7.2 Factors affecting gene expression
i Know that transcription factors are proteins that bind to DNA.
ii Understand the role of transcription factors in regulating gene expression.
iii Understand how post-transcription modification of mRNA in eukaryotic cells (RNA splicing) can result in different products from a single gene.
iv Understand that gene expression can be changed by epigenetic modification, including non-coding RNA, histone modification and DNA methylation.
v Know that epigenetic modification is important in ensuring cell differentiation.
