Textbook Question

Chapter 8, Problem 1MCQ

A DNA molecule is placed in a test tube containing fluorescently tagged nucleotides. DNA replication is induced. After replication,

a. only one DNA molecule would have two fluorescent strands.

b. both strands of each DNA molecule would be half-fluorescent.

c. each DNA molecule would have one fluorescent strand.

cl. both DNA molecules would be completely fluorescent.

Expert Solution & Answer

Summary Introduction

Introduction:

DNA replication is a process of producing two identical copies of DNA from parental DNA. DNA replication is known as semicoservative, because each new copy will have one parental strand.

Answer to Problem 1MCQ

Correct answer:

Each DNA molecule would have one florescent strand. This statement explains correctly that DNA replication is a semi conservative process. Therefore, option c. is correct

Explanation of Solution

Reason for the correct statement:

DNA replication is a semi conservative process in which new replicas of DNA will have one parental strand. So, in this DNA molecule one strand will be normal and other strand will be florescent.

Option c. is given as “each DNA molecule would have one florescent strand”.

As, “DNA replication is a semi conservative process so whenever a new replica is formed it will always have one parental strand, so in this DNA molecule one strand will be normal and other strand will be florescent”, is the right answer.

Hence, option c. is correct.

Reasons for the incorrect statements:

Option a. is given as “only one DNA molecule would have two florescent strands”.

This is never possible in case of replication because if replication occurs then parental strand is shared within the replicas, so both florescent strands cannot stick together. So, it is a wrong answer.

Option b. is given as “both strands of each DNA molecule would be half florescent”.

This is the case of dispersive replication, but in case of DNA it only replicate through semicoservative way. So, it is a wrong answer.

Option d. is given as “both DNA molecules would be completely florescent”

This is the case of conservative replication, but in case of DNA it only replicate through semi-conservative way. So, it is a wrong answer.

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

Conclusion

DNA replicates through semi-conservative way in which new replica is formed and that new replica will always have one parental strand.
