Hi there!!!!!!!! :DDDD
How do I solve this?A large population of laboratory animals has been allowed to breed randomly for a number of generations. After several generations, 49% of the animals display a recessive trait (bb), the same percentage as at the beginning of the breeding program. The rest of the animals show the dominant phenotype, with heterozygotes indistinguishable from the homozygous dominants.

Answer:
The mutation could cause serious damage in the replication process.
Explanation:
The TATA box is a DNA region that indicates the point where, processes like replication can begin. The mutation of this could cause that replication never begins, and therefore, protein synthesis is stopped. This severe complication would lead the cell to death in a short amount of time, for example.

Explanation:
Cytokines are proteinaceous substances that are secreted by specific immune system cells. These belong to a category of signaling molecules that are helpful in communication between the cells of immune system and thus help to mediate and regulate immunity, inflammation and hematopoiesis. Cytokines have ability to act on three types of cells -
- The cell that secretes them
- The nearby cells
- The distant cells
These molecules bind to the receptors present on the responsive target cell and evoke a particular biological activity.
