Doing cardiovascular exercise is essential as doing strength training. Both have <em>different targets.</em> Strength training targets the <u>muscles of the body.</u> It promotes bone growth and makes you stronger. On the other hand, cardio exercise targets the <u>heart rate</u>. The more the heart pumps, the more oxygen the blood receives in the body.
Strength training gives you an<em> afterburn effect </em>that allows you to keep burning calories even after you workout, while cardio exercise allows you to burn more calories in a shorter span time–especially when you're doing <em>high-intensity exercise</em>.
Clearly, both strength training and cardio exercise are essential.
Genes go from DNA to (m)RNA via transcription. Then, RNA is converted to protein via translation. For eg, the insulin hormone is a peptide hormine (peptide is basically protein) which comes from insulin mRNA which was the result of transcription of insulin gene in beta islet cells of pancreas.
