The anatomy of the intrinsic conduction system causes contraction of the ventricles to begin at the apex and move superiorly. why is this important? view available hint(s)a. because the av bundle is the only electrical connection between the atria and the ventriclesb. so the atria can finish contracting before the ventricles contractc. so blood is forced upward, toward the semilunar valvesd. because the purkinje fibers conduct action potentials away from the heart apex

Transposon can cause mutations in genes at or near the site of transposon insertion. it is possible for these elements to transpose away from their original site, causing a reversion of the mutant phenotype. in some cases, however, even more severe phenotypes appear when these elements excise from this site, due to events at or near the mutant allele. what might be happening to the transposon or the nearby gene to create more severe mutations?
