Question
Which of the following structures are responsible for the overall shape of a cell? A. Microvilli B. Cytoskeleton C. Cell junctions D. Organelles In the Polymerase Chain Reaction (PCR), the first step is: A. The double-stranded DNA molecule fuses to form one strand B. The Taq polymerase binds and starts to synthesize a new DNA strand C. The double-stranded DNA molecule separates by being denatured or "melted" D. The primers bind to the specific region you wish to study E. None of these choices are correct The ultimate goal of PCR is to: A. Make billions of copies of the region of DNA you wish to study B. Stabilize the region of DNA you wish to study since DNA is highly fragile C. To make an RNA strand from the DNA strand to study what proteins will ultimately be made D. Purify your DNA sample so that it will be "clean" enough to further study Biotechnology: A. Is the study of genes and the molecular details that regulate the flow of genetic information B. Understand how proteins and enzymes function in critical life processes C. Uses information gained from molecular biology to manipulate an organisms' DNA to help solve human problems D. The use of computers to probe specific biological functions of bacteria What is the purpose for removing Mg^2+ from your DNA sample? A. To help increase speed of enzymatic reactions B. Mg^2+ is a contaminant that may make your DNA sample impure C. To help decrease unspecified enzymatic reactions as Mg2+ acts as a cofactor D. If left in your sample, the Mg^2+ ions will bind to the DNA causing it to denature We discussed that 95% of DNA is noncoding. Noncoding DNA is also called: A. Exon B. Intron C. DNA Polymerase D. Helicase E. Ligase Humans have approximately how many genes? A. 30,000 - 50,000 B. 100,000 - 500,000 C. 500,000 - 1,000,000 D. 1,000,000 - 10,000,000 E. Over 10,000,000Explanation / Answer
