## TL;DR

This paper presents the full DNA sequence of a circular genetic element in the organism Naegleria pringsheimi.

## Contribution

The complete sequence of the CERE in Naegleria pringsheimi (strain Singh) is reported for the first time.

## Key findings

- The CERE contains the DNA encoding ribosomal RNA.
- The sequence is closed and circular, as found in the nucleolus.

## Abstract

The DNA encoding the ribosomal RNA in Naegleria is encoded on closed circular extrachromosomal ribosomal DNA-containing elements (CERE) in the nucleolus. In this report, we describe the sequence of the CERE of Naegleria pringsheimi De Jonckheere (strain Singh).
