| True / False |
Statement |
| |
 |
DNA stands for deoxyribonucleic acid.
|
| |
|
One complete DNA molecule consists of a single helix.
|
| |
|
The building blocks of DNA are called nucleotides.
|
| |
|
One nucleotide is composed of two parts: a sugar and a nitrogen base.
|
| |
|
The sugar in DNA is called ribose.
|
| |
| True / False |
Statement |
| |
|
With respect to the bases, A binds with T and C binds with G.
|
| |
|
Complementary bases are held together by hydrogen bonds.
|
| |
|
With one nucleotide, the nitrogen base is attached to the phosphate group.
|
| |
|
The "backbone" or outer strands of DNA are repeating sugars and bases.
|
| |
|
The genetic code lies in the order of nitrogen bases.
|
| |
| True / False |
Statement |
| |
|
Four bases in a row make up one codon.
|
| |
|
Each codon codes for one amino acid.
|
| |
|
Many amino acids bonded together form a protein.
|
| |
|
All genetic mutations are harmful.
|
| |
|
Genetic mutations may be harmful, neutral, or beneficial.
|
| |
| True / False |
Statement |
| |
|
A genetic mutation always causes the production of a different protein.
|
| |
|
Mutagenic agents are drugs taken by a patient to treat a genetic mutation.
|
| |
|
Only mutations in the gametes can be passed on to children.
|
| |
|
A cell with 46 chromosomes has 46 DNA molecules.
|
| |
|
