Answer: Options A, B, C and D are correct.

Explanation: They can trigger the activity of histone acetyltransferases.

These RNAs functions by binding to histone-modifying complexes, to DNA binding proteins (including transcription factors), and even to RNA polymerase II.

They can silence genes by promoting the formation of euchromatin by arranging hetero- or euchromatic regions into close proximity may stabilize these domains or it may control the spreading of post-translational modifications (PTMs) to nearest chromatin.

They are actively involved in X chromosome inactivation.

They can regulate the translation and stability of mRNAs.

In Eukaryotic cells RNA transcription is a closely regulated process. Transcription of a lncRNA may regulate the transcription of nearby mRNA genes, either positively (maintaining active chromatin structure) or negatively (for example, colliding polymerases). In these cases, the RNA product may have no importance at all, or it could have an additional function.

I’m stage 2 of photosynthesis NADP becomes NADPH why?
nignag [31]
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion  is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure.
