Chapter 21, Problem 1E
Summary Introduction

Introduction :

In endocrinology, the permissive effect can be defined as where one hormone can work in the presence of another hormone. Permissiveness is a type of biochemical phenomenon, in which the presence of one hormone is necessary to activate another hormone for its full effects on a target cell.

Answer to Problem 1E

Correct answer :

Correct answer is option (d) Both a and c.

Explanation of Solution

Explanation/justification for the correct answer :

Option (a) effect of thyroid hormone on growth. The thyroid is a steroid hormone and it can bring out changes in the expression of certain genes. The thyroid hormone can promote the transcription of the gene involved in the production of the growth hormone. So, the secretion of the growth hormone cannot be done in the absence of the thyroid hormone. In this case, the thyroid hormone poses permissiveness for the growth hormone.

Option (c) effect of sex hormone on the secretion of growth hormone. The sex hormone helps in modifying and the growth-promoting effects of the growth hormone. Hence, the sex hormone has a permissive effect on the functioning of the growth hormone.

Option (d) given as both a and c. As the thyroid hormone and the sex hormones both have a permissive effect on the growth hormone, the option (a) and (c) are true. Hence, option (d) is the correct answer.

Explanation for incorrect answer:

Option (b) is given as the effect of insulin on glucose uptake by cells. It is not able to stimulate the formation of receptors for the hormone, like a permissive hormone. Hence, it is the wrong answer.

Option (e) is given as all of the above. As the insulin is not a permissive hormone, option (b) is incorrect. Hence, it is the wrong answer.

Conclusion

Thus, effect of thyroid hormones on growth and the effect of sex hormones on secretion of growth hormone, is an example of permissive hormones.

In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?

There are many differences between DNA replication happening during mitosis in a Douglas fir tree growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence Repeat. Complete the following table that compares the two DNA replication events in terms of the primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value for the number of copies of the template DNA after one S phase in one cell and after the lab has completed the PCR reaction. Tree SSR Type your answer here: Primers Nucleotides Polymerase Target sequence Number of copies
