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 solution that has the same osmotic concentration as a cells cytoplasms

leva [86]

Answer:

Isotonic

Explanation:

A solution that has same concentration os solutes inside and outside is called isotonic solution.As no concentration gradient is developed to induce the diffusion of large amount of water across the cell membrane rather water molecules freely diffuse in and outside the cell.So there is no gain and loss of water by the cell due to which the cell neither shrinks not swell
