The  central dogma  of molecular biology is centered upon the process of protein synthesis, in which the information from dna is transcribed and translated, resulting in multiple amino acids being joined to form a)lipidsb)proteinsc)carbohydratesd)nucleic acids

What is the role of dna ligase in the elongation of the lagging strand during dna replication?

Lactase is essential for digesting lactose in milk. this enzyme is specific for this sugar. why? molecules and active sites vary in size; only properly sized molecules can fit.there is a precise compatibility between the active site and the lactose molecule.specificity refers to the action of the enzyme, such as hydrolysis, and relatively few molecules can be hydrolyzed.reaction-specific enzymes assume a fit by folding around the most numerous substrate molecules.
