Select the incorrect statement.
a. rna synthesis proceeds in the 5' to 3' direction.
b. rho-independent termination involves a gc rich region followed by a short uracil sequence to release the newly transcripted rna.
c. in rho-dependent termination, an omega factor is responsible for displacing the core enzyme from the dna template.
d. there are two main mechanisms of termination in bacteria.

- In Rho-dependent termination, an omega factor is responsible for displacing the core enzyme from the DNA template.

Explanation:

Rho factor is the factor responsible for the termination at places in the genome where the use of an intrinsic terminator is not possible. Omega factor is not responsible for displacing the core enzyme from the DNA template.

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.
