DNA Structure and Function

Deoxyribonucleic Acid: a macromolecule that is responsible for storing and passing on genetic information.

The twisted ladder shape of a DNA molecule.

The scientists who discovered the structure and function of DNA based on Rosalind Franklin’s Xray diffraction photograph.

The monomers of DNA polymers that consist of a phosphate-sugar backbone and a single nitrogenous base.

Nucleotides pair up to form the rungs of a ladder, and the phosphate-sugar backbone acts like the sides of a ladder.

There are 4 possible Nitrogenous Bases in a DNA nucleotide: Guanine, Adenine, Cytosine and Thymine.

In DNA, Adenine always pairs with Thymine A-T (Like Apples-Trees), while Cytosine always pairs with Guanine C-G (Like Cars-Garage).

The weak connection that holds together matching nitrogenous bases.

The 4 nitrogenous bases, A, T, C, G, are arranged in patterns that become the instructions for building all parts of living things.

The physical attributes of any living thing that come from the genetic code.
