Gene transcriptions/Start sites/Quiz

Transcription start site is a lecture as part of the gene transcription series.

You are free to take this quiz based on the transcription start site at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

 * type="[]"}

{Complete the text: The transcription start site is the { location (i) } where transcription { begins|starts (i) } at the { 5'|five-prime|five prime (i) }-end of a { gene (i) } sequence.
 * type="{}"}

{Complete the text: Match up the type of promoter or promoter element with each of the possibilities below: TATA box - A initiator element - B enhancers and inhibitors - C downstream elements - D General transcription factor II D - E ATA box - F downstream core promoter { D (i) }. includes the transcription start site { B (i) }. proximal promoter { F (i) }. distal promoter { C (i) }. core promoter { E (i) } usually 25 nucleotides upstream { A (i) }.
 * type="{}"}

Hypotheses

 * 1) A1BG may have up to four transcription start sites.
