DNA and Mutations

What does DNA stand for?

• Ribonucleic acid

• Deoxyribonucleic acid

• Donuts ribosomes acid

Where do we find DNA?

• in the nucleus of cells

• in the ribosomes

• in the endoplasmic reticulum

What are the four bases found in DNA?

• U, A, T, B

• B, O, A, T

• A, G, C, T

• U, V, W, X

Which bases pair together?

• A--> T, C--> G

• A --> G, C --> T

• A--> C, G --> T

A matches with T, C matches with G. Show the complementary strand for the following:

AGCTCATA

How many strands are in DNA?

• one

• two

What are the names of the two scientists that are credited with discovering the structure of DNA?

• Einstein and Curie

• Dalton and Darwin

• Watson and Crick

What type of bonding holds the complementary bases together?

• ionic bonding

• covalent bonding

• hydrogen bonding

Which shows a mutated segment of DNA? 
ATTCGC

• UAAGCG
• TAAGCG
• TAGGCG

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence
• They insert things that an organism doesn't need.
• They often delete things that organisms need.
• Insertion and deletions are not any more harmful than substitution mutations.
