A laser is used to fluorescently label the nucleotides present within the DNA, the DNA is run on a gel, and then the DNA is broken into fragments. c. Nucleotides are scanned with a laser and incorporated into the DNA that has been separated on a gel, and then the DNA is amplified with PCR. d. Fragments of DNA are produced in a reaction that labels them with any of four different fluorescent dyes, and the fragments then are run on a gel and scanned with a laser. e.

- Choose the correct statements from the list below. There may be more than one correct statement. A) If you start with 2 DNA templates, after four rounds of PCR you'll have 32 copies B) PCR is useful in making millions or billions of copies of a gene so that it is present in a quantity large enough to study C) quantitative PCR is very similar to PCR, but fluorescent probes are added so that we can measure how much PCR product exists by examining how much the reaction fluoresces D) In real-time reverse transcriptase PCR, the RNA is used as a template to make a cDNA copy (through reverse transcriptase)arrow_forwardSuppose you have been directed to find new enzymes to use in the breakdown of wood in order to process biofuel (switchgrass, for example). Suppose you wanted to use fungal or bacterial DNA from the environment in order to do so. DNA can be unwound from the double stranded double helix into single strands, amplified, separated on gels by size, stained with dyes. It can be mutated by a variety of means. It can be sequenced. Describe one or more of the ways that you might manipulate DNA towards the stated goal. Relate the technology you plan to utilize to the structure of DNA. (You can break this into multiple posts, as multiple procedures might be used).arrow_forward5) Below is an image that shows both reproductive and therapeutic cloning. Use this image to answer compare and contrast therapeutic and reproductive cloning. Are they used for similar means…etc. Once you have done that answer the question below. a) There are two types of therapeutic cloning. What are they and how are they different?arrow_forward
