Summary Introduction

Introduction: Mechanism of expression of genes is regulated by various types of gene products. These genes can be switched on or off during the course of gene expression. Some genes express continuously, while some express only at the time of need of their expression.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer: Genes that are expressed at all time constantly are called constitutive genes. Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer:

Constitutive genes are those genes which express at constant levels at all time. Products of such genes regulate processes associated with biochemical activities of cells.

Option d. is given as “constitutive”.

Constitutive genes are special genes that are expressed at constant levels at every time for effective regulation of gene expression process. Hence, the correct answer is option d.

Reasons for incorrect answer:

Option a. is given as, “inducible”.

Inducible genes are genes whose activity is controlled by the external factors. These genes are not expressed all the times in the cell. Hence, option a. is incorrect.

Option b. is given as, “repressible”.

Repressible genes are genes whose activity is affected at the time of higher concentration of products. High product concentration represses these genes to maintain constant level of products in the cell. These genes are not expressed at all time at constant levels in the cell. Hence, option b. is incorrect.

Option c. is given as, “positive”.

No positive genes are associated with the gene regulation process. Hence, option c. is incorrect.

Option e. is given as, “negative”.

No negative genes are associated with the gene regulation and expression mechanisms. Hence, option e. is incorrect.

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

Conclusion

Constitutive genes express continuously at constant levels in the cell and perform a vital role in the regulation of gene expression.

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
