Restriction enzymes are produced by bacteria as a defense mechanism against phages. The enzymes act like scissors, cutting up the DNA of the phage and thereby inactivating it.

Scientists can force bacteria to keep them. all plasmids that are used to deliver DNA contain genes for antibiotic resistance. Once bacteria have been treated with a plasmid, scientists grow them in the presence of antibiotic. Only those cells that contain the plasmid will survive, grow, and reproduce.]]> 2019-04-09 16:19:39 UTC https://padlet.com/savannah_lawson1/040919/wish/350014493 Describe savannah_lawson1 https://padlet.com/savannah_lawson1/040919/wish/350014578 How genetic engineering can improve human health.

Biotechnology is implemented in multiple fields from medicine to industrial biosciences to agriculture. scientists have already provided substantial benefits to humans through genetic engineering like the treatment of certain diseases, addressing environmental issues, and the production of food and energy.]]> 2019-04-09 16:19:46 UTC https://padlet.com/savannah_lawson1/040919/wish/350014578 Contrast savannah_lawson1 https://padlet.com/savannah_lawson1/040919/wish/350014784 one major difference between selective breeding and genetic engineering.

Selective breeding is the traditional method for improving crops and livestock, such as increasing disease resistance or milk yield. 

Genetic engineering is a faster way, which transplants genes for a desired characteristic into an organism.]]> 2019-04-09 16:20:00 UTC https://padlet.com/savannah_lawson1/040919/wish/350014784
