 Context examples 

During NER in eukaryotes, shape irregularities are detected by protein complexes that slide along the DNA molecule and induce cuts on each side of a lesion several nucleotides away.

(Nucleotide Excision Repair, NCI Thesaurus)

Helix-turn-helix motifs were originally identified in bacterial proteins but have since been found in hundreds of DNA-BINDING PROTEINS from both eukaryotes and prokaryotes.

(Helix-Turn-Helix Motif, NLM, Medical Subject Headings)

Originally identified in bacterial proteins and found in many DNA-binding proteins from both eukaryotes and prokaryotes.

(Helix-Turn-Helix Motif, NCI Thesaurus)

The best known among them are a family of six structurally related proteins, MCM2-7, which are evolutionally conserved in all eukaryotes.

(MCM Protein, NCI Thesaurus)

The term microorganism may refer to a prokaryote or eukaryote, and may be a unicellular or multicellular organism.

(Microorganism, NCI Thesaurus)

A recent study shows that bacteria accomplish NHEJ using just two proteins (Ku and DNA ligase), whereas eukaryotes require many factors.

(Non-Homologous End-Joining Pathway, NCI Thesaurus/KEGG)

Genes from the alpha, beta and gamma tubulin families are found in all eukaryotes.

(Microtubule, NCI Thesaurus/LocusLink)

Hundreds of GPI-anchored proteins have been identified in many eukaryotes ranging from protozoa and fungi to mammals.

(Glycosylphosphatidylinositol-Anchor Biosynthesis Pathway, NCI Thesaurus/KEGG)

During NER in eukaryotes, protein complexes detect DNA shape irregularities, induce cuts on each side of the lesion, remove the damaged fragment, and repair the helix by synthesis and ligation.

(Nucleotide Excision Repair Inhibition, NCI Thesaurus)

Initiation of DNA replication in eukaryotes is a highly conserved, multi-step process (replication licensing) designed to restrict initiation events to once per replication origin per S phase.
