A newborn's DNA Is screened for hearing loss. The codon sequence used as the check for normal hearing is TAT AGA GGA GGC MAG TOG TAA. However, the newborn's codon sequence comes back as TAT AGA GGA GAC AAG TCGTM What can be concluded regarding the infant's codon sequence?

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.
