< Gene transcriptions/Boxes | V and Ps

V and P boxes is a lecture of the gene transcription series.

The monito del monte (Dromiciops gliroides) is an enigmatic marsupial native to Argentina and Chile that may be more closely related to Australian marsupials than other South American marsupials. Credit: José Luis Bartheld from Valdivia, Chile.

You are free to take this quiz based on the V and P boxes 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

Yes
No

2 The portion of the promoter in which the V and P boxes are likely to be found is which of the following?

downstream promoter
distal promoter
enhancer

3 Yes or No, The V and P boxes triplet repeat is found in the coding region of the human E2F-4 gene.

Yes
No

located between nucleotides -8 and +2 relative to the transcriptional start site (+1)
G/A/T-G/C+1-G-T/C-G-G-G/A-A-G/C
in eukaryotes
TATA-less genes
