Which of the following is the term used to describe the process of synthesizing RNA from a DNA template strand?
Complementary strand of a DNA sequence.
Replication fork formation.
Transcription initiation.
Okazaki fragment synthesis.
The Correct Answer is C
Transcription initiation is the term used to describe the process of synthesizing RNA from a DNA template strand.
Choice A is incorrect because a complementary strand of a DNA sequence refers to the strand that is complementary to the original DNA strand.
Choice B is incorrect because replication fork formation refers to the process of separating the two strands of DNA during replication.
Choice D is incorrect because Okazaki fragment synthesis refers to the synthesis of short fragments of DNA on the lagging strand during replication.

Estrogen is a steroid hormone responsible for the development of female secondary sexual characteristics such as breast development, menstrual cycle, and widening of hips.
Choice A, Progesterone, is not the correct answer because it is required to maintain pregnancy and delivery.
Choice B, Testosterone, is not the correct answer because it is a hormone produced by the testes which control the development of male secondary sexual characteristics.
Choice D, FSH (Follicle Stimulating Hormone), is not the correct answer because it stimulates the growth of ovarian follicles in females and regulates spermatogenesis in males.
Correct Answer is A
Explanation
Hydrogen bonding is an interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons.
One atom of the pair (the donor), generally a fluorine, nitrogen, or oxygen atom, is covalently bonded to a hydrogen atom, whose electrons it shares unequally; its high electron affinity causes the hydrogen to take on a slight positive charge.
The other atom of the pair (the acceptor), also typically F, N, or O, has an unshared electron pair, which gives it a slight negative charge.
Mainly through electrostatic attraction, the donor atom effectively shares its hydrogen with the acceptor atom, forming a bond.
Choice B) The repulsion between the positive and negative charges of two molecules is incorrect because hydrogen bonding involves attraction, not repulsion.
Choice C) The attraction between two nonpolar molecules is incorrect because hydrogen bonding involves polar molecules.
Choice D) The attraction between two ionic molecules is incorrect because hydrogen bonding involves polar molecules and not ionic molecules.
