The structure of DNA consists of a long molecule that looks somewhat like a ladder that has been "twisted." The shape of the DNA molecule is referred to as: Select one: a. the twisted rope b. the double helix c. the Golgi apparatus d. the double rope

## Step 1<br />The problem is asking for the correct term that describes the shape of the DNA molecule. The DNA molecule is known for its unique structure, which resembles a twisted ladder. This structure is known as a double helix.<br /><br />## Step 2<br />The term "double helix" is used to describe the structure of DNA because it consists of two strands that are twisted around each other, resembling a ladder that has been twisted.<br /><br />## Step 3<br />The other options provided, such as "the twisted rope", "the Golgi apparatus", and "the double rope", do not accurately describe the structure of DNA. The Golgi apparatus is an organelle found in most eukaryotic cells, and it is not related to the structure of DNA.
