Ontology: RNA, Messenger (C0035696)

Definition (NCI) A class of RNA molecule containing protein-coding information in its nucleotide sequence that can be translated into the amino acid sequence of a protein.
Definition (NCI_NCI-GLOSS) A type of RNA found in cells. Messenger RNA molecules carry the genetic information needed to make proteins. They carry the information from the DNA in the nucleus of the cell to the cytoplasm where the proteins are made.
Definition (NCI_CDISC) A class of RNA molecule containing protein-coding information in its nucleotide sequence that can be translated into the amino acid sequence of a protein.
Definition (MSH) RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Definition (CSP) RNA sequences that serve as templates for protein synthesis; eukaryotic messenger RNA is synthesized in the nucleus and must be exported to the cytoplasm for translation.

Ontology: Transfer RNA (C0035711)

Definition (NCI) A class of short adaptor RNAs that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. Each transfer RNA comprises a three-nucleotide sequence that is complementary to the triplet nucleotide coding sequence of an mRNA, conferring specificity to the amino acid being incorporated into the assembling protein.

Each transfer RNA comprises a three-nucleotide sequence that is complementary to the triplet nucleotide coding sequence of an mRNA, conferring specificity to the amino acid being incorporated into the assembling protein.
Definition (MSH) The small RNA molecules, 73-80 nucleotides long, that function during translation (TRANSLATION, GENETIC) to align AMINO ACIDS at the RIBOSOMES in a sequence determined by the mRNA (RNA, MESSENGER). There are about 30 different transfer RNAs. Each recognizes a specific CODON set on the mRNA through its own ANTICODON and as aminoacyl tRNAs (RNA, TRANSFER, AMINO ACYL), each carries a specific amino acid to the ribosome to add to the elongating peptide chains.
Definition (CSP) small ribonucleic acid molecules 73 to 93 nucleotides long, occurring in cells in about 30 varieties and functioning in translation; each variety carries a specific amino acid to a site specified by an RNA codon, binding to amino acid, ribosome, and to the codon via an anticodon region; all have numerous modified bases and extensive secondary structure.

Ontology: Transcription, Genetic (C0040649)

Definition (NCI_NCI-GLOSS) The process of synthesizing messenger RNA (mRNA) from DNA.
Definition (NCI) A genetic process in which single-stranded RNA with base sequence complementary to a region of plus strand DNA is synthesized by DNA-dependent RNA polymerases. Following the binding of RNA polymerase on DNA promoter regions, the RNA product is synthesized in a 5' to 3' direction, elongating RNA along the DNA strand as the polymerase proceeds, accompanied by unwinding and rewinding of the DNA template.
Definition (MSH) The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION.
Definition (CSP) transfer of genetic information from DNA to messenger RNA by DNA-directed RNA polymerase; includes reverse transcription and transcription of early and late genes expressed early in an organism's life cycle or during later development.

Ontology: Protein Biosynthesis (C0597295)

Definition (GO) The cellular metabolic process in which a protein is formed, using the sequence of a mature mRNA molecule to specify the sequence of amino acids in a polypeptide chain. Translation is mediated by the ribosome, and begins with the formation of a ternary complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2, which subsequently associates with the small subunit of the ribosome and an mRNA. Translation ends with the release of a polypeptide chain from the ribosome. [GOC:go_curators]
Definition (NCI) Protein synthesis is the group of processes that are involved in generation of mature protein molecules. Although protein synthesis may involve translation alone in many cases, in others, it involves also protein folding, integration of prosthetic groups, glycosylation, methylation, phosphorylation, lipidation and any other process that may be involved in maturation of the polypeptide to the biologically active form.
Definition (MSH) The biosynthesis of PEPTIDES and PROTEINS on RIBOSOMES, directed by MESSENGER RNA, via TRANSFER RNA that is charged with standard proteinogenic AMINO ACIDS.
Definition (CSP) ribosome mediated process by which polypeptide chains are synthesized, the aminoacid sequence being completely determined by the sequence of bases in a messenger RNA, which in turn is determined by the sequences of bases in the DNA of the gene from which it was transcribed.
Definition (CSP) anabolic formation of proteins in organisms or living cells; for more specific steps in the process of forming proteins, see related terms.

Ontology: DNA Replication (C0598312)

Definition (GO) The cellular metabolic process in which a cell duplicates one or more molecules of DNA. DNA replication begins when specific sequences, known as origins of replication, are recognized and bound by initiation proteins, and ends when the original DNA molecule has been completely duplicated and the copies topologically separated. The unit of replication usually corresponds to the genome of the cell, an organelle, or a virus. The template for replication can either be an existing DNA molecule or RNA. [GOC:mah]
Definition (NCI_NCI-GLOSS) The process by which a copy of the DNA in a cell is made before the cell divides.
Definition (NCI) The process by which the two strands of a DNA double helix separate, allowing each strand to act as a template for the synthesis of a complementary strand by specific base pairing. Includes autonomous but not virus replication.
Definition (NCI) DNA Synthesis is the polymeric linkage of deoxyribose moieties (with adenine, guanine, cytosine, or thymine side chains) by phosphate groups attached to their 5-prime and 3-prime sugar hydroxyls.
Definition (MSH) The process by which a DNA molecule is duplicated.
Definition (CSP) process by which a DNA molecule is duplicated in vivo, or studies of the natural process in vitro; for artificial synthesis, see NUCLEIC ACID CHEMICAL SYNTHESIS and its narrower terms.
