You are free to take this quiz based on the transcription of A1BG 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 gene project 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!

Quiz

1 Yes or No, A stable preinitiation complex can form in vitro on TATA-dependent core promoters by association of the basal factors in the following order: TFIID/TFIIA, TFIIB, RNA polymerase II/TFIIF, TFIIE, and then TFIIH.

Yes
No

dispersed promoter
proximal promoter
downstream promoter
distal promoter
enhancer
focused promoter
core promoter

3 Yes or No, The two complementary strands of double-stranded DNA (dsDNA) are usually differentiated as the "sense" strand and the "antisense" strand.

Yes
No
