Of the three types of point mutations the most harmful are insertions and deletions. They result in what is known as a frameshift mutation. When a nucleotide base is either inserted or deleted it disrupts the amino acids coded for from the site of the mutation on to the end of the gene.
Your body absorbs two types of nutrients: macronutrients and micronutrients. Macronutrients (carbohydrates, proteins and fats) are your bodyâs direct fuel or energy sources, whereas micronutrients (vitamins, minerals, etc.) indirectly influence available energy by serving as catalysts to release the macros.
Macronutrients. Macronutrients are nutrients that your body requires in large amounts, and they make up the bulk of your diet. The three types of macronutrients are carbohydrates, fats and proteins. Carbohydrates -- sugars and starches -- break down into glucose, a simple sugar that your cells use as a source of energy.
