Basic Biology Genetic diversity describes the genetic differences seen among members of a population. What this means that that every individual on the planet is different from one another in some way. This is because we have either high genetic diversity‚ or a low genetic diversity‚ which is seen through the size of the gene pool from which we came. If we happen to live in a gene pool that has a high concentration of genetic diversity‚ then we are more like to have many different genetic combinations

The function of a capsid‚ in virus biology‚ is to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic

Before watching the film I did not think biology had anything to do with racism. I believe scientist tried to prove that race was biological in order to justify the actions against the non-white race. I had never really thought about where race had come from but was surprised‚ but not hard to believe‚ to hear in the film that race was created by humans to describe social and cultural differences. Knowing that race is not biological will not eliminate racisms today. Those that are racist today
