nucleotides, how to draw stick diagrams of mRNA and tRNA, and the function of RNA in protein synthesis. RNA…

Every cell makes proteins, such as enzymes, hormones and the proteins that build new cell structures. The instructions for each protein are stored as a code in DNA. Making a protein happens in two…
