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.

Which of the following statements did Yamanaka rely on to produce induced pluripotent stem cells (IPSC)? [Note: This is higher level thinking. All statements on their own are correct and may be related to IPSC production but there is only one statement that played an essential role in the production of IPSC) O A. A proportion of embryonic stem cells can differentiate into adult stem cells. B. Only a small proportion of genes are expressed in each celI. C. Telomerase is active in pluripotent stem cells. D. All genes retain the potential to be expressed.

E. coli has five genes that code for enzymes that make tryptophan. These genes are regulated by a single promoter and transcribed as one long gene. The presence of tryptophan shut down the production of tryptophan by the cell by binding to the repressor. This changes the repressors shape allowing it to bind to DNA operator, blocking RNA polymerase and cutting off the production of tryptophan. a. Describe what woud happen to the operon if some of the cells had a mutation on the repressor, not allowing it to bind with tryptophan. The repressor is described as an allosteric protein. What does this mean? b. Does the tryptophan model demonstrate an inducible or repressible operon? What is your evidence? *
