Question

Chapter 28, Problem 1U

Summary Introduction

Introduction:

“Biomarkers” are the chemical remains of the ancient organisms embedded in rocks. They are useful for the analysis and composition of the remains of the organisms prevent in the evolutionary history of the organism.

Expert Solution & Answer

Answer to Problem 1U

Correct answer:

“Biomarkers” are the chemical substances found in the ancient remains of the organisms which are helpful in the analysis of the remains of the organisms in the evolutionary history. Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

Biomarkers help in the study of the imprint of the remains of the organisms present in the rocks. They help in the deciphering of the chemical structure and composition of the remnants of the organisms. They are present like an imprint on the rocks and are embedded inside them in a specific pattern.

Option b. is given as “A hydrocarbon found in an ancient rock layer”.

As, “biomarkers are the chemical substances present in the ancient layer of the rocks and helps in determining the structure of the ancient remains of the organisms” is the right answer.

Hence, the option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “A microfossil found in a meteorite”. The meteorite consists of the rocky mineral material from the outer space world in the universe. So, it is the wrong answer.

Option c. is given as “An area that is high in carbon-12 concentration in a rock layer”. The radioactive dating of carbon-12 is done in the ancient layer of the rocks for analyzing the age of the fossil records. So, it is a wrong answer.

Option d. is given as “A newly discovered formation of stromatolites”. The stromatolites are the ancient fossil records of the cyanobacteria in the ancient rocks. So, it is a wrong answer.

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

Conclusion

Biomarkers are the ancient imprint of the primitive organisms in the rock layers. They help in the deciphering of the structure and composition of the fossils.

When beta-lactamase was isolated from Staphylcoccus aureus and treated with a phosphorylating agent, only the active site, serine was phosphorylated. Additionally, the serine was found to constitute 0.35% (by weight) of this beta-lactamase enzyme. Using this, calculate the molecular weight of this enzyme and estimate the number of amino acids present in the polypeptide.
