Question
Chapter 18, Problem 28P
Summary Introduction
a.
To determine:
The portion of sgRNA that corresponds to crRNA and tracrRNA as per the figure given in the book.
Introduction:
A sgRNA (Single guide RNA) is made up of crRNA and tracrRNA (Trans activating RNA). In the CRISPR technique, both parts of the sgRNA are combined in one single molecule.
Summary Introduction
b.
To determine:
The reason due to which the fact that inside the bacterial genome, the CRISPR locus does not possess any PAM sites is crucial. Also, determine the way in which these PAM sites help in immunity of bacteria.
Introduction:
In the genome of the bacterium, the CRISPR locus does not contain PAM (Protospacer adjacent motif) sites. These are short DNA (Deoxyribose

- How many types of reactions can an enzyme perform?arrow_forwardYour goal is to produce black seeds resistant to mold. So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants. Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus.

- Using Punnett Squares Punnett squares are one good way to predict the outcome of genetic crosses. Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. The number of possible alleles from each parent determines the number of rows and columns in the Punnett square. Independent Assortment KEY QUESTION How do alleles segregate when more than one gene is involved? Mendel wondered if the segregation of one pair of alleles affects another pair. For example, does the gene that determines the shape of a seed affect the gene for seed color? This type of experiment is known as a two-factor, or dihybrid, cross because it involves two different genes. Single-gene crosses are monohybrid crosses.
