The Five Types Of Species Interactions Competition Competition is a common interaction among many organisms.1. Competition is described as a relationship in which different individuals or populations attempt to use the same limited resource.s time passes, species may also coevolve, where a species may evolve certain adaptations that reduce the harm of or can benefit the relationship, such as chameleons which have evolved the ability to change color and blend into their environment, which they also use as a source of communication.
Jan 3, 2015. DNA replicates by the semiconservative model of replication. This model states that during replication of double stranded DNA, the two strands separate and each separate strand is then used as a template to make a new strand.
Before replication can take place, an enzyme called helicase unwinds the DNA molecule from its tightly woven form, in the process breaking the hydrogen bonds between the nucleotide bases. This opens up or unzips the double-stranded DNA to give two single strands of DNA that can be used as templates for replication.
