Replication activity-- although we end up with a poster, the goal of this activity is to re-enact replication the group of students (i usually do groups of 4 since there is a lot of cutting) must act out replication for the teacher using these players and only in the end do they memorialize everything as a poster.

Dna replication is accomplished by dna polymerase this process is assisted by rna polymerase, helicase, dna ligase and topoisomerase dna replication proceeds in one direction only, necessitating the formation of okazaki fragments during the replication of the lagging strand. Primase is an enzyme that is essential for the process of dna replication it synthesizes rna primers so that dna polymerase may begin replicating dna mutation to the gene that codes for primase would damage the protein. Hw: read chap 18, and begin chapter 18 mastering biology online possible essay questions for unit 6 exam: see synthesis/evaluation section at the end of each chapter.
As the replication fork of dna proceeds and continues to unwind the double helix, the dna upstream of the fork gets over wound and knotted up which will eventually arrest replication as the fork will not be able to proceed any further.

Polymerase chain reaction, or pcr, is a technique to make many copies of a specific dna region in vitro (in a test tube rather than an organism) pcr relies on a thermostable dna polymerase, taq polymerase , and requires dna primers designed specifically for the dna region of interest. Ap biology: dna replication lab you will use simulations to demonstrate the structure and replication of dna in this laboratory exercise as you have studied, the genetic information for living organisms is stored in the structure of deoxyribose nucleic acid (dna.
