a segment of DNA has an original code of ACA. this segment was mutated to AAA. after the mutation occured, the lrotien that was coded for was no longer able to maintain its tertiary structure. explain why.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
