DNA is what kind of molecule?

• Amino Acid

• Carbohydrate

• Nucleic Acid

• Protein

This is the scientific term to describe a curve that goes around a central tube or cone shape in the form of a spiral 

• Cone

• Helix

• Hexagon

• Prism

In short DNA can be described as a

• Single helical chain

• Double helix

• two circular chains

These make up the "sides" of the DNA strands

• Hydrogen bonds and Nitrogenous bases

• Nitrogenous bases and Sugars

• Phosphates and sugars

• Sugars and hydrogen bonds

These makes up the rungs of the DNA ladder

• Hydrogen bonds and nitrogenous bases

• Phosphates and sugars

• Nitrogenous bases and sugars

• Sugars and hydrogen bonds

All of these are examples of nitrogenous bases found in DNA except

• Adenine

• Cytosine

• Guanine

• Uracil

In DNA, Adenine will always bond to

• Cytosine

• Guanine

• Thymine

• More than one is correct

In DNA, Guanine will always bond to

• Adenine

• Cytosine

• Thymine

• More than one is correct

This type of bond holds the nitrogenous bases together

• Amino bonds

• Hydrogen bonds

• Peptide bonds

• Lipid bonds
