Which of the following is NOT true?

Terminal transferase or telomerase refers to a ribonucleoprotein that supplements a telomere repeat sequence to the 3 prime terminals of telomeres. A telomere is present at each terminal of the chromosomes found in the majority of eukaryotes. It helps in safeguarding the terminals of the chromosomes from destruction or from getting combined with the adjacent chromosomes.

Telomerase has its own RNA molecule and works as a reverse transcriptase enzyme. Generally, telomerase is found active in gametes, in stem cells, and in the majority of cancer cells, however, it is generally present in low concentration or is absent in the majority of somatic cells. Thus, the decrease in the ends of the chromosomes suggests that the production of telomerase is taking place at low levels.

In vertebrates, hormone production by the endocrine system is often controlled, either directly or indirectly, by the nervous sy

den301095 [7]

Answer:

If the question was actually pointing these (thyrotropin-releasing hormone TRH gonadotropin-releasing hormone GnRH antidiuretic hormone ADH thyroid-stimulating hormone (thyrotropin) TSH prolactin PRL follicle-stimulating hormone FSH luteinizing hormone LH) as the phrases, then the answer will be

•Thyrotropin-releasing hormone TRH describes ANTERIOR PITUITARY

•Gonadotropin-releasing hormone GnRH describes the HYPOTHALAMUS

•Antidiuretic hormone ADH describes the POSTERIOR PITUITARY

•Thyroid-stimulating hormone (thyrotropin) TSH describes the ANTERIOR PITUITARY

•Prolactin PRL describes the ANTERIOR PITUITARY

•Follicle-stimulating hormone FSH describes the ANTERIOR PITUITARY

•Luteinizing hormone LH describes the ANTERIOR PITUITARY

Explanation:

but if the phrases were to be this

1. Releases oxytocin

2. Synthesizes and releases PRL

3. Synthesizes and releases TSH

4. Synthesizes some hormones that are released into blood vessels bound for another gland

5. Regulated by hormones released into portal blood vessels

6. Is an extension of the Hypothalmus

7. Synthesizes oxytocin and ADH

8. Integrates nervous and endocrine systems

(...as found from another source),

the answers will be

1. Posterior Pituitary

2. Anterior Pituitary

3. Anterior Pituitary

4. Posterior Pituitary

5. Posterior Pituitary

6. Posterior pituitary

7. Posterior pituitary

8. Hypothalamus

....respectively.
