A process defining organisms that grow and adapt to stimuli while maintaining a state of organization and energy production and being capable of reproduction.
× 33
The exchange of gases across organs that facilitate transport of the gases to and from the cells of the organism.
× 33
The study of parasites, their hosts, and the relationship between them.
× 33
Often circular segments of DNA that can replicate outside of the chromosomes. Generally found in bacteria.
× 33
the process of protein synthesis. The information encoded in the mRNA is translated into an amino acid sequence through the joint activity of tRNAs and ribosomes.
× 32
Cells which have not fully differentiated yet, i.e. with the potential to develop into other kinds of cells through asymmetric cell division.
× 31
Single nucleotide polymorphisms, or SNPs, are differences between two sequences of DNA at one individual nucleotide location.
× 31
Questions relating to the binding of proteins to each other and other molecules.
× 30
The concepts of mate choice and competition over eligible members of the opposite sex in animals, including humans.
× 30
The eukaryotic process characterized by replication of nuclear DNA and formation of a second identical nucleus. Separate from cytokinesis.

Adaptation refers to both the current state of being adapted and to the dynamic evolutionary process that leads to the adaptation.
× 29 × 29
produced during transcription before it leaves the nucleus to be be translated by a ribosome. This produces a sequence of nucleic acids for which mRNA is considered the template.

× 29
A region of repeating DNA at the end of a chromosome that protects the chromosome from decaying.
× 29
