Answer:
Sigma factor is the name of the protein and it helps RNA polymerase to recognize promoter.
Explanation:
RNA polymerase is the enzyme which helps in the transcription of DNA duplex. In bacteria, a protein called sigma factor is present in RNA polymerase which is responsible for the initiation of transcription.
The sigma factors gives the ability to RNA polymerase to recognize the promoter sequence. If the sigma factor is not present in RNA polymerase than this enzyme can not distinguish between promotor and other sequences.
So the sigma factor increases the affinity of RNA polymerase towards promoter and helps in initiation of the transcription. Sigma factor gets released from the core enzyme when the chain reaches 8-9 bases.
The environmental effects of harmful practices on private property are not essentially restricted to private property, it can also affect public property. Water polluted on private property might stream down into a local river or an aquifer used for public purposes like drinking water or for recreational parks (swimming pools). Landowners who slaughter travelling animals on their property are putting an end to creatures that are part of a bigger ecosystem; the loss of these animals will affect all the ecosystems along the migration route.
One major function of a monosaccharide<span> is its use for energy within a living organism. Glucose is a commonly known carbohydrate that is metabolized within cells to create fuel. In the presence of oxygen, glucose breaks down into carbon dioxide and water, and energy is released as a byproduct.</span>
Answer:
The marine industries affected the marine life and ocean water in many ways. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH drops. In the past two hundred years alone, ocean water has become 30 percent more acidic and faster than any known change in ocean chemistry in the last million years.
Hope it helps!
