Summary Introduction

Introduction:

Recombinant DNA is defined as the joining of two different DNA from two different species and then the integrated DNA transformed into the host. This technology is termed as recombinant DNA technology and used in science, medicine and agriculture.

Expert Solution & Answer

Answer to Problem 1U

Correct answer:

A recombinant DNA molecule is constructed from DNA from different sources. Therefore, option (b) is correct.

Option (b) is given as “constructed from DNA from different sources”.

Explanation of Solution

Justify reason for the correct statement:

Recombinant DNA technology also known as genetic engineering is a technique that involves alteration of genotypes as well as phenotypes of organisms. This technology isolates DNA from donor organisms (human, plant, or microorganism) and inserts them into recipient organisms after genetic manipulation. Thus, the construction of DNA takes place from different sources. The important tools used for manipulation of genotype and phenotypes are nucleic acids, restriction enzymes, ligase, vectors, reverse transcriptase, and mutagens.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “produced through the process of crossing over that occurs in meiosis”.

The DNA that is formed after meiosis has undergone crossing over but the source of DNA (parent cell) is same while recombinant DNA is constructed by using DNA from different sources. Hence, it is a wrong answer.

Option (c) is given as “constructed from novel combinations of DNA from the same source”.

DNA from same source is not used in recombinant DNA technology. Hence, it is a wrong answer.

Option (d) is given as “produced through mitotic cell division”.

Mitotic cell division results in same kind of DNA which cannot be used in recombinant technique. Hence, it is a wrong answer.

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

Conclusion

Construction of recombinant DNA requires DNA from different sources.

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
