Nucleic acids function to create, encode, and store biological information in cells, and serve to transmit and express that information inside and outside the nucleus.
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.

Answer:
Oral contraceptives inhibit the secretion of gonadotropins by inhibiting the secretion of GnRH through a negative feedback mechanism.
Explanation:
Most oral contraceptive pills have combined dosages of estrogen and progesterone or one of these hormones. The estrogen and progesterone are involved in negative feedback inhibition of gonadotropin-releasing hormone (GnRH). Presence of small dosages of estrogen and progesterone inhibit the secretion of GnRH and thereby, prevents the secretion of gonadotropins (LH and FSH).
FSH (Follicle-Stimulating Hormone) is required for maturation of follicles while LH (Luteinizing Hormone) is required for ovulation of mature follicle.
Hence, hormonal contraceptives prevent conception by preventing follicle development and ovulation due to the absence of gonadotropins (FSH and LH).
