Answer: synthesize a pre-rRNA 45S (35S in yeast), which matures and will form the major RNA sections of the ribosome. RNA polymerase II synthesizes precursors of mRNAs and most snRNA and microRNAs. RNA polymerase III synthesizes tRNAs, rRNA 5S and other small RNAs found in the nucleus and cytosol.
Explanation:
Do whatever she feels and I would support her in anyway or any road she takes.
Answer:
The DNA strands are not free in the nucleus, but forming a compact structure called chromatin along special proteins, known as histones. The chromatin structure has an important role in gene expression, as the level of compaction and the histone modification act as signals for the transcription machinery
In order to be transcribed, different areas in the genome need to unfold from the histone proteins, so the RNA polymerase can access the DNA.
That means, <u>that DNA sequences that transcribe at high rate, are more often unfold from the histones, and more exposed to other proteins to bind them. Particularly, those areas are more sensitive to the attack of endonucleases, such as DNAse I.</u>
As a consequence, an assay of DNAse I digestion can be used to identify highly sensitive or resistant to DNAse cleavage areas in the genome, and therefore serve as an insight to which sequences are more and less transcriptionally active.
Answer:
evacuate all wildlife from the bay
Explanation:
Algal bloom is a term used to describe the excessive growth of algae species in a water body. This excessive growth or proliferation is as a result of the exposure to nutrient in form of pollutants, a process called Eutrophication.
However, the presence of an algal bloom indicates the pollution of that water body, which will result in the degradation of the pollutants by bacteria. As bacteria acts on the pollutants in the water body, they excessively use the dissolved oxygen of the water body, hence, drastically reducing the oxygen levels of the water. This possess a great threat to aerobic wildlife in the water, which could die as a result of suffocation or anorexia.
Hence, the most important thing to do in a case of noticing an algal bloom in a bay is to evacuate all wildlife from the bay in order to prevent mass death.
