, At what levels does regulation of gene expression occur? - correct answers ✔✔At
the DNA, RNA, and post transcriptional levels.



In what ways does regulation of gene expression at the DNA level occur? - correct
answers ✔✔Acetylation - induces transcription

and

Methylation - inhibits transcription



In what ways does regulation of gene expression at the RNA level occur? - correct
answers ✔✔Activator proteins - proteins that increase transcription by binding to
other regulatory regions

and

Repressor proteins - proteins that decrease transcription by binding to control
element regions or blocking activator proteins from binding



In what ways does regulation of gene expression occur at the post- transcription
level? - correct answers ✔✔Alternative splicing - splicing and rejoining of
different regions from one primary transcript -> influences the amount of
function proteins produced



In what ways does regulation of gene expression occur after RNA processing? -
correct answers ✔✔Activation or inactivation of proteins that are needed to start
transcription
