Genetics- Structure of DNA

Molecules composed of building blocks called nucleotides, which are linked together in a chain

• Nucleic acids
• Proteins 
• Lipids 
• Carbohydrates

Adenine, thymine, cytosine, guanine and uracil are examples of nitrogenous bases that may be found in nucleotides.

• Nitrogenous base
• Protein
• Carbohydrates
• Lipids

The concept that in DNA every adenine (A) binds to a thymine (T), and every cytosine (C) binds to a guanine (G). 

• Complementary base rule
• Equal proportions rule
• Triplets rule
• Codon rule

DNA molecules have the appearance of a spiral ladder or double helix, a sugar–phosphate backbone or frame, and rungs or steps that are made up of nitrogenous bases joined together by hydrogen bonds.

• Double helix
• Loop-de-loop
• Single helix
• Spiral

A sequence of three nucleotides in DNA that can code for an amino acid. 

• Triplet
• Base pair
• Amino rule
• Gene
