What kind of substance facilitates the hydrogen bonding of nucleotides into a new dna molecule?
son4ous [18]
The hydrogen bonding of nucleotides into a new DNA molecule is facilitated by enzymes. Hydrogen bonding is the electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom, such as oxygen or nitrogen. The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pairs forms two hydrogen bonds while the C-G pair forms three. The enzymes called DNA polymerases join the nucleotides by way of phosphodiester bonds.

DNA ___________ is important because it ensures that when a cell divides, the two resulting cells have the same genetic code. Pl
slega [8]

Answer: Replication

Explanation: When the cell is preparing to divide it will <u>replicate</u> its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)

explain how a carrier protein can facilitate the diffusion of glucose or other substances into the cell.
Sveta_85 [38]

Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.

How carrier protein facilitate the diffusion?

When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.

Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.

Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.
