The antiparallel arrangement within DNA molecules refers to Select one:

mylen [45]

Answer:

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.

igor_vitrenko [27]

<h3><u>Answer;</u></h3>

D. Sodium Ions

<h3><u>Explanation;</u></h3>

Ions play important and variety of roles in cellular activities.
The composition of the cell interior is markedly different from the outside environment of the cell.
The dominant positive ion within the cell is potassium with a concentration that is more than 10-fold higher than that of sodium.
Outside the cell the major positive ion reverses with sodium as the dominant positive ion.
