PPT-DNA and RNA Replication

Unit 6 Something to think about When a species reproduces there is genetic continuity maintained from one generation to the next WHAT is responsible for this continuity HOW does this continuity happen. Chapters 16 and 17. Before the end of the semester we will be covering…. Historical DNA experiments. Structure of DNA/RNA. DNA Replication. Protein Synthesis (Transcription and Translation). Mutations. Learning Objectives. What happens during DNA replication?. How is a new polynucleotide strand formed?. Why is DNA replication known as ‘semi-conservative’?. Putting What We’ve Learnt So Far In To Context.... Semiconservative vs. Conservative. DNA Polymerase. RNA Primase. Okazaki Fragments. Replication Errors. TeachWithFergy . Preview File. .

One of the benefits of the double stranded DNA structure is that it lends itself to repair, when structural damage or replication errors occur. Several kinds of chemical change may cause damage to DNA:. . Understanding DNA structure and replication is a prerequisite for understanding/using the principal tools of molecular biology . R. R. 0.

Griffith finds a ‘transforming principle.’ . Griffith experimented with the bacteria that cause pneumonia.. He used two forms: the S form (deadly) and the R form (not deadly).. A transforming material passed from dead S bacteria to live R bacteria, making them deadly.. replicate (copy) DNA?. Growth. Reproduction. Repair. Where do we start?.
