The antiparallel arrangement within dna molecules refers to select one:
a. each base bonding at the 1' position of the sugar.
b. a purine always bonding to a pyrimidine.
c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.
d. an original parent dna strand and one newly synthesized dna strand comprising a new dna molecule.

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 two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction allowing for the base pairs to complement one another, making it a more stable structure. When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.

I annexed an image of the DNA structure.

I hope you find this information useful and interesting! Good luck!

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.

the answer is 1. photosynthesis. glad to
