Select the terms that represent a mode of regulation of gene

Select the terms that represent a mode of regulation of gene expression of gene expression in eukaryotes. Incorrect. At least one of your selections is incorrect. the core structure of DNA and the structure of bases are not altered to regulate gene expression.

Solution

Gene expression is frequently managed frequently at the level of transcription. However, that does not suggest transcription is the final risk for regulation. Later stages of gene expression can also be regulated, inclusive of:
RNA processing, consisting of splicing, capping, and poly-A tail addition
Messenger RNA (mRNA) translation and lifelong inside the cytosol
Proteins can be tagged for degradation by means of the addition of a chemical marker called ubiquitin. Ubiquitination is an vital way of controlling the patience of a protein inside the cell.

So answer is mRNA splicing, ubiquitination, Transcription
