Question

practice 1 match each vocabulary word with its definition. write the letter that corresponds to the correct definition in each blank. 1. gel electrophoresis 2. genome 3. stem cells 4. transgenic organism 5. dna fingerprint 6. plasmid 7. recombinant dna 8. human genome project 9. cloning a. a unique pattern created from dna segments that can be used to identify an individual or to identify family relationships b. a laboratory technique that runs electrical current through a gel to separate dna fragments by their size c. all of an organisms hereditary information d. dna that is formed by joining a short piece of dna from one organism to the dna of another organism e. a process of producing genetically identical copies of genes, tissues, or an entire organism f. an international effort that successfully sequenced human dna g. a circular piece of dna found in bacterial cells h. undifferentiated cells that have the ability to become different types of specialized cells i. an organism that contains genes from a different species

Explanation:

1. Gel electrophoresis is a lab - technique for separating DNA fragments by size using an electrical current through a gel, so it matches B.
2. The genome is all of an organism's hereditary information, so it matches C.
3. Stem cells are undifferentiated cells with the ability to become different types of specialized cells, so it matches H.
4. A transgenic organism contains genes from a different species, so it matches I.
5. A DNA fingerprint is a unique pattern from DNA segments for identification, so it matches A.
6. A plasmid is a circular piece of DNA in bacterial cells, so it matches G.
7. Recombinant DNA is formed by joining DNA from different organisms, so it matches D.
8. The Human Genome Project was an international effort to sequence human DNA, so it matches F.
9. Cloning is the process of producing genetically identical copies, so it matches E.
