Nucleotide base pairing |
These are the building blocks for DNA. They are ATCG. A and T are paired together and C and G are paired together. |
Pairs that build DNA |
|
|
Hydrogen bond |
A weak attraction between hydrogen atoms and oxygen, nitrogen, or fluorine atoms. Holds strands together of DNA in their double helix. |
Hydrogen attraction |
|
|
Antiparallel |
When two lines run parallel with each other with opposite alignments. An example is two of the complementary strands of the DNA double helix. |
Two strands DNA double helix |
|
|
DNA polymerase |
An enzyme that catalyzes the synthesis of a new DNA strand using one of the original strands as a template |
Copying a strand |
|
|
Semiconservative replication |
Producing two copies that each contained one of the original strands and one new strand |
Half copies |
|
|
Histone |
highly alkaline proteins found in eukaryotic cell nuclei thatpackage and order the DNA into structural units called nucleosomes. |
Proteins |
|
|
Chromosome |
Made of proteins and a single molecule of DNA. Passed from parents to offspring. |
Made of proteins and DNA |
|
|

|
|
Mutation |
A structural change in a gene, a chromosome, or another genetic unit |
Change |
