To tell:
The reason why the scientists who work with recombinant DNA do not know all the long-term effects of their work.
Introduction:
The recombinant DNA technology involves the isolation of genetic materials (DNA) from donor organisms (human, plant, or microorganism) and the insertion of them into recipient organisms after genetic manipulation. This technology is used to introduce genetically modified organism (GMO). The main goals of this technology are as follows: (i) elimination of undesirable

- What is the function of DNA polymerase? a. It degrades DNA in cells. b. It adds RNA nucleotides to a new strand. c. It coils DNA around histones to form chromosomes. d. It adds DNA nucleotides to a replicating strand. e. None of these.arrow_forwardCloning Genes Is a Multistep Process Which enzyme is responsible for covalently linking DNA strands together? a. DNA polymerase b. DNA ligase c. EcoRl d. restriction enzymes e. RNA polymerasearrow_forwardWhat impact has recombinant DNA technology had on genetics and society?arrow_forward
- Why Are There So Many DNA Polymerases?arrow_forwardOnce the strands have been replicated, the enzyme DNA polymerase I “cleans up” by removing the primers. Why must the primers be removed? Finally, the enzyme DNA ligase finishes up. What does DNA ligase do?arrow_forwardBy seeing the picture, how are Recombinant DNA formed? What is the difference between genetic modification and selective breeding?arrow_forward
- After one round of PCR, one molecule of DNA consisting of two complementary strands yields how many molecules of DNA for a total of how many strands?arrow_forwardHow many copies of a target DNA molecule are made after 30 cycles of PCR?arrow_forwardWhat do you mean by DNA Repair and Recombination?arrow_forward
- Why do some journals require the authors of articles describing DNA libraries to make those libraries available to other researchers?arrow_forwardIf you eat DNA all the time, why aren’t you harmed by it? What implication does this have on the commercial properties of DNA in your hair conditioner, nutritional supplements, skin cream, or genetically modified plants and animals?arrow_forwardAssuming you started with only one copy of a DNA sequence, how many copies should be present after 15 cycles of PCR?arrow_forward
