The Central Dogma: DNA to RNA to Protein
Understand the flow of genetic information from DNA through transcription to mRNA and then through translation to protein.

Transcription in Detail
Learn the steps of transcription: initiation (promoter binding), elongation (mRNA synthesis), and termination. Understand RNA polymerase and promoter elements.
mRNA Processing in Eukaryotes
Study the three major modifications to pre-mRNA: 5' capping, 3' polyadenylation, and intron splicing via the spliceosome.
Translation and the Genetic Code
Master the genetic code, codon-anticodon pairing, ribosome structure (A, P, E sites), and the steps of translation: initiation, elongation, termination.
Prokaryotic Gene Regulation: Operons
Understand the lac operon (inducible, negative and positive control) and trp operon (repressible) as models of prokaryotic gene regulation.
Eukaryotic Gene Regulation
Explore the multiple levels of eukaryotic regulation: chromatin remodeling, transcription factors, enhancers/silencers, post-transcriptional processing, and translational control.
Epigenetics and Chromatin Modification
Study DNA methylation, histone acetylation/deacetylation, and other epigenetic mechanisms that regulate gene expression without altering DNA sequence.
Gene Expression in Development and Disease
Connect differential gene expression to cell differentiation, embryonic development, and diseases like cancer where gene regulation goes wrong.
