Question

1. what is cloning? copies of an organism
2. how are bacteria used in genetic engineering?
3. how could gene therapy someday be used to treat gene
4. what is the human genome project?

Explanation:

1. Cloning is a biological process that creates genetically identical copies of an organism, cell, or genetic material.
2. Bacteria act as vectors/hosts: they take up recombinant DNA, replicate rapidly, and produce large quantities of desired proteins or modified DNA for genetic engineering applications.
3. Gene therapy could replace, repair, or supplement faulty disease-causing genes with functional ones, either by delivering healthy genes directly to target cells or editing the defective genes to restore normal function.
4. The Human Genome Project was an international scientific effort that mapped and sequenced the entire set of human DNA, identifying all human genes to advance understanding of human biology, disease, and genetics.

Answer:

1. Cloning is a biological process that produces genetically identical copies of an organism, cell, or genetic material.
2. Bacteria are used as vectors/hosts: they accept recombinant DNA, replicate quickly, and mass-produce desired proteins or modified genetic material.
3. Gene therapy could treat genetic disorders by replacing, repairing, or supplementing defective genes with functional versions to restore normal cellular function.
4. The Human Genome Project was an international research initiative that mapped and sequenced the complete human DNA set, identifying all human protein-coding genes to advance genetic and medical research.
