Module 09 - DNA Structure, Function & Synthesis

DNA is a polymer. The monomers that make up DNA are

• fatty acids
• sugars
• amino acids
• nucleotides

What do we call this 'piece' of DNA?

What is the MONOMER of DNA?

• Phospate

• Sugar

• Polymer

• Nucleotide

The parts of a nucleotide are

• sugar, salt, nitrogenous base
• protein, phosphate group, nitrogenous base
• water, phosphate group, nitrogenous base
• sugar, phosphate group, nitrogenous base

If you think of DNA like a ladder, the sides of the ladder are made of

• sugars and phosphate groups

• phosphate groups and hydrogen bonds

• sugars and adenine

• nitrogenous bases

What do the letters DNA stand for?

• Deoxyribonucleic Acid
• Dietary Nutritional Analysis
• Dancing with Angels
• Digital Network Association

If you think of DNA like a ladder, the inside rungs (or steps of the ladder) are made of

• nitrogenous bases (A,C,T,G) held together by hydrogen bonds

• proteins held together by covalent bonds

• lipids held together by lipid bonds

• RNA → DNA → proteins → traits

• DNA → RNA → proteins → traits

• RNA → traits →proteins → DNA
