Gene transcriptions/Boxes/C/Ds/Quiz

C and D boxes is a lecture as part of the gene transcription series.

You are free to take this quiz based on the C and D 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 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 or No, The GCC box is also referred to as the C and D boxes. + No - Yes
 * type=""}

{The portion of the promoter in which C and D boxes are likely to be found is which of the following? + core promoter - proximal promoter + downstream promoter - distal promoter - enhancer
 * type="[]"}

{Yes or No, The C and D duplet repeat is found in the coding region of the human E2F-4 gene. - Yes + No
 * type=""}

{Several promoter elements have been previously identified in eukaryotes, but those cannot account for transcription from most RNA polymerase II-transcribed { genes|gene (i) }
 * type="{}"}

{True or False, Some C and D boxes are located in the distal promoter. + TRUE - FALSE
 * type=""}

{Which of the following is not a transcriptional characteristic of C and D boxes? + 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 - a consensus sequence
 * type="[]"}

{Complete the text: A transcript follows one of two possible pathways: (i) a precursor capped with { monomethylguanosine (i) } (open circle) is hypermethylated to yield { trimethylguanosine (i) } (closed circle) and trimmed at the 3' end by { exonucleases (i) }, or (ii) if uncapped, the precursor is { trimmed (i) } at both ends.
 * 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="{}"}

{Which of the following are phenomena associated with C and D boxes? - transcription of A1BG - directs activator-dependent but TFIID-independent transcription - TATA box-less promoters - initiator element - mediator dependence + proximal promoter
 * type="[]"}

{True or False, C and D boxes are found in the promoter regions of at least 1% of human genes. - TRUE + FALSE
 * type=""}

Hypotheses

 * 1) A1BG is not transcribed using C and D boxes.
