Which of the following genetic markers is best used for plant DNA barcoding? a. rbcl gene O b. cytochrome-b gene C. Ribosomal RNA O d. cytochrome c oxidase i (coi) gene

If a researcher accidentally transformed the bacterial two hybrid plasmids ( pKT25-X and pUT18-Y) into a normal strain of E coli that produces adenylate cyclase, his/her experiment will: a. show a high lacZ activity in all tubes (control and experiment) because Proteins X and Y do not need to be interacting in order to activate lacZ gene prescription. b. not work because cells lack cAMP. c. need replicates in order to show true interaction between X and Y.

HindIII is a restriction endonuclease that recognizes a palindrome sequence. Predict which one is the HindIII recognition site: a. AAGGTT b. AAGCTT c. AGCCGA d. AGCGCA e. AGCAGC

Which of the following statements best describes the function of SDS in western blotting? Select one: A. It can solidify polyacrylamide gel. B. It allows the transfer of proteins from polyacrylamide gel to nitrocellulose membrane. C. It can form a colored product with proteins. D. It can linearize protein molecules. E.

1. Scientists were able to develop transgenic bacteria that can be used for mercury remediation.  This process involved combining genes for mercury resistance (so that the bacteria itself has protection) and mercury accumulation (thereby allowing the bacteria to sequester Hg for retrieval later on). They probably used the following techniques in creating the transgenic bacteria EXCEPT a. plasmids b. DNA ligase c. DNA polymerase d. restriction enzymes   2. Consider these two parents (Mom and Dad) and their son, Calvin.  (see pic attached). Which two members of this family would show the greatest difference in their DNA profile?

Defects in the excision  repair process may result in : A. Mutations B. Okazaki fragments C. Excess DNA polymerase activity D. Shortened telomeres

Which of the following statements is false? a. Plasmids can be exchanged between different species of bacteria. b. The blue circle represents a small chromosome. c. The blue circle is a plasmid that contains genes that confer resistance to specific antiobiotics. d. The blue circle represents a double-stranded molecule of DNA.
