Answer:
A
Explanation:
You can see in the image I attached that it does resemble the shape of a twisted ladder.
The shape of a DNA molecule resembles a twisted ladder, a shape specifically termed a double helix. The two sides of the 'backbone' of the DNA are made of alternating sugar and phosphate molecules, while the 'rungs' are formed by pairs of nitrogen bases.
The shape of a DNA molecule is best described as 'like a twisted ladder'. This specific shape is called a double helix. The two sides of the ladder are made of alternating sugar and phosphate molecules, which form the 'backbone' of the DNA. The rungs of the DNA ladder are formed by pairs of four types of nitrogen bases. These bases pair in a specific way: Adenine (A) with Thymine (T), and Cytosine (C) with Guanine (G). The 'twisting' of the ladder is a key feature of the double helix structure, and this allows the large molecule to fit inside the tiny nucleus of a cell.

One component of the cell theory is A cell is the basic unit of structure and function of all organisms. Thus, option "D" is correct.
The cell contains genetic material in the form of DNA which is passed from the parent cell to the daughter cells after cell division.
All cells are similar in chemical composition as well as in metabolic activities.
All the physiological and biochemical functions usually take place inside the cell.
The activity of the cell depends upon the cell organelles and other cellular parts.
Thus, option "D" is correct.
