Answer:

Extra nucleotides. Extra nucleotides

Explanation:

When the transcription of a gene ends, a poly(A) tail is added at the end 3' of the pre messenger RNA (mRNA)  The poly(A) tail  is a long sequence of several hundred adenine nucleotides. The polyadenylation is part of the the maturation process of the mRNA for translation. The poly(A) tail is important for stability of mRNA; eventually it is shortened and, when it is short enough, is enzymatically degraded.

Why is the modeling of ozone layer depletion more accepted than modeling for global warming?
tekilochka [14]

Ozone layer depletion is not a major cause of climate change. Global warming will be more significant contributor of climate change on earth.

<h3>What is ozone layer depletion and global warming?</h3>

Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when ozone molecules interact with atmospheric chlorine and bromine atoms and break down. One chlorine molecule is capable of destroying one ozone molecule. It is not produced as quickly as it is destroyed.

The phenomenon of rising average air temperatures close to the surface of the Earth over the previous one to two centuries is known as global warming. This change has disturbed the climatic pattern of the earth. The burning of fossil fuels, logging of forests, and raising of livestock all have a rising impact on the climate and temperature of the planet. This increases the greenhouse effect and causes global warming by adding a significant amount of greenhouse gases to those that are already present in the atmosphere.

Ozone layer depletion is more acceptable than global warming because global warming is more responsible for the climate change in the earth, it traps huge amount of gases which rise the earth's temperature. Climate change may not primarily be caused by the ozone hole. Although a larger ozone hole does not contribute to global warming, the presence of ozone, a greenhouse gas, has a warming impact. The ozone hole itself has a minor cooling effect (about 2 % of the warming effect of greenhouses gases) because ozone in the stratosphere absorbs heat radiated to space by gases in a lower layer of Earth’s atmosphere. A small amount of heat can escape from that area into space as a result of the loss of ozone.
