Gene Technologies and Human ApplicationsSection 1 Section 1: The Human Genome Preview Bellringer Key Ideas Secrets of the Human Genome Applications of Human Genetics Ongoing Work Summary

Gene Technologies and Human ApplicationsSection 1 Bellringer Human Genes Have you ever wondered about your genes? If you could investigate any part of your own body’s DNA, what would you like to find out? Write down some of your questions.

Gene Technologies and Human ApplicationsSection 1 Key Ideas Why is the Human Genome Project so important? How do genomics and gene technologies affect our lives? What questions about the human genome remain to be studied?

Gene Technologies and Human ApplicationsSection 1 Secrets of the Human Genome Genomics is the study of entire genomes, especially by using technology to compare genes. The Human Genome Project (HGP) was an international cooperative effort to sequence the human genome. The sequencing of the human genome has advanced the study of human biology yet created new questions.

Gene Technologies and Human ApplicationsSection 1 Visual Concept: Genome

Gene Technologies and Human ApplicationsSection 1 Secrets of the Human Genome, continued Surprising Findings Humans have few genes. Most human DNA is noncoding. Many human genes are identical to those of other species. All humans are genetically close.

Gene Technologies and Human ApplicationsSection 1 Applications of Human Genetics Genomics and gene technologies have many applications in human healthcare and society. Diagnosing and Preventing Disease A microarray shows which genes are being actively transcribed in a sample from a cell. Genetic counseling informs people about the risk of genetic problems that could affect them or their offspring. Various vaccines are now produced through genetic engineering.

Gene Technologies and Human ApplicationsSection 1 Applications of Human Genetics, continued Treating Disease Some genetic disorders can be treated by supplying a genetically engineered protein. Another possible treatment is gene therapy, to insert a replacement gene into a person’s cells by using a genetically engineered virus.

Gene Technologies and Human ApplicationsSection 1 Genetically Engineered Medicine

Gene Technologies and Human ApplicationsSection 1 Applications of Human Genetics, continued Identifying Individuals DNA fingerprints are now used regularly to confirm the identity of criminals, family members, or dead bodies.

Gene Technologies and Human ApplicationsSection 1 DNA Fingerprint

Gene Technologies and Human ApplicationsSection 1 Ongoing Work Many important questions about the human genome remain to be investigated or decided. Such as: –How do our genes interact? –How unique are we? –Can genetics help us live longer? –How should we deal with ethical issues?

Gene Technologies and Human ApplicationsSection 1 Summary The sequencing of the human genome has advanced the study of human biology yet created new questions. Genomics and gene technologies have many applications in human healthcare and society Many important questions about the human genome remain to be investigated or decided.
