Gene Regulation

Question 1

Alternative Splicing

Answer 1

Determines which proteins
are made from which gene
by changing which exons
remain in an mRNA strand; Eukaryote; Pretranslational; What protein is made?

Question 2

Introns

Answer 2

Intervening DNA sequences
that are typically removed
from a mature mRNA

Question 3

Exons

Answer 3

Coding sequences that can
be rearranged in multiple
ways to produce different
proteins

Question 4

Transcription Factors

Answer 4

Controls whether genes
turn on or off based on
whether activators can
bind to the enhancer
sequences; Eukaryote; Pretranscriptional; When, What, & How

Question 5

Transcription Factor Protein

Answer 5

binds to DNA
to initiate transcription

Question 6

Enhancers

Answer 6

DNA sequences that allow
transcription to take place
or increase the amount of it
when bound to activators

Question 7

Activators

Answer 7

Proteins that bind to enhancers and loop the DNA around to activate transcription

Question 8

Epigenome

Answer 8

Uses Methylation and
Acetylation to make
DNA accessible or
inaccessible; Eukaryote; Pretranscriptional; When, What, & How

Question 9

Histones

Answer 9

Wrap up DNA to
make it accessible or
inaccessible

Question 10

Methylations

Answer 10

Collapse DNA to
make it inaccessible

Question 10

Methylations

Answer 10

Collapse DNA to
make it inaccessible

Question 11

Acetylations

Answer 11

Expand DNA to make it accessible

Question 12

Operons

Answer 12

Determines which genes are
turned on under what
conditions. (on/off switch); Prokaryote; Pretranscriptional; When it’s made

Question 13

Promotor

Answer 13

DNA sequence where RNA
Polymerase Binds

Question 14

Operator

Answer 14

Location where a repressor
binds to stop transcription

Question 15

Repressor

Answer 15

Protein that binds the
operator to stop
transcription

Question 16

Inducer

Answer 16

A molecule that can remove a repressor from the operator
