AP molecular DNA (pearson ch 13-15)
- ch 13: The Molecular Basis of Inheritance
- DNA is the genetic material
- experiments involved in discovering this
- types of bonds found in a molecule of DNA
- how that is related to its function
- complementary base pairing
- how it is related to continuity of maintaining
the heritable information
- DNA replication
- what is meant by DNA being semiconservative
- the experiment done to discover it.
- enzymes involved such as ligase, primase, DNA Polymerase, topoisomerase, and helicase
- Predict what would happen if certain enzymes needed for replication did not function
- leading strand v. lagging strand
- excisions repair
- enzymes involved
- Predict what would happen if errors in DNA replication could not be repaired
- ch 14: Gene Expression: From Gene to Protein
- transcription
- process
- transcription factors
- how they relate to the promoter region and RNA Polymerase
- Predict the mRNA strand given the DNA strand and visa-versa
- Explain how transcription differs between eukaryotic and prokaryotic cells
- including enzymes and related proteins such as RNA polymerase
- What strand of DNA is mRNA copied from? In what direction does the mRNA get made in? What is the
promoter region?
- Explain what a codon is
- translation
- Explain how translation differs between eukaryotic and prokaryotic cells
- how the mRNA code is read to create a protein.
- Be able to tell what amino acids would be present in a protein is given
the mRNA sequence.
- why there are 3 nitrogen bases per codon in terms of their being 20 amino acids
- what is meant by the statement: “ the genetic code is redundant but unambiguous”
- Determine the anticodon in tRNA if given the DNA or mRNA and visa-versa
- parts of the ribosome involved in transcription
- structure of tRNA and how it matches up with the complementary mRNA.
- What contains the codon? The anticodon?
- different types of mutation and what each results in
- how proteins destined for export are tagged.
- RNA processing
- 3 ways
- Predict what would happen if the processed mRNA did not have a 5’ cap or a poly A tail
