[QUOTE="hope, post: 2653627, member: 211900"] Polymerase chain reaction allows ________. Answer insertion of new DNA segments into a DNA molecule insertion of new RNA segments into a DNA molecule specific mutations to occur within a DNA molecule multiple copies of DNA to be made A scientist wants to insert a gene for vitamin A into a rice plant. The scientist would use ________. Answer a vector a restriction enzyme DNA ligase All of the choices are correct. Insulin and human growth hormone are two examples of products produced by ________. Answer transgenic plants "pharm" animals transgenic bacteria All of the choices are correct Which of the following is in correct order for the lac operon? Answer lactose binds to repressor – RNA polymerase binds to promotor – repressor binds to operator repressor binds to operator – RNA polymerase binds to promotor – lactose binds to repressor repressor binds to operator – lactose binds to repressor – RNA polymerase binds to promotor RNA polymerase binds to promotor – repressor binds to operator – lactose binds to repressor Mechanisms of gene expression in eukaryotes affect ________. Answer activation of the operon the speed of gene expression the length of time a gene is expressed both the speed and length of time of gene expression [/QUOTE]
