Biology
The two strands of DNA are anti parallel. Their 5' to 3' direction is in opposite direction. As the active site of the enzyme DNA polymerase III only recognizes the 3' end of a DNA nucleotide, free nucleotides can only be added in the 3' direction. Hence each of the two strands of DNA can only elongate in different directions when undergoing replication.
- 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...

Transcription in Eukaryotic Cells What is transcription? Transcription is the process that creates RNA inside a cell. It is used to develop proteins inside the cytoplasm of a cell although the actual transcription happens in the nucleus and mitochondria....

DNA Replication?DNA can copy its self over and over again in order to keep creating for the organism it is working for. This action is called DNA replication and takes place in the cell nucleus. How does DNA replication work? The molecules of DNA...

KEY TERMS:A replication fork (Growing point) is the point at which strands of parental duplex DNA are separated so that replication can proceed. A complex of proteins including DNA polymerase is found at the fork. A DNA polymerase is an enzyme that...
