A DNA 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.
d.	both DNA molecules would be completely fluorescent.

Expert Solution & Answer

Summary Introduction

Introduction:

DNA is a double-stranded nucleic acid that is responsible for the genetic inheritance. Each strand of DNA is a double helix composed of two antiparallel strands of nucleotides. The complementary nucleotides form hydrogen bonds with each other and hold DNA double helix together.

Answer to Problem 1MCQ

Correct answer:

A DNA is placed in a test tube containing fluorescently tagged nucleotides. DNA replication is induced. After replication, each DNA molecule will have one fluorescent strand. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

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

DNA is the genetic molecule and exhibits a double helix structure. According to Watson and Crick, DNA replication is semi-conservative, which suggests that during replication, one strand of DNA will be original and another will be a new strand. In the presence of fluorescent nucleotides after DNA replication, only the new strand will be fluorescent. Hence, option c. is correct.

Reason for incorrect answer:

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

During DNA replication one of the DNA strands acts as a template and a new strand is formed over it. Therefore, one DNA molecule will always be nonfluorescent if only one replication cycle happens. Hence, option a. is incorrect.

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

During replication, the new strand is formed based on the original strand. Hence one full strand acting as a template will be nonfluorescent, and the new strands will be fluorescent. Hence, option b. is incorrect.

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

Both DNA molecules will be completely fluorescent if multiple replication cycles happen. Still the original DNA strands will be nonfluorescent and will have new fluorescent strands. Hence, option d. is incorrect.

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

Conclusion

DNA replication is semiconservative, which means that during replication the original DNA strand will act as a template and new strand is formed over it. Thus, the correct option is c.

Students have asked these similar questions

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
