Gene Regulation in Eukaryotes

Gene regulation is more complicated in which type of cell?

• eukaryotic

• prokaryotic

The transcription factor, activators...

• make it easy for RNA polymerase to bind to the promoter

• make it difficult for RNA polymerase to bind to the promoter

The transcription factor, repressors...

• make it easy for RNA polymerase to bind to the promoter

• make it difficult for RNA polymerase to bind to the promoter

When nucleosomes are tightly packed together...

• genes are expressed

• genes are NOT expressed

When nucleosomes are loosely packed ...

• genes are expressed

• genes are NOT expressed

Hox genes...

• activate/repress transcription

• controls differentiation in embryo body part development

• small segments of double stranded RNA that is broken down into single stranded RNA that stop mRNA from being translated
