What hormone released by the highlighted structures inhibits the secretion of FSH only?

soldi70 [24.7K]

Inhibin inhibits the secretion of FSH only.

<h3>What is the role of inhibin?</h3>

Inhibin is a protein mainly produced by the gonads.
In men it is produced by the Sertoli cells and it is produced by the granulose cells in women.
It negatively regulates the secretion of Follicle Stimulating hormone (FSH) from the pituitary gland.
FSH itself induces the production of inhibin for negative feedback.
Pituitary is a pea shaped endocrine gland present at the base of the brain. It is the major endocrine gland and controls growth, development and functions of other endocrine glands.
Hormone activin has opposite effect to inhibin. It enhances FSH biosynthesis and secretion.

What is a gene? Can someone tell me what is Euchromatin? Is Euchromatin also called a Gene? What's the difference between these

julsineya [31]

Answer:

In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.

Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.

The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)

3. What differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over fr

kramer

Answer:

I would expect to see a greater variety of traits observed. Simplistically, I would expect to see people with blue eyes and brown hair, blonde hair or red hair. Whereas in a population where chromosomes do not cross over, I would expect to see traits that are more frequently associated with each other. For example, I would expect to see a greater proportion of blue eyed people to be blonde because the gene for hair colour is more frequently associated with the gene for eye colour.
