ad-work [718]
Photosynthesis: 12 H2O + 6 CO2 -> 6 O2 + C6H12O6 + 6 H2O 

12 water molecules and 6 carbon dioxide molecules are the reactants. 6 oxygen molecules, 1 glucose molecule, and 6 water molecules are the products. 

<span><span>Light dependent</span> reaction happens at the thylakoid membrane, made up of lipid bilayers, which is conveniently located in the chloroplast -> Light-independent reaction (the Calvin-Benson Cycle) happens in the stroma -> creation of glucose molecule.

A nucleosome forms hydrogen bonds with what part of the DNA?
zhenek [66]

Answer:

D) with the phosphodiester backbone and with bases via the minor groove

Explanation:

The double helix is ​​a fairly rigid and viscous molecule of immense length and a small diameter. In this molecule a major groove and a minor groove can be observed.

The major groove is deep and wide, the minor groove is shallow and narrow.

DNA-protein interactions are essential processes in cell life (activation or repression of transcription, DNA replication and repair).

Proteins bind to the inner part of the DNA grooves, through specific junctions: hydrogen bonds, and non-specific junctions: van der Waals interactions, and other general electrostatic interactions.

The proteins recognize donors and acceptors of hydrogen bonds, methyl groups (hydrophobic), the latter exclusive of the major groove; There are four possible patterns of recognition in the major groove, and only two in the minor groove (see figures).

Some proteins bind to DNA through the major groove, some others through the minor groove, and some need to bind to both, but the nucleosome form hydrogen bonds via the minor groove with the phophodiester backbone.
