| Nucleotides DNA consists of the nucleotide bases: Adenine (A) Cytosine (C) Guanine (G) Thymine (T)RNA consists of the nucleotide bases: Adenine (A) Cytosine (C) Guanine (G) Uracil (U) | View Page |
| Which of these nucleotide bases is present in DNA but is replaced by Uracil in RNA? | View Page |
| Factors Affecting Hybridization Because hybridization involves nucleotide bases and the separation and joining or reannealing of strands, several environmental factors can influence this process: Temperature: If the temperature is too high, the strands melt. If it is too low, they might be forced together. The pH: A pH that is too alkaline will cause the strands to separate; too acidic and they are forced together. The guanine to cytosine ratio (G:C ratio): Since this bond is stronger than the other nucleotide bonds, if the G:C ratio in the desired target strand is high, the separation process may take longer. | View Page |
