You have isolated a transposable element from the human genome and have determined its DNA sequence.How would you use this sequence to determine thecopy number of the element in the human genome ifyou just had a computer with an Internet connection?
CRISPR-Cas9 was first developed as a molecular tool in 2012; during the next few years, its use in molecular biology exploded, as scientists around the world began applying it to many different research problems, and hundreds of research papers describing its application were published. Explain why CRISPR-Cas is such a powerful tool in molecular genetics.

- If you were offered the chance to have the genome of your newborn sequenced at a cost of 1,000, would you do so?arrow_forwardIn 1995, Hamilton Smith, Craig Venter and co-workers published the first complete genome sequence of a self-sustaining organism, that of the bacterium Haemophilus influenzae. Analysis of the genome sequence revealed that the organism does not have a gene that could encode a telomerase enzyme. What is the potential evolutionary consequence of this? Explain your answer.arrow_forwardYou have isolated a transposable element from the human genome and have determined its DNA sequence. How would you use this sequence to determine the copy number of the element in the human genome if you just had a computer with an Internet connection? (Hint: see Chapter 14.)arrow_forward
- What is a BLAST search? a. A mechanism for aligning consensus regions during wholegenome sequencing b. A search for similar gene sequences from other species c. A method of screening a DNA library d. A method for identifying ORFsarrow_forwardA molecular biologist wants to isolate a gene from a scorpion that encodes the deadly toxin found in its stinger, with the ultimate purpose of transferring this gene to bacteria and producing the toxin for use as a commercial pesticide. Isolating the gene requires a DNA library. Should the molecular biologist create a genomic library or a cDNA library? Explain your reasoning.arrow_forwardWhat is the role of streptomycin in CRISPR experiment? What biochemical changes (DNA, protein) occurred in those cells in which CRISPR worked?arrow_forward
- What is Sanger sequencing? Why do we use ddNTP? How to read a DNA sequence gel? c. What is a cDNA seq (RNA seq)? d. What is the main difference between a genomic and a transcriptome study?arrow_forwardThe genome of what free living organism was first fully sequenced, and when?arrow_forwardYou are performing an experiment using CRISPR-cas9 to genetically modify the LacZ gene of a culture of E. coli. After you run the experiment, you decide to use gel electrophoresis to genotype the different bacterial cultures to determine if the gene editing was successful. How could your electrophoresis results confirm that the PCR was successful? And how could your electrophoresis results confirm that you successfully extracted genomic DNA from your bacterial samples?arrow_forward
- "Whole-Genome Sequencing Is Widely Used for Sequencing and Assembling Entire Genomes". Explain this ?arrow_forwardIf you knew the mRNA sequence for the human insulin gene could you know what size cDNA fragment you would find on your DNA gel when you ran it against a size standard (a “molecular ruler”)? Would you continue with your insulin cloning experiment, if the DNA from your PCR was very different in size from that predicted by the insulin mRNA? Why or why not? Primers can sometimes bind and target the wrong gene, especially if the primers are allowed to bind to the DNA strands at a low temperature. PCR also preferentially amplify short segments of DNA. Would it be important to actually run the cDNA after the PCR on a DNA gel in order to check for a PCR product of the predicted size for the insulin gene? Why or why not?arrow_forwardDNA sequencing technology has been around since the late 1970s. Why didsequencing whole genomes present a challenge?arrow_forward
