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