When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. ... This model for replication suggests that the two strands of the double helix separate during replication, and each strand serves as a template from which the new complementary strand is copied
A host cell is an animal or plant
A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.
Enzymes are biological catalysts – they speed up chemical reactions. Enzymes are required for most of the chemical reactions that occur in organisms . These reactions occur in the breakdown of chemical molecules, which we see in the digestive system . ... Enzymes are proteins that have a complex 3D-shape.
