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 ...
Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand. [ 7 ]
The term is commonly used to describe strands of DNA or RNA which are actively undergoing synthesis during replication or transcription, respectively, or sometimes a complete, fully transcribed RNA molecule before any alterations have been made (e.g. polyadenylation or RNA editing), or a peptide chain actively undergoing translation by a ribosome.

Critics of neoconservatism have used the term to describe foreign policy and war hawks who support aggressive militarism or neocolonialism. Historically speaking, the term neoconservative refers to Americans who moved from the anti-Stalinist left to conservatism during the 1960s and 1970s. [5]
Site-specific recombination, also known as conservative site-specific recombination, is a type of genetic recombination in which DNA strand exchange takes place between segments possessing at least a certain degree of sequence homology.
A multiple sequence alignment of five mammalian histone H1 proteins Sequences are the amino acids for residues 120-180 of the proteins. Residues that are conserved across all sequences are highlighted in grey.
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.
