b. Which of the following statements is not true? O Microarrays are used to determine gene expression of multiple genes through analyzing mRNA's currently present in an individual's cells. O Recombinant DNA combines DNA from multiple sources usually requiring the use of reverse transcriptase. O Biotechnology is any technology based in biology or a biological system. O DNA cloning typically uses vectors, usually bacteria, to replicate DNA molecules producing a population of cells all containing the cloned DNA of interest. O A paleontologist has recovered a bit of tissue from the 400-year-old preserved skin of an extinct dodo (a bird). To compare a specific region of the DNA from the sample with DNA from living birds, PCR would be most useful biotechnology technique to increase or amplify the amount of dodo DNA available for testing.

Alternative RNA splicing in eukaryotes can produce many different polypeptides from a single mRNA sequence by interpreting differing mRNA segments as introns or exons and splicing
them accordingly.
O
DNA methylation can reduce or halt DNA transcription as DNA is negatively charged and the added methyl is negatively charged causing the methylated DNA to supercoil becoming
inaccessible to RNA polymerase.
O Some operons such as the lac operon can be controlled through both positive and negative gene regulation.
O Eukaryotic gene regulation may involve modifying access to genes, transcriptional controls, mRNA modifications, translational controls, and post-translation protein degradation.
