Textbook Question
Chapter 21, Problem 2PDQ
CONCEPT QUESTION Review the Chapter Concepts list on page 485. All of these pertain to how genomics, bioinformatics, and proteomics approaches have changed how scientists study genes and proteins. Write a short essay that explains how recombinant DNA techniques were used to identify and study genes compared to how modem genomic techniques have revolutionized the cloning and analysis of genes.

explain the ethical concerns for this biotechnology method (sanger sequencing)
Transcriptome analysis involves two separate methodologies: gene expression and RNA seq analyses. The 10 items below are a scrambled listing of the steps used in the two procedures. Identify the steps involved in RNA seq from the list below. Use the numbers in the list to refer to each step. Once the steps for RNA seq have been identified, write the steps in the order in which they are performed during the experiment.
(1) DNA sequencing
(2) Allow for hybridization and wash excess cRNA.
(3) Mix labeled cRNA with array chip.
(4) PCR amplification
(5) Measure fluorescence intensity to determine abundance of transcripts.
(6) Add labeled cRNA at each microarray location.
(7) Map cDNA sequences to the genome of the organism to determine identity and abundance of transcripts.
(8) mRNA isolation from cells
(9) Prepare fluorescently labeled cRNA probes
(10) cDNA synthesis
An unapproved form of gene therapy, known as enhancement gene therapy, can create considerable ethical dilemmas. Why?

Task A: Polymerase Chain Reaction Master Mix Your first task is to isolate and amplify the NRAS gene from cDNA extracted from differentsamples through PCR. You will need to run a total of 7 PCRs: 3 normal samples, 3 canceroussamples, and 1 negative control. To make things easier in the lab, when running multiplereactions, the components are prepared not individually, but as a master mix—all thecomponents for multiple reactions are prepared in bulk, except for the template DNA, which isadded separately once the master mix has been distributed into individual tubes. The table below lists the different components for PCR, the available stock concentrations of thesecomponents, and the needed working concentrations for the PCR itself.

Using your textbook as a resource, complete the following steps to assist you in completing this gene cloning project. 1. You have identified the specific gene that produces the protein product that you wish to mass produce. What is the first step you need to do in order to obtain a version of this human gene that be cloned into a bacterial cell? What special enzyme, obtained from a particular kind of virus, will you need to complete this first step? (Hint: Are there differences in genes between eukaryotes and prokaryotes?) 2.
