Human Genomehe building and operation of the human body. The message is written in an alphabet that uses only four letters: A, C, G, and T. Each of the letters represents one of the four bases which are the chemical building blocks of DNA: A— adenine, T— thymine, C — cytosine, and G — guanine. The nucleotides w

Gene Regulation and Expression a cell divides, the entire human genome, that is, all the DNA stored within the nucleus, must be copied. In Figure 2.1 the replication of DNA is demonstrated. The regulation of a cell’s function is controlled by altering gene expression. The steps in gene expression are (1) transcription of the gen

Tools of Recombinant DNA Technologyenzymes are a major tool of recombinant DNA technology. A restriction enzyme recognizes a specific nucleotide sequence, such as AGCT, and cuts DNA wherever that combination of “letters” occurs. These enzymes are isolated from bacteria and named with a three- or four-letter sequence followed by a rom

Infectious Diseaseses begins part 2, in which we will apply recombinant DNA technology to the study, diagnosis, and treatment of disease. For infectious diseases, the application of molecular medicine is both straightforward and dramatic. We can take any clinical sample and analyze it for the presence of foreign, nonh

Genetic Diseasesy limited in its ability to probe the complexity of the human genome. The famous genetic breeding experiments in viruses, bacteria, yeast, slime mold, and fruit flies taught us a great deal about genetics in general. However, applying classical genetics to human diseases was limited by our scant kno

Immune System and Blood Cellsifferent cell types. Our understanding of the details is incomplete, yet enough has already been seen to appreciate the wide range of the body’s repair and defense mechanisms. We know more about the biology of blood cells than we do about most other tissues in the body because of the ease with which
