Match the following column given fluence with its induce phytochrome responses;

COLUMN A	COLUMN B
A) low-fluence responses (LFRs)	i) do not show Photoreversibility while Law of Reciprocity is followed
B)  high irradiance responses (HIRs)	ii) Shows the Photoreversibility and also the Law of Reciprocity is followed
C) Very low fluence response (VLFR)	iii) It will absorb red and blue light and responses is measuredly recepted by phytochrome A
	iv) In dark-grown: far red, blue, UV-A recepted by Photoreceptor phyA and cryptochrome
	v) ) It will absorb Red, far-red and responses is measurely recepted by phyB, phyD, phyE

Repressive complexes have been discovered that are composed of multiple repressing proteins bound to RNAs many kilobases in length that do not contain long open reading frames and are consequently called long noncoding RNAs or lncRNAs. Which of the following statements is correct regarding the regulation of these lncRNAs?

The edges of each base pair are exposed in the major and minor grooves, creating a pattern of hydrogen-bond donors and acceptors and of hydrophobic groups (allowing for Vander Waals interactions) that identifies the base pair. The edge of an C : G base pair displays the following chemical groups in the following order in the major groove:
