Chapter 18, Problem 1U

A genetic map provides

a. the sequence of the DNA in a genome.

b. the relative position of genes on chromosomes.

c. the location of sites of restriction enzyme cleavage in a known sequence of DNA.

d. the banding pattern of a chromosome.

Summary Introduction

Introduction:

A map that is produced at the level of DNA sequence requires the entire sequence of genome. This thing was impossible once technologically. But, fundamentally there are only two types of maps, physical maps and genetic maps.

Answer to Problem 1U

Correct answer:

A genetic map provides the relative position of genes on chromosomes. Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

Genetic maps are also known as linkage maps. This method is used to identify the distance between the genes and the locus of a gene. This map is very important, because it helps in locating the traits on a chromosome.

Option b. is given as “the relative position of genes on chromosome”.

As, “genetic map provides the relative position of genes on chromosomes”, it is the right answer.

Hence, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “the sequence of the DNA in a genome”.

The sequence of the DNA in a genome can be provided by genome sequencing. So, it is a wrong answer.

Option c. is given as “the location of sites of restriction enzyme cleavage in a known sequence of DNA”.

Restriction maps provide the location of site of cleavage by restriction enzyme. So, it is a wrong answer.

Option d. is given as “the banding pattern of a chromosome”.

Chromosome maps are studied by cytologists to provide the banding patterns of chromosome. So, it is a wrong answer.

Hence, options a., c. and d. are incorrect.

Conclusion

Genetic maps also called as “linkage maps” are constructed on the basis of frequency obtained from recombination. It provides relative position of a gene on chromosome.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
