Briefly discuss the current controversy about which complex organic molecules formed first: nucleic acids or proteins
Romashka-Z-Leto [24]

The controversy surrounding the nucleic acids and proteins, regarding which one of them was formed first is the most popular controversy in the biology world today. The nucleic acids stores and the genetic information. The proteins essential for all the life processes are encoded by the genes formed of the nucleic acids (DNA and RNA). But proteins (enzymes) are required for the formation of proteins from the genes. The inter-dependency of the nucleic acids and proteins on each other possesses a dilemma to the question 'which of them arrived first'.

The answer to this dilemma was answered when it was discovered that RNA was capable of not only carrying the genetic information, but also acting as catalyst to the chemical reaction. This finding supported the notion that the RNA evolved first serving the purpose of both the nucleic acids and emzymes.

- Thyroid gland : Produces thyroid hormones that regulate the body metabolism, play an important role in bone growth and development of the brain and nervous system in children!

- Parathyroid glands : Release parathyroid hormone which plays a role in regulating calcium levels in the blood and bone metabolism.

- Adrenal glande : Produce hormones that help the body control blood sugar, burn protein and fat, react to stressors, and regular blood pressure.

- Pineal body/gland : Secretes the melatonin hormone which may help regulate the wake-sleep cycle of the body.

- Reproductive glands : Main source of sex hormones for males and females.
