Topic 6.1
DNA and RNA Structure
Compare DNA and RNA, apply base-pairing rules, and explain how sequence stores information.
Topic 6.2
DNA Replication
Assign each replication enzyme its role and interpret the labeling evidence for semiconservative copying.
Topic 6.3
Transcription & RNA Processing
Model transcription from a DNA template and follow eukaryotic RNA processing.
Topic 6.4
Translation & Information Flow
Use the genetic code to connect mRNA, tRNA, ribosomes, and polypeptide sequence.
Topics 6.1–6.4
Central Dogma Synthesis
Trace one sequence through replication, transcription, and translation, then predict the effect of a change.
Topic 6.5
Prokaryotic Gene Regulation
Predict expression from operon structure, regulatory proteins, and inducible or repressible logic.
Topics 6.5–6.6
Eukaryotic Regulation & Cell Specialization
Connect chromatin access, transcription factors, and small RNAs to differential expression.
Topic 6.7
Mutations, Variation & Selection
Classify sequence and chromosome changes and predict their phenotypic consequences.
Topic 6.8
Biotechnology Evidence Lab
Choose the right tool and make proportional claims from PCR, gel, and transformation evidence.
Topics 6.1–6.8
Unit 6 Assessment
Apply sequence models, expression data, regulation, mutations, and biotechnology to new evidence.
