Question
Chapter 18.3, Problem 2LO
Summary Introduction
To explain: The reason why sequencing the human genome was a comparatively simple endeavor than sequencing the wheat genome.
Introduction: An organism’s complete DNA set, including all of its genes, is termed as a genome. The main aim of the genome project is to determine the organism’s whole genome sequence and annotate the genes that code for proteins and other essential genome-encoded features.

- Propose a method for isolating a DNA fragment that is adjacent in the genome to a previously isolated DNA fragment. Assume that you have access to a complete library of DNA fragments in a BAC vector but that the sequence of the genome under study has not yet been determined.arrow_forwardwhat is the whole-genome shotgun sequencing? Also briefly explain its strategy to assemble the genome sequence.arrow_forwardAssume 2x108 reads of 75 bps long are obtained from a next-generation sequencing experiment to sequence a human genome. Suppose the length of the human genome is 3x109 bps. What is the depth (i.e., coverage) of the sequencing?arrow_forward
- How did the private corporation Celera Genomics approach the sequencing of the human genome? What was the advantage of this approach?arrow_forwardIn the practical you have been analysing a human genomic library. You know from your calculations that only a small proportion of the human genome is represented, even when the entire class results are considered. Therefore, the chance of finding a particular single-copy gene in your library is very small. Outline a strategy for constructing a genomic DNA library more representative of the entire human genome. You will need to consider alternative vectors and the efficiency of transformation of the bacterial cells.arrow_forwardWhy is Sanger sequencing sometimes referred to as "dye-terminator" sequencing?arrow_forward
- Describe the process for shotgun sequencing of a genome. Practice aligning the two sets of sequenced fragments below, to determine the order of the fragments and the complete sequence.arrow_forwardDescribe the possible outcome of a PCR experiment in which (a) there is a single-stranded break in the target DNA sequence, which is present in only one copy in the starting sample, and (b) there is a doublestranded break in the target DNA sequence, which is present in only one copy in the starting sample.arrow_forwardThe temperature at which the primers and target DNA hybridize may be changed to influence the stringency of PCR amplification. What effect will changing the hybridization temperature have on the amplification? Let's say you have a certain yeast gene A and want to check whether it has a human equivalent. How might managing the hybridization's rigor benefit you?arrow_forward
- What are the main differences between whole genome sequencing and whole exome sequencing?arrow_forwardSuppose that a human genomic library is prepared by exhaustive digestion of human DNA with the EcoRI restriction enzyme. Fragments averaging about 4 kb in length would be generated. Is this procedure suitable for cloning large genes? Why or why not?arrow_forwardExplain the difference between sequencing by chain termination and sequencing by synthesis. Which one does dideoxy sequencing use? Which one does next generation sequencing use? Thank youarrow_forward
