Answer:

A segment of DNA that carries the instructions for one polypeptide chain.

Explanation:

The DNA is the genetic material of almost all the living organisms but few exceptions are present in case of virus where RNA is present as genetic material.

The phenotype and genotype of the organisms is determined by the gene. Gene is the functional segment of the DNA that codes for the specific polypeptide chain and determines the different morphological characters of the organisms.

Thus, the correct answer is option (a).

Lostsunrise [7]

Answer:

The correct answer is option b. gonadotropin-releasing hormone.

The GnRH or the gonadotropin-releasing hormone is a releasing hormone that releases from the neurons of the hypothalamus. This releasing hormone is responsible for the secretion of the luteinizing hormone and follicle-stimulating hormone.

Thus, the correct answer is option B. gonadotropin-releasing hormone.
