Answer:
The backbone of the helix attached to the sugar, in between the Deoxyribose sugar
Explanation:
Two strands of DNA form a twisted ladder-like structure by wrapping around one another. The deoxyribose and phosphate units that make up the backbone of each strand alternate in direction. Adenine (A), cytosine (C), guanine (G), and thymine (G) are the four bases that are joined to each sugar (T).
Answer:
Option C. Cellular transport that does not require cellular energy, is the correct statement.
Explanation:
Movement of molecules requires energy for transportation from one place to another.
Passive transport is a type of transport in which molecules moves from one place to another without the use of energy. In passive transport, one molecule pulls another molecule and as a result the molecule moves from one region to another.

Redwoods sequoia sempervirens
<span>DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.</span>
