Define gene expression
Provide an example of gene expression: A section of a gene is used a template and copied in the form of mRNA. The mRNA is used for in the process to match the right protein during the translation stage of protein-synthesis. This allows genes to code and express proteins...
Hey there,
When chemical bonds are formed, heat is generally released into the surroundings (e.g water) Reaction enthalpy (delta H) is negative for an exothermic reaction because the products have lower enthalpy than the reactants. This is because energy is released during bond formation. Since...
