The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.
A polar climate only has 2 subtypes. These are tundra climate (ET) and the ice cap climate (EF).
Both climate lack of warm summers. The average temperature is less than 10 degree Celsius. In a tundra climate, they experience at least a month of having above zero temperature compare to an ice cap which is always below zero.
CONTRACTILE RINGS are a contractile ring of actin micro filaments that eventually results in the division of the cytoplasm.
The contractile ring are usually formed during the early anaphase phase of the cell division cycle. During the cellular cleavage, the contractile rings tighten around the cytoplasm of the cell until it is pinched into two daughter cells.
Answer:
Diazepam.
Explanation:
Taxonomy is the field of the biology that mainly concerns with the classification, nomenclature, identification an systematic of the organisms. Different categories are isoltype, holotype, haplotype and prototype.
Pototype may be defined as a type of model used in the cognitive science for the graded categorization. In the prototype some species is considered more central than the other species. In the given question, the diazepam can be used as a prototype.
Thus, the answer is diazepam.
