Explanation:

Lampbrush Chromosome

The lampbrush chromosomes have the lateral loops that extrude from the chromomeres at certain positions. Chromomeres are the beads that appear at the meiosis stage in which the chromosomes resemble a series of beads on a string. The loop is an extruded segment of DNA that is being actively transcribed. Because of their distinctive chromomere-loop organization and intense transcriptional activity of lateral loops, the lampbrush chromosomes have served as a powerful system for exploring the general principles of chromosome organization and function.

Oocytes of all urodele amphibians contain spectacular diplotene prophase chromosomes in which DNA is decondensed into several thousand lateral loop pairs. These lateral loop pairs are displayed along the chromosome axis. Lateral loops, which are responsible for the typical aspect of lampbrush chromosomes, represent regions of intense RNA synthesis, and the nascent RNA transcripts associate with proteins to form a RNA matrix
