AP BIOLOGY CHAPTER 20 DNA TECHNOLOGY AND GENOMICS PAGE 375 Mapping and sequencing of human genome has been accomplished Via recombinant DNA ?. Genes from two different sources Genetic engineering?? manipulaton of genes? Biotechnology ?..manipulation to make useful products? Microbes to make wine and cheese, selective breeding of livestock DNA Cloning Making multiple identical copies of gene-sized DNA A gene inserted into a plasmid Bacteria reproduces?.recombinant plasmid is replicated Diagram pg 376 Potential uses ?.. Produce a protein product Ex. Gene for human growth hormone Produce many copies of gene So the gene nucleotide sequence can be determined Or give an organism a new metabolic ability?.pest Resistance?.

Chapter 20 DNA Technology and Genomics Overview: Understanding and Manipulating Genomes One of the great achievements of modern science has been the sequencing of the human genome, which was largely completed by 2003. Progress began with the development of techniques for making recombinant DNA, in which genes from two different sources?and often different species?are combined in vitro into the same molecule. The methods for making recombinant DNA are central to genetic engineering, the direct manipulation of genes for practical purposes. Applications include the introduction of a desired gene into the DNA of a host that will produce the desired protein.

The definition of Biology
Biology is the study of life. Alongside physics and chemistry, biology is one of the largest and most important branches of science. At the highest level, biology is broken down based on the type of organism being studied: zoology, the study of animals; botany, of plants; and microbiology, of microorganisms. Each field has contributed to mankind or the Earth’s well-being in numerous ways. Most prominently: botany, to agriculture; zoology, to livestock and protection of ecologies; and microbiology, to the study of disease and ecosystems in general.

Genetics Gene Glossary

Holandric ? Genes found on the Y- Chromosome Teratogens ? agents of nature that cause abnormalities in the foetus Polytene chromosomes ? chromosomes that successively replicate without any cell division making ?chunk?. Oncogene ? gene that under high temperature and mutation turn a normal cell in to a cancer cell, such as a tumor cell. Histones ? a protein that shortens the long DNA molecule so that all the DNA molecules can fit inside the nucleus. Totipotency- the ability of a cell to reactivate all the genes in a genome. Chromosomal puffs ? indicate a region where DNA replication is taking place. Supercoiling ? is the coiling of DNA. It reduces the space and allows for a lot more DNA to be packaged.
