Dils - DNA Heredity Molecule Mini-Test

A nucleotide is

• a unit of DNA (phosphate, sugar, and base)

• a full double helix DNA molecule

• a strand or helix of a DNA molecule

Two pieces that make up the side/backbone for a DNA double helix are

• adenine and thymine

• phosphate and sugar

What scientist was the first to photograph DNA's structure?

• Rosalind Franklin

• Francis Crick

• James Watson

The four nitrogen bases that pair up to form the rungs in the DNA double helix are

• C+T and A+G

• C+G and A+T

• T+G and C+A

DNA replication is

• a parent molecule make two identical daughter DNA molecules

• a parent DNA molecule making two different daughter DNA molecules

• a parent DNA molecule making a different daughter DNA molecule

The steps to DNA Replication are

• Complementary bases are added, the parent molecule unwinds, and the bases are read

• The parent molecule unwinds, the bases are read, and complementary bases are added

• Bases are read, complementary bases are added, and the parent molecule unwinds

The order of the bases along a gene is called

• protein synthesis

• base sequence

• DNA replication

The complementary base sequence for T-T-A-C-G is

• A-A-T-G-C

• C-G-T-A-A

• T-T-A-C-G

A mutation is

• DNA dividing

• DNA copying itself

• a change in the organism's genetic material
