7.2 Transcription and Translation
- Nature of Science
- Looking for patterns, trends and discrepancies
- Epigenetic factors
- Analysis of changes in the
DNA methylation patterns
- TOK
- Nature vs Nurture
- Relative importance of an individual`s innate qualities vs
those acquired through experiences is still under discussion
- Transcription occurs in a 5' and 3' direction
- RNA polymerase adds the 5' end of the free RNA
nucleotide to the 3' end of the growing mRNA molecule
- Regulation
- Nucleosomes help to regulate
transcription in eukaryotes
- Eukaryotic cells modify
mRNA after transcription
- Splicing of mRNA incease the number of
different proteins an organism can produce
- The promoter as an example of
non-coding DNA with a function
- The environment of a cell and of an organism
has an impact on gene expression
- Gene expression is regulated by proteins
that bind to specific base sequences in DNA
