Which of the following is not true of a single nucleotide polymorphism?

a. It is usually caused by a translocation mutation.

b. It is usually caused by a nucleotide substitution mutation.

c. It may change the phenotype of an organism.

d. It is inherited from parent to offspring.

Expert Solution & Answer

Summary Introduction

Introduction:

Single nucleotide polymorphisms (SNPs) are a type of mutation in which one nucleotide at a particular position on deoxyribonucleic acid (DNA) is replaced by another nucleotide. SNPs are responsible for a number of genetic disorders in humans.

Answer to Problem 1MC

Correct answer:

SNPs cannot be caused by a translocation mutation.

Explanation of Solution

Justification/Explanation for the correct answer:

SNPs are caused by the replacement of one nucleotide at a particular position on the DNA by another nucleotide. Translocation refers to the rearrangement of segments of chromosomes, meaning that a particular segment of a chromosome breaks off from its location and reattaches at a new location. Option (a) is given that SNPs are usually caused by translocation mutations is a false statement. Hence, option (a) is correct.

Explanation for the incorrect answer:

Option (b) is given that SNPs are caused by nucleotide substitution mutations is a false statement. SNPs are caused by the substitution or replacement of a particular nucleotide at a given position with a different nucleotide. So, it is an incorrect option.

Option (c) is given that SNPs may change the phenotype of an organism is a false statement. SNPs can be of two types: synonymous and nonsynonymous. In a synonymous SNP, the amino acid coded by the triplet is not changed and the same protein is made. In a nonsynonymous SNP, the amino acid encoded by the triplet changes and an altered protein is made. This altered protein would give a different phenotype to the affected individual. So, it is an incorrect option.

Option (d) is given that SNPs are inherited from parent to offspring is a false statement. SNPs are changes in the DNA. Any change in the DNA of the parent will be passed on to his/her offspring because DNA is the basis of inheritance. So, it is an incorrect option.

Hence, options (b), (c), and (d) are incorrect.

Conclusion

Therefore, it can be concluded that SNPs are substitutions of a single nucleotide at a particular position by another nucleotide. They are passed on from the parent to the offspring and may alter the phenotype of the individual.

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
