Chapter 6, Problem 1DYKB
Summary Introduction

Introduction:

The mammary glands are the specialized, paired structures located on the chest. These organs have the main function to secrete milk to feed the young ones. These organs are also present in males but in females, they are more developed. Progesterone is the hormone that helps in the development of breasts. Prolactin helps form milk and is secreted from the anterior pituitary.

Answer to Problem 1DYKB

The correct answer is option (b) they are modified apocrine glands.

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) is mammary glands are modified apocrine glands. These glands are found in both males and females but get activated only in females during pregnancy and lactation periods. Hence, this option is correct.

The explanation for the incorrect answers:

Option (a) is they release their secretion onto the hair follicle. Apocrine sweat glands secrete their secretions into the hair follicles. There are no hair follicles in mammary glands. Hence, this option is incorrect.

Option (c) is the product packaged in vesicles and released through exocytosis. In mammary glands, the secretion does not occur by exocytosis. Hence, this option is incorrect.

Option (d) is the product they secrete that acts as a lubricant and is waterproof. Ceruminous glands produce products that act as a lubricant and are waterproof. An example of such a product is ear wax. Hence, this option is incorrect.

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences  A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?
Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
