What does DNA stand for?

• Deoxynitrogenous Acid

• Deribo Nuclein Acid

• Deoxyribonucleic Acid

• Denatured Nucleic Acid

The bases form complimentary base pairs. Which pairs shown are correct?

• A. A - T and C - G

• B. A - C and T - G

• C. A - G and C - T

Which type of bonds form between complementary base pairs?

• Oxygen

• Hydrogen

• Phosphodiester

• Covalent

Why does DNA replication happen?

• To prepare for cell division

• To repair faulty DNA

• To extend the DNA so more cellular activities can occur

• To replace the old, worn out DNA

DNA replication is known as semi-conservative because...

• The process only takes place in cells once a fortnight

• The DNA is proofread before completion ensuring high fidelity

• It only happens when the organism is injured and in need of new cells

• The new DNA strands each contain a strand of the original DNA

Which type of mutation involves the addition of one or more nucleotide base pairs into a DNA sequence?

• Insertion

• Deletion

• Substitution
