Chapter 11, Problem 38P

As explained in the text, the cause of many genetic diseases cannot yet be discerned by analyzing whole exome/genome sequences. But in some of these seemingly intractable cases, important clues can be obtained by looking at mRNAs or proteins, rather than at the DNA.

a. As you will see in more detail in later chapters, it is possible to use single-molecule methods to sequence cDNA copies of millions of mRNA molecules from any particular tissue cheaply. How could you sometimes use such information to find a disease gene? When would this information be noninformative?
b. A technique called Western blotting allows you to examine any protein for which you have an antibody; it is possible to see differences in size or amount of that protein. How could you sometimes use such information to find a disease gene? When would this information be noninformative?

This problem investigates issues encountered in sequencing the inserts in cDNA libraries.a. If you sequenced many clones individually, wouldn’tyou spend many of your resources inefficiently sequencing cDNAs for the same type of mRNA molecule over and over again? Explain. Does thisapparently inefficient process provide any useful information beyond the sequences of individual mRNAs?b. Suppose that you identified a clone with a cDNA insert that was 4 kb long. You could determine the entire sequence of the clone by shearing the DNA intosmall random fragments, cloning these fragments intoa vector to make a mini-shotgun library, and then sequencing hundreds of these clones to allow the computer to assemble the full sequence of the 4 kb–longinsert. However, this procedure would be inefficient.An alternative that requires many fewer sequencing reactions is called primer walking. This techniqueinvolves the synthesis of additional oligonucleotideprimers corresponding to cDNA sequences you…
You would like to add a nuclear localization sequence (NLS) of Lys-Lys-Lys-Arg-Lys to a protein that is usually found in the cytoplasm of a yeast cell. To accomplish this, you introduce the nucleotide sequence encoding the NLS into the gene that encodes the cytoplasmic protein of interest. a. What is the size of the nucleotide insert that will encode the NLS? Briefly explain. 5' 3' b. Below is a diagram of the gene encoding the cytoplasmic protein of interest in the yeast genome. If your goal is to put the NLS at the carboxyl (C) terminus of the protein, at which location (A-E) should the NLS be inserted? Briefly explain. A TATAA ATATT promoter +1 B ATG TAC D TAA ATT stop codon E 3' 5'
In order to target a specific region of genomic DNA with CRISPR, researchers must include a guide RNA containing a 20-basepair long spacer sequence that matches the DNA sequence at the target site. (i) How many possible guide RNA spacer sequences are there? (ii) One of the possible risks of genetic engineering methods is “off-target” editing, where a modification of the genome occurs in a part of the genome other than the target site. Imagine you design a 20-basepair guide RNA spacer sequence to target a specific portion of the Zebrafish genome, which is 1.7 billion nucleotides long. Assuming all nucleotides are equally common, estimate the probability that your spacer sequence occurs in at least one other position in the Zebrafish genome.
