BIO 351 GENETICS SDSU EXAM 2
Francis Crick's original central dogma of biology
DNA > Transcription > RNA > Translation > Protein
What does the central dogma of biology describe?
The flow of genetic information
Which RNA undergoes translation?
mRNA
What is reverse transcription?
RNA that contains retroviruses that have reverse transcriptase enzyme to
convert RNA to DNA
Transcription
Information in a DNA sequence is converted into an RNA sequence, occurs for
individual genes
What are the two important players for bacterial transcription?
DNA and RNA polymerase
Where is the promoter located?
Upstream, within few nucleotides of 5' start
Which region of the gene is transcribed into mRNA?
Coding region
Which region of the gene regulates cessation of transcription?
Termination region
Template strand
DNA strand from which the RNA are synthesized
In what direction is the transcript synthesized?
5' to 3'
