Flashcards in DNA Deck (14)
A pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule.
Are organic molecules consisting of a nucleoside and a phosphate.
A sugar derived from ribose by replacing a hydroxyl group with hydrogen.
Chargaff's rules state that DNA from any cell of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases
is the biological process of producing two identical replicas of DNA from one original DNA molecule.
is a structure that forms within the long helical DNA during DNA replication
are a class of enzymes vital to all organisms.
is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA.
is used in key metabolic processes for all steps of protein synthesis in all living cells and carries the genetic information of many viruses.
is the first of several steps of DNA based gene expression in which a particular segment of DNA is copied into RNA
is the process of translating the sequence of a messenger RNA
plays a vital role in human biology, specifically in a process known as protein synthesis
is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins.
