Answer:

The correct answer is -To a ladder.

Explanation:

Most commonly DNA molecule is considered and compared to a twisted ladder as the structure of DNA can be compared to a ladder. It makes the side of the ladder by an arrangement of alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder.

Nitrogenous bases that are purine and pyrimidine make up the 'rungs' or steps of the ladder and also bind with hydrogen bonds with one other in the rug as two bases make a single rug, and are attached to the backbone where the deoxyribose (sugar) molecules are located.

Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.

Characteristics in which protists exhibit varies from one species to the other.

For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term  known as phagocytosis) therefore making them to be heterotrophic in nature.

In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.
