Which statement best describes restriction enzymes?
They randomly cut DNA molecules to generate numerous fragments. |
They are necessary for the polymerase chain reaction (PCR) to occur. |
They are important for cloning applications because they can be used to cut DNA at specific nucleotide sequences. |
They can cut only circular plasmid DNA. |

Question 2 Select the statement below that BEST describes the synthesis of cDNA. mRNA is used as a template strand to guide synthesis specific sequences of DNA are localized and quantified within a genome numerous DNA copies are made of a specific segment of DNA restriction enzymes are used to generate sticky ends on the gene of interest as well as the plasmid vector

Restriction enzymes recognize specific DNA sequences and cut each strand of DNA at specific locations at the target sequence. The result of digesting a particular genome with a particular restriction enzyme is a collection of restriction fragments of defined length and composition. These can be used to generate restriction maps or create pieces with sticky ends. These sticky ends can be used to attach to other fragments that have sticky ends caused by cutting with a different...
15- Which option BEST describes sticky ends by restriction enzymes B. Sticky ends A. Sticky ends are DNA fragments that carry a higher charge than normal after they have been cleaved are DNA fragments cleaved by a restriction enzyme so that one strand is longer than the other C. Sticky ends are DNA fragments cleaved by a restriction enzyme so that both strands are the same length. D. Sticky ends are DNA fragments that attract a carbohydrate molecule to one...
Which of the following is not a use of restriction enzymes? A. Bacteria produce them to cut up foreign viral DNA B. Making recombinant DNA C. Cutting a vector when cloning a gene D. Replicating DNA during PCR
14. Restriction endonucleases are a. enzymes that restrict DNA synthesis b. enzymes that cut DNA in specific sequences c. nuclear proteins that are involved in transcription d. components of the ribosomes involved in protein synthesis 15. The first step in southern blotting is a. converting DNA into RNA b. cutting high molecular weight DNA into smaller pieces c. converting RNA into DNA d. radioactively labeling the DNA so it can be detected after the procedure is complete 16. The major...
Which of the following makes restriction enzymes useful for DNA fingerprinting and RFLP analysis? a. they typically attach and ligate DNA fragments together b. they cause DNA to be translated into the plasmid c. they cause DNA to be transcribed into the plasmid d. they can only function when within the cytoplasm of a cell e. none of the others are true
