• DNA Synthesis

  A chemical equation that describes the synthesis of DNA can be: (DNA)n + dNTPs + DNAPol <--------> (DNA)n+1 + PPi (2) DNAPol = DNA polymerase (DNA)n = template DNA (DNA)n+1 = growing new DNA strand PPi = two pyrophosphate

• DNA Repair Mechanisms

  550108 DNA Repair Mechanisms What is DNA repair? What are the mechanisms of DNA repair? What is DNA stability? DNA is the genetic information in each living cell. It is responsible for how we look and is essential to life itself.

• DNA evidence

  Every individuals has DNA in their cells. DNA is present in the nucleus of every cells in your body. The skin, the blood, hair, tears, saliva, sweat, sperms, eggs, and all bodily fluid contain DNA. DNA is present in every genes in your body.

• Discuss different models for DNA replication that were considered by early researchers.

  DNA replication starts with unwinding of the DNA. Proteins called helicases unwind the DNA at particular locations in the DNA called replication origins. These are just locations were DNA is unwound for replication.

• Southern Blot Technique

  (a) Cutting the DNA with restriction enzyme, blotting the DNA, electrophoresis of DNA, hybridizing the DNA with probe. (b) Cutting DNA with restriction enzyme, electrophoresis of DNA, blotting the DNA, hybridizing the DNA with probe.

• DNA Replication Models

  They want to observe whether the new DNA was the same as the old DNA. To differentiate between the heavy labeled DNA and the light labeled DNA. 4.

• Restriction Enzyme DNA

  DNA.

• Radiolabeling to track DNA strands during replication.

  How many DNA strands are radio-labeled? Are both radio-labeled strands in the same DNA molecule? Each time the DNA molecule replicates, the result will be two new DNA molecules, as each of the two strands is copied.

• Isolating DNA
