Term
|
Definition
| The shape of DNA (James Watson and Francis Crick discovered this) |
|
|
Term
|
Definition
| The enzymes that make the covalent bond berween nucleotides of a new DNA strand |
|
|
Term
|
Definition
| Replication resultsin two daughter DNA molecules, each consisting of one old strand and one new strand. The parental DNA untwists as its strands seperate, and the daughter DNA rewinds as it forms. |

|
|
Term
|
Definition
| The set of rules relating nucleotide sequences to amino acid sequences |
|
|
Term
|
Definition
| The transcription enzyme which links the RNA nucleotides |
|
|
Term
|
Definition
| The "start transcribing" signal in a nucleotide sequence |
|
|
Term
|
Definition
| The first phase of Transcripstion: it's the attachment of RNA polymerase to the promoter and the start of RNA synthesis |
|
|
Term
|
Definition
| The scecond phase of Transcription:the RNA grows longer and as RNA synthesis continues the RNA strand peels away from its DNA template |
|
|
Term
|
Definition
| The third phase of Transcription:is a special sequence of bases in the DNA template which signals the end of the gene. |
|
