- Polymerase Chain Reaction (pcr)
There are three stages to PCR: denaturation, heating, and extension. In the first stage, denaturation, the reaction tube in the thermal cycler is heated to 95 degrees Celsius. The high heat denatures DNA by breaking the hydrogen bonds; the double helix...
- Q: Compare And Contrast Dna Replication And Transcription
Similarities: Both processes occur in the nucleus. Both processes also involve specific complementary base pairing. Both processes involving the unwinding of the double helix DNA. Both processes involve forming of hydrogen bonds between the original DNA...
- Transcription
Each gene contains a specific nucleotide sequence called the promoter region and it contains the initiation site, where proteins, called transcription factors, and RNA polymerase enzyme recognize and bind to. The enzyme-DNA-protein complex then causes...
- Dna Is A Double Helix
KEY TERMS: Base pairing describes the specific (complementary) interactions of adenine with thymine or of guanine with cytosine in a DNA double helix (thymine is replaced by uracil in double helical RNA). Complementary base pairs are defined by the pairing...

Definition
A DNA double helix formed by two strands from different individuals or different giving some base pairs not complementary (helix loops).
