What would happen if the nucleotide sequence of a gene got mixed up?

If this gene codes for a protein, a change in the sequence of the gene would subsequently change the sequence of amino acids of the protein. This would most probably affect the function of the protein due to subsequent changes in the conformation (that is affected by the interactions between the among acids – and their functional groups)

69 is the correct math for the amino acids

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
