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.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
