Explanation / Answer
13. restriction enzymes , these cut DNA at specific 4-8 bp sequences and leave blunt end or sticky end fragments.
14. plasmids . these are small, circular double stranded DNA molecule. DNA fragments can be inserted into plasmid vector to create recombinant plasmid.
15. an example of transgenic tomato . this type of tomate is created using genetic engineering with its genes modified.
16. reproductive cloning consists of animal which is genetically identical to the donor animal via somatic cell transfer. recombinant DNA are used to create genome in which genetic material are brought from multiple sources.
