topic 7.2: Transcription and gene expression
Essential Idea:
- Information stored as a code in DNA is copied onto mRNA
7.2U1: Transcription occurs in a 5' to 3' direction.
7.2U2: Nucleosomes help to regulate transcription in eukaryotes.
7.2U3: Eukaryotic cells modify mRNA after transcription.
7.2U4: Splicing of mRNA increases the number of different proteins an organism can produce.
7.2U5: Gene expression is regulated by proteins that bind to specific base sequences in DNA.
7.2U6: The environment of a cell and of an organism has an impact on gene expression.
7.2A1: The promoter is an example of non-coding DNA with a function.
7.2Skill 1: Analysis of changes in DNA methylation patterns.
