Imagine that a eukaryotic cell carries a mutation that causes the poly(a) tail to rarely be added to the primary transcripts. The result of such a mutation will be the primary transcript would likely be less stable, and its transport from the nucleus to the cytoplasm would be affected.
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
While most mutations are benign, some can be detrimental. A dangerous mutation may lead to a cancerous condition or possibly a genetic problem. Chromosome mutations are yet another type of mutation. The tiny, thread-like structures known as chromosomes, which are found in the cell nucleus, carry genes.
Genetic mutations, which occur as your cells divide and generate duplicates of themselves, are modifications to your DNA sequence. Your DNA teaches your body how to develop and work. Genetic changes may result in diseases like cancer or, in the long run, may enable people to adapt to their environment more successfully.

In general, the process responsible for the growth and repair of human tissue is the healing process, which takes place in three phases.
1. inflammatory response. Injured tissues release chemicals that draw resources to the area, alert the body that damage has occurred and inhibit function to prevent further injury.
2. Repair phase. Once injured area is walled off and debris removed, construction to replace or repair injured tissue begins. New blood vessels grow in the injured area maximizing transport within tissue.
3. Remodeling phase. Construction of permanent tissue , typically strong scar tissue made from dense network of collagen fibers.
Looking at it from cell level, the process of mitosis is actually taking place during healing.
Mitosis is used for growth and repair and produces diploid cells identical to each other and to the parent cell.
New cells are needed throughout life. These are for growth and replacement of damaged or worn out tissue. The body obtains such through the process of mitosis.
The correct answer is bacteria. Bacteria abundant in soil is the main source of its organic matter. This is because bacteria release energy in their systems which causes the soil to be more fertile and more capable of sustaining plant material. Without bacteria general processes of soil formation will not be possible.
Answer:
Animals use specific strategies to attract males/females in their species because for the mating process to happen, the animals must be attracted to one another so that they can continue with the certain circle of life.
