HELP with BIO !!!
1)Describe the levels of DNA packaging in Eukaryotic cells and explain how packaging is related to gene expression
2)Diagram the structure of the Lac operon and explain how it is regulated both positively and negatively
3)Discuss the different ways that eukaryotic gene expression can be regulated.
4)Diagram the steps in both transcription and translation including all proteins and nucleic acids involved as well as the direction of synthesis.
5)Why are the enzymes that link uncharged tRNAs to unique AAs critical to protein synthesis?

It's been a while since I did biological science.

The first question look up histone acetylation and DNA methylation.
The packaging of chromatin determines how easy it is to transcribe.
