In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.

Ex Input:
Biochemical experiments and genome sequencing have shown that , despite the prokaryotic cell and genome organization , basal transcriptional elements of members of the domain Archaea ( i . e . , TATA box - like sequences , RNA polymerase , and transcription factors TBP , TFIIB , and TFIIS ) are of the eukaryotic type .

Ex Output:
RNA polymerase

Ex Input:
The major promoter element of the Xenopus laevis 5S RNA gene is located within the transcribed region of the gene and forms the binding site for the transcription initiation factor TFIIIA .

Ex Output:
5S RNA

Ex Input:
This activity creates a 4 - bp staggered cut with 3 ' OH overhangs within a specific sequence of the 21S rRNA gene of omega - strains .

Ex Output:
21S rRNA gene
