Epigenetics is a lecture as part of the gene transcription series.

You are free to take this quiz based on the epigenetics 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[edit]







  

1

Yes or No, Epigenetics is the study of genome or epigenome changes resulting from external rather than genetic influences.

Yes
No

2

The portion of a promoter in which an epigenetics element is likely to be found is which of the following?

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

3

Several promoter elements have been previously identified in eukaryotes, but those cannot account for transcription from most RNA polymerase II-transcribed

4

Yes or No, Inside each eukaryote nucleus is genetic material (DNA) surrounded by protective and regulatory proteins.

Yes
No

5

True or False, Some epigenetics elements are located in the dispersed promoter.

TRUE
FALSE

6

Which of the following is not a transcriptional characteristic of epigenetics elements?

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
triphosphate

7

Complete the text:

Genetics elements involve the

, transmission, and

of inherited characteristics.

8

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

.
includes the transcription start site

.
proximal promoter

.
distal promoter

.
core promoter

usually 25 nucleotides upstream

.

9

Which of the following are phenomena associated with epigenetics elements?

transcription of A1BG
directing activator-dependent but TFIID-independent transcription
TATA box-less promoters
initiator element
mediator dependence
core promoter

10

Yes or No, There are nearly 50,000 acetylated sites, punctate sites of modified histones, in the human genome that correlate with active transcription start sites and CpG islands and tend to cluster within gene-rich loci.

Yes
No

11

True or False, Epigenetics elements are found in the promoter regions of at least 1% of human genes.

TRUE
FALSE


Hypotheses[edit]

  1. A1BG is a gene unique to mammals.
