Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
Answer:
in my oppinion its call a
source of pergisol
Explanation:
What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.
Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.
Answer:
Explanation:
Proteins, such as RNA (ribonucleic acid) polymerase, were loaded into lane 2. TFIIB and TFIID are two forms of TFII. These proteins attach to the fragment of DNA. Furthermore, these proteins shield DNA from the DNase enzyme, which may trigger DNA to split. As a result of the above findings, we may conclude that the inserting proteins(RNA polymerase, TFIID and TR 8 proteins) cover the area between 500 and 800 bp (base pair) in the DNase I footprinting experiment.
As a consequence, the length duration is 300bp since the promoter area is about 500-800bp and is not digested by DNase after incubation of inserting proteins.
D all of these create a magnetic field. let me know if you want me to explain.
