complementary base pairing

The standard arrangement of bases in nucleotides in relation to their opposite pairing, such as thymine being paired with adenine and cytosine paired with guanine.

describes the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function, but were not present in the last common ancestor of those groups.

is the accumulation of differences between groups which can lead to the formation of new species.

Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.

Nucleic acid double helix

refers to the structure formed by double-stranded molecules of nucleic acids such as DNA and RNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure.

Changes in the genes controlling development can have major effects on the morphology of the adult organism.

is the transfer of alleles or genes from one population to another.

is the change in the frequency of a gene variant (allele) in a population due to random sampling.

gradual change model of evolution

species tend to accumulate changes fairly steadily. punctuated equilibrium: species tend to stay about the same for a while, then change very rapidly. genetic drift: minor genetic changes that add up over time

is a change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element.

is the gradual process by which biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment.

is a nitrogen-containing organic molecule having the chemical properties of a base.

Mating that has not occurred due to chance, and therefore has had human interference.

Punctuated equilibrium

is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis.

is the evolutionary process by which new biological species arise.

Sugar-phosphate backbone

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA.

Term	Definition
complementary base pairing	The standard arrangement of bases in nucleotides in relation to their opposite pairing, such as thymine being paired with adenine and cytosine paired with guanine.
Convergent evolution	describes the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function, but were not present in the last common ancestor of those groups.
Divergent evolution	is the accumulation of differences between groups which can lead to the formation of new species.
DNA	Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.
Nucleic acid double helix	refers to the structure formed by double-stranded molecules of nucleic acids such as DNA and RNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure.
evolutionary change	Changes in the genes controlling development can have major effects on the morphology of the adult organism.
Gene flow	is the transfer of alleles or genes from one population to another.
Genetic drift	is the change in the frequency of a gene variant (allele) in a population due to random sampling.
gradual change model of evolution	species tend to accumulate changes fairly steadily. punctuated equilibrium: species tend to stay about the same for a while, then change very rapidly. genetic drift: minor genetic changes that add up over time
Mutation	is a change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element.
Natural selection	is the gradual process by which biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment.
Nitrogenous base	is a nitrogen-containing organic molecule having the chemical properties of a base.
Non Random Mating	Mating that has not occurred due to chance, and therefore has had human interference.
Punctuated equilibrium	is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis.
Speciation	is the evolutionary process by which new biological species arise.
Sugar-phosphate backbone	The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA.
