Topic 7.2: Transcription and Gene Expression
Essential Idea: Information stored as a code in DNA is copied onto mRNA.
At SHS, Topic 7.2 is taught in the following class unit(s):
Statements & Objectives:
7.2.U1 Gene expression is regulated by proteins that bind to specific base sequences in DNA.
7.2.U2 The environment of a cell and of an organism has an impact on gene expression.
7.2.U3 Nucleosomes help to regulate transcription in eukaryotes.
7.2.U4 Transcription occurs in a 5’ to 3’ direction.
7.2.U5 Eukaryotic cells modify mRNA after transcription.
7.2.U6 Splicing of mRNA increases the number of different proteins an organism can produce.
7.2.A1 The promoter as an example of non-coding DNA with a function.
7.2.S1 Analysis of changes in the DNA methylation patterns.
7.2.NOS Looking for patterns, trends and discrepancies- there is mounting evidence that the environment can trigger heritable changes in epigenetic factors.
