6th Grade Science PBL Unit 2 Task 2 6th Grade Science PBL Unit 2 Task 2 Questions ● When did genetic modification start? Genetic modification k0lpcaused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another w```as first accomplished by Herbert Boyer and Stanley Cohen in 1972. ● How has technology impacted genetic modification?“Traditional” genetic modification involves inserting the DNA of one species into another. Now they are tinkering with novel and, for the most part, untested, methods, intentionally changing the RNA of an entity to turn off “undesirable” traits. No longer do they have to…show more content…
In what way?in plants These methods of selective breeding can potentially positively influence world food production in these ways improved quality of seed grains, increased levels of proteins in forage crops. It is also beneficial by helping the plants to be more resilient to insects and disease. They are also making them to have a capacity to grow on lands that are not suitable for them to grow in which can be a benefit and that way you can get more food and a variety of different plants even if it is in a land which can’t suit them. This show that it helps people ● What is the purpose of selective breeding?The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated. ● What are the pros and cons to genetic engineering?Pros and Cons of Genetic Engineering. Manipulationof genes in natural organisms, such as plants, animals, and even humans, is considered genetic engineering. This is done using a variety of different techniques like molecular cloning. ● Does selective breeding help or hinder resistance against diseases in animals/organisms? In plants?
