Sometimes mutations (changes to dna) alter the protein that is made and sometimes it does not. explain how this is possible from what you know about the protein synthesis process.

when the chromosomes divide to create a new cell they miked get mixed up and the RNA will have to change it

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
