What is the letters of the complimentary base pairs to convert this DNA strand in to an RNA strand: GCTGCA

CGACGU

Explanation: Remember the base pairing rules: cytosine with guanine and adenine with uracil (in the absence of thymine, which mRNA does not have). To compliment the given strand, you'd have to choose the base that would pair with each individual nucleotide.

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.
