Question | Answer |
---|---|
Complementary Base Pairing | The manner in which nitrogenous bases align with each other |
Convergent Evolution | when different organisms undergo similar adaptations. |
Divergent Evolution | when one species undergoes different adaptations because of isolated environments. |
Deoxyribonucleic acid (DNA) | the carrier of genetic information for nearly all living organisms |
Double Helix | a pair of helices that are intertwined on a common axis. DNA has this shape. |
Evolutionary Change | A gradual change in the characteristics of a population. |
Gene Flow | The transfer of alleles form one population to another. |
Genetic Drift | Random change in allele frequency. |
Gradual Change Model | The theory in which species adapt over long periods of time |
mutation | The changing is the structure of a gene. |
natural selection | The process in which the fittest organisms survive and reproduce. |
nitrogenous base | A nitrogen molecule containing the same properties as a base. They are the building blocks of DNA and RNA |
Non Random Mating | When the probability that two individuals in a population will mate is not the same for all possible pairs of individuals. |
Punctuated Equilibrium Model | A theory in evolutionary biology which proposes that once species appear in the fossil record they will become stable. |
speciation | The evolutionary process in which new species arise. |
Sugar Phosphate Backbone | The substance which forms the structural framework of DNA and RNA |
