AP Biology Unit 3.1: The Continuity of Life Part 1 - DNA and Protein Synthesis

Homework Oct. 21-22
  • Take the first part of the DNA/Protein Synthesis Test on Edmodo
  • Prepare for the second part in class on Monday
  • Also watch the following videos on Cell Cycle, Mitosis and Meiosis
  • Watch the videos below (the first video has some topics in the second half that we will push to the regualtion unit later in the year. Go ahead and watch it but don't worry about the details of the growth regulators. We will expand on this topic in Unit IX. The beginning and basics will help set up the other two vids and the big ideas.)
  • Work on note packets and pretest (homework/classwork grade)

Homework Oct. 17-19
  • Prepare for quiz on Protein Synthesis
  • Watch the video below

Homework Oct. 11-13
  • Watch the 3 videos below on Protein Synthesis (scroll down)
  • Take notes in your note packets.
  • We still have to review and quiz the DNA replication video (so you may want to review it again)

Part 1 - History of DNA, DNA Structure, DNA Replication, DNA Function, Protein Synthesis, and Introduction to Gene Control.
October - 9 - Quiz tomorrow will cover the first two videos below.

Homework Oct. 6-7
  • Watch the first 3 videos below
  • Take notes in your new note packets.


  Essential Questions:

  • How are all living things connected by the genetic code?
  • How does the genetic code determine organismal traits?
  • How does the work of many scientists combine for our modern understand of genetic systems?
  • How does the genetic code change?
  • What is the nature of gene control and cell differentiation?
  • How do cells pass along copies of their genetic material?
  • How does sexual recombination create genetic diversity?
  • How do we understand genetics and the process of inheritance?
  • How does our understanding of DNA structure and function, meiosis, and fertilization help us understand the process of trait inheritance?
  • What variations on Mendel’s themes do we know?
  • What is the nature of sex chromosomes and what implications does that have for genetics?
  • What are linked genes?
  • What happens when the process goes wrong?
  • Define and illustrated the structure of nucleic acids..
  • Explore the historical research discoveries that led to the understanding of the structure and function of DNA.
  • Explain in detail the structure and function of DNA.
  • Explain in detail the role of RNA in protein synthesis.
  • Discuss the universality of the DNA code and how that relates to the interconnectedness of all living things.
  • Explain the “central dogma.”
  • Describe in detail the process of DNA replication.
  • Describe in detail Protein synthesis – Transcription and translation.
  • Explain how structure relates to function in DNA replication and transcription and translation.
  • Discuss the role of enzymes in the processes above.
  • Discuss how mistakes can be made and repaired during DNA replication.
  • Discuss how mistakes/modifications can be made during transcription and translation.
  • Discuss the sources of mutations – environmental and otherwise.
  • Understand the immediate and long term impact of mutations and modifications on the final product.
  • Describe the organization of DNA and proteins into Chromosomes.
  • Explain how this structure relates to its functioning.
  • Differentiate between cell division and nuclear division.
  • Discuss how our understanding of DNA structure, function, and replication relates to cell division.
  • Compare and contrast asexual and sexual reproduction as it relates to the inheritance of genetic material and genetic diversity.
  • Explain the importance of meiosis and fertilization
  • Describe in detail the events of meiosis.
  • Illustrate the processes of meiosis, and fertilization
  • Discuss how genetic variation impacts the overall population.
  • Describe in detail Mendel’s contribution to our understanding of genetics in a historic context.
  • Explain the concept of dominance and how it led to our understanding of the particulate nature of genes.
  • Define genotype and phenotype.
  • Explain in detail the laws of segregation and independent assortment. 
  • Illustrate how these laws can be explained by the physical processes during meiosis.
  • Employ the use of Punnett squares to analyze genetic combinations and offspring probabilities.
  • Explain a few simple laws of probability that govern simple Mendelian genetics.
  • Explore the various variations on Mendel’s discoveries – incomplete dominance, co-dominance, polygenics, multiple alleles, plieotropy.
  • Employ punnett squares to analyze these variations.
  • Explain pedigrees.
  • Use pedigree analysis to track and predict the expression of a trait or the presence of a gene.
  • Investigate Morgan’s experiments on fruit flies and explain the concept of sex-linked traits.
  • Differentiate between autosomes and sex chromosomes.
  • Investigate the effect of linked genes on independent assortment.
  • Explain how we can use cross-over data to map the relative location of linked genes on a chromosome.
  • Discuss chromosomal mutations.
  • Discuss how variations in chromosome structure affect individuals - with specific examples.
  • Describe variations in chromosome number and the effects of these variations – use specific examples.
