<span>In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted to photons (energy).</span>
Answer:
Muscles are involved in the digestive system, immune system, and excretory system.
Answer:
carbon capture
Explanation:
There is a piece of machinery which takes in the air and filters out the carbon dioxide. carbon dioxide is then pumped into the ground and reacts with rock to form a solid compound
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.
