DNA Structure and Function

DNA is

• ribonucleic acid
• deoxyribonucleic acid
• deoxyribonucleic atom
• dinitrogenous acid

The basic building blocks of DNA are 

• amino acids
• lipids
• carbohydrates
• nucleotides

In DNA, nucleotides are held together by

• ionic bonds
• weak hydrogen bonds
• carbonic bonds
• oxygenated bonds

Adenine bonds with

• adenine
• thymine
• guanine 
• cytosine

Guanine bonds with

• Adenine 
• Thymine
• Guanine
• Cytosine

The structure of our DNA can be described as

• a ladder

• a double helix

• a circle

• an infinite chain

What are the nucleotides made of?

• Sugar, Phosphate, nitrogen base
• Phosphate, Adenine, nitrogen base
• Thymine, Adenine, Cytomine
• Phosphate, Nitrogen, Adenine

Which of the following best describes a DNA molecule?

• double helix
• contains ribose
• made of amino acids
• contains Uracil

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

What are the 4 nitrogen bases?

• adenine, thymine, cytoplasm, and guanine
• adenine, thymine cytosine, and guanine
• adenine, thymine, cytosine, and gylcerol
• adenine, thymine, cytosine, and glucose
