91Polyadenylation — Typical structure of a mature eukaryotic mRNA Polyadenylation is the addition of a poly(A) tail to an RNA molecule. The poly(A) tail consists of multiple adenosine monophosphates; in other words, it is a stretch of RNA that has only adenine bases …
92Operon — A typical operon In genetics, an operon is a functioning unit of genomic DNA containing a cluster of genes under the control of a single regulatory signal or promoter.[1][2] The genes are tr …
93Alternative splicing — produces two protein isoforms. Alternative splicing (or differential splicing) is a process by which the exons of the RNA produced by transcription of a gene (a primary gene transcript or pre mRNA) are reconnected in multiple ways during RNA… …
94Gene silencing — is a general term describing epigenetic processes of gene regulation. The term gene silencing is generally used to describe the switching off of a gene by a mechanism other than genetic modification. That is, a gene which would be expressed… …
95Homologous recombination — Figure 1. During meiosis, homologous recombination can produce new combinations of genes as shown here between similar but not identical copies of human chromosome 1. Homologous recombination is a type of genetic recombination in which nucleotide …

97nucleic acid — /nooh klee ik, klay , nyooh /, Biochem. any of a group of long, linear macromolecules, either DNA or various types of RNA, that carry genetic information directing all cellular functions: composed of linked nucleotides. [1890 95; NUCLE(US) + IC;… …
98Mdm2 — p53 binding protein homolog (mouse) Solution structure of Mdm2. [1] …
99HHV Infected Cell Polypeptide 0 (ICP0) — Human Herpes Virus (HHV) Infected Cell Polypeptide 0 (ICP0) is a protein, encoded by the DNA of herpes viruses. It is produced by herpes viruses during the earliest stage of infection, when the virus has recently entered the host cell; this stage …
100Secreted frizzled-related protein 1 — The Secreted frizzled related protein (SFRP) family consists of five secreted glycoproteins in humans ( 300 amino acids in length) that act as extracellular signaling ligands. Each SFRP contains a cysteine rich domain (CRD) that shares 30 50%… …
