Textbook Question

Chapter 15, Problem 1U

The experiments with nutritional mutants in Neurospora by Beadle and Tatum provided evidence that

a. bread mold can be grown in a lab on minimal media.

b. X-rays can damage DNA.

c. cells need enzymes.

d. genes specify enzymes.

Expert Solution & Answer

Summary Introduction

Introduction:

To identify the working nature of genes, scientists from all over the world conducted various experiments. The results revealed by them include, the functions controlled by the genes and the enzymes specified by the genes.

Answer to Problem 1U

Correct answer:

The experiments with nutritional mutants in Neurospora by Beadle and Tatum provided evidence that genes specify enzymes. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

Beadle and Tatum showed that genes specify enzymes. In neurospora, each enzyme of the arginine pathway was encoded by a separate gene. The mutant species of neurospora were unable to synthesize arginine. Beadle and Tatum found that specific enzymes controlled by specific genes were absent in the mutant neurospora. They proposed the one gene-one enzyme hypothesis.

Option d. is given as "genes specify enzymes".

As, “the experiments with nutritional mutants in Neurospora by Beadle and Tatum provided evidence that genes specify enzymes”, it is the right answer.

Hence, the option d. is correct.

Reasons for the incorrect statements:

Option a. is given as “bread mold can be grown in a lab on minimal media”.

In the experiments conducted by Beadle and Tatum, bread mold was grown to determine the enzymes specific for the growth. So, it is a wrong answer.

Option b. is given as “X-rays can damage DNA”.

The experiments conducted by Beadle and Tatum to determine the limiting factors for specific enzymes and not to determine what X-rays do to the DNA. So, it is a wrong answer.

Option c. is given as “cells need enzymes”.

The experiments conducted by Beadle and Tatum were performed to determine the limiting factors, which control synthesis of enzymes responsible for specific functions. So, it is a wrong answer.

Hence, the options a., b., and c. are incorrect.

Conclusion

The experiments with nutritional mutants in Neurospora by Beadle and Tatum provided evidence that genes specify enzymes.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)
