Scientists look at thousands of mutagenized flies, one at a time, under a microscope. They are looking for flies that don't look like they have developed normally. They find a remarkable fly with an extra thorax and a complete extra set of wings. This is an example of: A crazy waste of time A forward genetic screen A reverse genetic screen

5) 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?
Fill in the following with the correct words about cloning (the first blank will be the first word and the second blank will be the second word. There are two types of cloning, the first is when scientists change the cellular function this is called cloning and can help with creating insulin and vaccines to name a few. The other type is when DNA is extracted from a somatic cell and is used to replace DNA in an egg, this is called cloning. O gene, organism O organism, gene O specific, general O micro, macro
Do all of them True/False 31) The process by which an electrical charge is used to introduce DNA into a cell to produce a transgenic organism is called electroporation.Answer: 32) Reproductive cloning is used to produce large amounts of mammalian proteins from transgenic agricultural animals such as cattle.Answer: 33) In gene addition, homologous recombination is used to remove the original gene and replace it with the cloned gene.Answer: 34) All stem cells have the potential to differentiateAnswer: 35) A bone marrow transplant involves the transfer of multipotent stem cellsAnswer: 36) The fact that in mammalian systems multiple genes may compensate for the loss of a gene is called gene redundancy.Answer:
Place the steps in the correct order from start to finish. Do not overlap steps.

What Are Clones? Cloning is a general term used for whole organisms and DNA sequences. Define what we mean when we say we have a clone.
Which of the following best describes the process of DNA sequencing? a. DNA is separated on a gel, and the different bands are labeled with fluorescent nucleotides and scanned with a laser. b. 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. DNA is broken down into its constituent nucleotides, and the nucleotides are then run on a gel and purified with a laser.
Figure 17.7 You are working in a molecular biology lab and, unbeknownst to you, your lab partner left the foreign genomic DNA that you are planning to clone on the lab bench overnight instead of storing it in the freezer. As a result, it was degraded by nucleases, but still used in the experiment. The plasmid, on the other hand, is fine. What results would you expect from your molecular cloning experiment? There will be no colonies on the bacterial plate. There will be blue colonies only. There will be blue and white colonies. The will be white colonies only.
Cloning Genes Is a Multistep Process In cloning human DNA, why is it necessary to insert the DNA into a vector such as a bacterial plasmid?
Cloning Genes Is a Multistep Process Which enzyme is responsible for covalently linking DNA strands together? a. DNA polymerase b. DNA ligase c. EcoRl d. restriction enzymes e. RNA polymerase
A gene from the bacteria Bacillus thuringiensis has been inserted into the genome of select corn plants. These plants, known as Bt-corn, are capable of producing a toxin that is harmless to humans and other mammals but toxic for the European corn borer, a common pest of corn. What type of genetic technology does the production of Bt-corn represent? cloning O DNA fingerprinting gene therapy O genetic engineering https://student.masteryconnect.com/%23 V4:2 96
Which of the following statements is TRUE about reverse genetics? OReverse genetics analysis starts with mutants with altered phenotypes and identifies the genetic causes of the mutant phenotypes. Reverse genetics can be performed by random mutagenesis but not targeted mutagenesis. Reverse genetics analysis starts with a known DNA sequence, mRNA, or protein. Reverse genetics analysis relies on controlled crosses between mutants with distinct phenotypes.
