5.4 Regulation of Transcription Flashcards
What is the process of transcription?
conversion of genetic material in DNA to RNA
What is the outcome of transcription?
messenger RNA
What does it mean to be complimentary?
for each base, the letter that forms the corresponding hydrogen bonds will be made
Where does translation into proteins occur?
ribosomes in the cytoplasm
What enzyme is reponsible for the synthesis of DNA to RNA?
RNA polymerase
Is primer required for initiation of RNA polymerase?
no
In E coli what is RNA polymerase made of?
core enzyme and the sigma unit
What is the core enzyme?
comprised of four subunits
What is the holoenzyme?
the core enzyme and the sigma unit together
How many RNA polymerases are in eukaryotes?
three
Which strand does transcription occur on?
the template strand
What is the other strand known as? (not the template one)
coding strand
Which strand has an identical sequence to the mRNA that is being sequenced?
coding strand
What is the first step in bacterial gene transcription?
template binding
What occurs during template bindning?
sigma subunit of RNA polymerase recognizes a promoter
