Chapter 18, Problem 4A
Summary Introduction
Introduction:
Genome assembly is simply the sequencing of genome produced after fragmentation of chromosome and then those fragments are sequenced and resulting sequences have been set back together. Genome sequencing is the process of determining the sequence of organism’s genome.

You are studying celiacs disease and have identified a
potential gene for the disease using linkage analysis.
You decide to test your hypothesis by making
transgenic mice that carry a nonsense mutation in the
candidate gene you have identified to see if they
develop a phenotype similar to that found in Celiacs
disease
What sort or experimental approach are you using
when you test your gene in your mouse model?
a. Reverse genetic
b. Quantitative genetic
C. Forward genetic
D.Expression analysis
E. None of the above
The goal of most gene therapies is to insert a healthy copy of a gene into the genome. Besides CRISPR, techniques for integrating DNA into the genome do not target that DNA to a particular genomic location and thus different cells end up with the DNA sequence in different positions.
A. It has been shown that where the healthy gene integrates is heavily influenced by chromatin. Why?
B. The same gene integrated into different locations in the genome will be expressed differently. Why?
C. Over time the expression of an integrated gene will change, usually decreasing. Describe how you think the cell downregulates expression of an integrated gene.
a. What type of nucleic acid and from what species would the scientist use to begin
construction of her genomic DNA library?
b. From what tissue would she isolate this nucleic acid?
c. What type of reagent would the scientist use to cut the genome into appropriately sized
fragments?
d. What size nucleic acid fragments would one aim to prepare for the library construction
so as to to avoid having to screen an overwhelming number of clones?
e. Into what vector would the scientist ligate her genomic DNA fragments?
f. What organism would the scientist use to propagate the clones of her genomic DNA
library?
g. From the information given in the problem determine what probe could be used to
screen the scientist's library to find her clone of interest ?

- The following diagram outlines how the process of cloning a sheep was accomplished. Cloning is the process of creating a genetically identical copy of another individual. With Dolly, the first cloned mammal, an egg cell was removed from a donor (B) and the nucleus was removed from the egg cell. Then cells from a sheep's mammary gland were removed from a second donor (A). The nucleus of one of the cells from the mammary gland was fused with the enucleated egg cell using an electrical pulse. The fused cell underwent cell division and at the blastocyst stage was implanted into a surrogate mother sheep. The fused cell is cultured and is implanted as a multi-celled embryo. During the step where the fused cell begins dividing normally, the cells of the future clone undergo Select one: a. fertilization b. meiosis c. mitosis d. gene splicingarrow_forwardA paper hypothesizes that white flowers are unable to produce anthocyanins (purple pigments) because they lack a functional “A” protein. However, it is also possible that an unknown gene is responsible for the lack of anthocyanins. Now that they have isolated DNA sequences of the “A” allele, design an experiment to use these DNA sequences to distinguish between these two hypotheses.arrow_forwardDolly is the first mammal to have been successfully cloned from an adult cell Which of the following statement/s is/are most relevant to the birth of Dolly?
