Semiconservative replication describes the mechanism of DNA replication in all known cells. DNA replication occurs on multiple origins of replication along the DNA template strands. As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi ...
Examples of highly conserved sequences include the RNA components of ribosomes present in all domains of life, the homeobox sequences widespread amongst eukaryotes, and the tmRNA in bacteria. The study of sequence conservation overlaps with the fields of genomics, proteomics, evolutionary biology, phylogenetics, bioinformatics and mathematics.
Nepantla is a concept used in Chicano and Latino anthropology, social commentary, criticism, literature and art. It represents a concept of "in-between-ness." [1] Nepantla is a Nahuatl word which means "in the middle of it" or "middle." [2] It may refer specifically to the space between two figurative or literal bodies of water. [3]

Bioconservatives' reluctance to acknowledge the fragility of their ...
The central dogma of molecular biology deals with the flow of genetic information within a biological system. It is often stated as "DNA makes RNA, and RNA makes protein", [1] although this is not its original meaning.
The anthroposphere refers to that part of the Earth system that is made or modified by humans for use in human activities and human habitats.The term has been suggested for inclusion as one of the Earth's spheres, [1] while others use the related term technosphere. [2]
