DNA: The Genetic Record
|
Timeline of DNA discovery from the beginning to more current understanding...
Genes and Coding/ Non-coding Regions
Transcription and Translation
|
Transcription: the conversion of the information on DNA into a mRNA (message). This process occurs in the nucleus
Translation: the creation of a string of amino acids (proteins) from the mRNA.
Translation: the creation of a string of amino acids (proteins) from the mRNA.
STR's and VNTR's... used to distinguish two people... which will then be shown in the gel electrophoresis analytical technique
Polymerase Chain Reaction:
The polymerase chain reaction (PCR) is a biomedical technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.
PCR is the first step to DNA Fingerpringting (gel electrophoresis)(restriction fragment length polymorphism)... we want to amplify DNA first, then analyze. |
