How can you use “luca” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The first, "introns-early", posits that introns were present in most, if not all, protein-coding genes in the last universal common ancestor (LUCA) and have subsequently been lost in the archaeal and bacterial domains due to strong selection for compact genomes.

  • In contrast, the DPBBs detected in DDRP subunits are universally present in all modern life forms and hence are traceable to LUCA.

  • Although the sequences of the Zn-ribbons of bacterial and archaeo-eukaryotic DDRP subunits have diverged considerably, their similar location in the orthologous polypeptides from different kingdoms suggests that β' subunit of LUCA already contained a Zn-ribbon.

  • Hence, considerable diversity of protein domains appears to have emerged prior to the "crystallization" [ 95 ] of a transcription machinery similar to the one that operates in modern cells and probably had been already in place in LUCA [ 96 ] . Similar conclusions regarding the early stages of protein domain evolution have been reached previously as a result of evolutionary analysis of proteins involved in translation, such as aminoacyl-tRNA synthetases and GTPases: substantial diversification of protein domains had occurred prior to the "crystallization" of elaborate, modern-type translation machinery [ 66 97 ] .

  • Luca della Robbia’s subdued glazed ceramic roundels depict the 12 Apostles and Four Evangelists.
