A teacher modeled part of a DNA molecule using two of these coiled springs. Which part of the DNA was the teacher most likely modeling?

The part of DNA that the teacher was modelling would be the backbone of DNA.

Explanation:

The DNA is made of double helical structure which is twisted. In the structure of DNA two strands are coiled among each other.

The DNA consists of the nitrogenous bases, phosphate groups and deoxy-ribose sugar.

The backbone of DNA is made up of sugar( alternating )and phosphate group.The nitrogenous bases such as adenine, cytosine ,guanine and thymine are joined to the deoxy-ribose sugar.

This backbone part was part that the teacher was making as a model by using two coiled springs.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
