9) (1 point) To carry out Polymerase Chain Reaction (or PCR), one must provide: a. Two short DNA primers, which together delineate the start and the end of the replicated double-stranded segment of DNA b. Two short DNA primers, which together delineate the start and end of the replicated single-stranded segment of DNA c. Two identical RNA primers, which together delineate the start and end of the replicated double-stranded segment of DNA d. None of the above 10) (1 point) If a synthetic biologist wishes to transcribe the coding sequences of two proteins into one transcript, he/she would have to: a. eliminate all ribosome binding sites (RBS) from the transcript b. use two promoters, two protein coding sequences, and exactly one terminator c. use a promoter, 2 RBSs, 2 protein coding sequences, and 1 transcription terminator d. None of the above 11) (1 point) The -10 and -35 sequences, which are part of a promoter, are situated: a. 10 and 35 bases, respectively, downstream of the transcription start site b. 10 and 35 bases, respectively, upstream of the transcription start site c. 10 and 35 bases, respectively, upstream of the ribosome binding site d. 10 and 35 bases, respectively, downstream of the ribosome binding site
