You are free to take this quiz based on the GC box 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 Which of the following are phenomena associated with CpG sites?

cytosine nucleotide occurs next to a guanine nucleotide
"—C—phosphate—G—"
CG base-pairing
C and G are found on the same strand of DNA or RNA and are connected by a phosphodiester bond

CpG islands
three hydrogen bonds

2 True or False, A repeating sequence of nucleotides that forms a transcription or a regulatory signal is called a box.

TRUE
FALSE

TRUE
FALSE

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
