c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.
Explanation:
A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>
I annexed an image of the DNA structure.
I hope you find this information useful and interesting! Good luck!
A nurse can
identify possible developmental dysplasia of the hip (DDH) during a newborn
assessment through asymmetry of the gluteal folds. Asymmetrical buttock creases can
suggest hip dysplasia in infants but an ultrasound or x-ray study will need to
be done to determine whether the hips are normal or not just like a hip click.
