a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.
Thus, Deoxyribonucleic acid, or DNA, has a double helix-like structure. It is made up of two lengthy nucleotide strands that are spirally coiled around one another.
The complementary nitrogenous bases adenine (A) and thymine (T) and cytosine (C) and guanine (G) form hydrogen bonds that hold the two strands together.
This double helix structure is frequently compared to a spiral staircase or a twisted ladder.
Thus, a double helix best describes the structure of the sides of the DNA molecule. The correct option is A.

b. It is rigid.
c. It is alive.
d. It stretches.gy
The best answer is b - it is rigid.
The cell wall is defined as the rigid, outermost layer found in plants and also certain bacteria, algae and fungi. It is absent in animal cells.
The plant cell wall is made up cellulose which is a structural carbohydrate. The cell wall is rigid and thus offers structural support allowing plant such as trees to grow to great heights.
It also helps prevent water loss, helps protect against insects and pathogens and keeps the shape of the plant.
