Definition
| DNA contains four different types of nucleotides: two with purine bases, adenine (A) and guanine (G), which have a double ring, and two with pyrimidine bases, thymine (T) and cytosine (C), which have a single ring. 227 |

Term
|
Definition
1. The amount of A, T, G, and C in DNA varies from species to species.
2. In each species, the amount of A=T and the amount of G=C. 227 |

Definition
| they deducted that DNA is a double helix with sugar-phosphate backbones on the outside and paired bases on the inside. 228 |

Term
| Complementary Base Pairing |
|
Definition
| means that a purine is always bonded to a pyrimidine. 228 |

Term
|
Definition
| during DNA replication, the parental DNA molecule unwinds and unzips. THen each old strand serves as a template. 230 |

Term
| Semiconservative Replication |
|
Definition
| DNA replication is termed semiconservative replication because one of the old strands is conserved, or present, in each daughter DNA molecule (new double helix). 230 |

Term
|
Definition
| Steps 2 and 3 are carried out by an enzyme complex called DNA polymerase. 230 |
|
|
Term
|
Definition
| DNA replication is semiconservative. Each daughter strand contains an old strand and a new strand. 231 |
