Which genetic code might be found in a strand of rna
1)aagggt
2)acatga
3)ccaugg
4)gtcuac

The correct answer is- 3)CCAUGG.

The genetic code can be described as set of instructions that are present in RNA or DNA in the form of nucleotide sequences (having codons, a sequence of three nucleotide depicting particular amino acid).

The nucleotides that are present in RNA are- Adenine (A), Uracil( U), Cytosine( C), and Guanine (G).

Thymine, T (which is present in DNA) is absent in RNA. Instead of Thymine, Uracil (U) is present in RNA.

Thus, option 3) is the right answer.

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.
