QuestionAnswer
Transcription occurs when RNA pol matches the base in a ribonucl. triphosphate with the complem. base in a gene
How does the initiation begins? RNA pol and sigma form a holoenzyme which contains the active site for catalysis
What the name of the sites where the holoenzyme binds to? promoters
Promoters are sections of DNA wehre the trascription begins
Sigma is responsible for guiding RNA pol to specific locations where transcription should begin
The promoter for bacteria is a segment of DNA located on a non-template strand similar to Tataat and known as -10 box
Sigma opens what to start the transcription? the helix
The -10 box is centered 10 bases upstream from what? the transcription start site
The place where the transcription begins is called +1 site
-35 bases upstream are called what -35 box
Then the transcription begins when sigma does what? binds to the -35 and -10 boxes
Sigma is what regulatory protein
Sigma tells RNA pol in bacteria where and when to start synthesizing Rna
Sigma is released once Rna synthesis is under way and initiation is complete
During elongation phase, RNA pol moves along DNA template in the 3 to 5 direction of the template strand, synthesizing RNA in the 5 to 3 direction
Transcription ends with a termination phase where formation of a hairpin in the mRNA disrupts the transcription
The bases that make up the termination signal code for a stretch of RNA with an unusual property: as soon as its synthesized, the RNA sequence folds back on itself and forms a short double helix

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
