Gaia Theory and All Life is Connected

The concepts of an interconnected earth are intriguing and measurable. As a botanist and microbiologist I have studied symbiotic relations that range from parasitic to symbiotic. Many indigenous people have understood these concepts longer than modern scientists. The Lakota Sioux state: “Mitakuye Oyasin,”which means, “To all of my relations.” It is a prayer of oneness and harmony with all forms of life: people, animals, birds, plants, insects, and even rocks. It is a reminder that we all share a common kinship within the hoop of life. Our bodies are composites of bacteria, and within our cells are remnants of ancient bacterial cells that are now mitochondria. Dr. Lynn Marguelis a famous botanist, and suppoter of James Lovelock Theory of Gaia states: "The only individuals on the planet are bacteria."

DNA Replication

March 23, 2012



Goal: Discover the enzymes that coordinate the replication of the "Thread of life,"

BELL QUIZ: Benchmark Biology Exam
Historical Flow: Watson & Crick, Rosalind Franklin Video (add main points to time-line flowchart).
Review DNA Structures
Complete Chargoff Data Abstract and Ratios Graph

DNA Replication Homework: DNA replication is the process whereby an entire double-stranded DNA is copied to produce a second, identical DNA double helix. Students will illustrate and label the seven steps of DNA Replication from the sequences from the video, 'DNA Replication from "Essential Biochemistry.'

http://www.wiley.com/college/pratt/0471393878/student/animations/dna_replication/index.html

The objectives of this exercise are to illustrate the stages of DNA Replication:

  1. Understand the functions of the seven proteins responsible for DNA replication, including helicase, SSB protein, primase, the sliding clamp, DNA polymerase, Rnase H and DNA ligase.
  2. Discover why the leading strand is synthesized continuously and the lagging strand is synthesized discontinuously.
