Question

Where can early recombination nodules be found?

Answer 1

Hint: A nodule could be a growth of abnormal tissue. Nodules can develop slightly below the skin. they will also develop in deeper skin tissues or internal organs. Dermatologists use nodules as a general term to explain any lump underneath the skin that's a minimum of 1 centimeter in size.

Complete answer:
Recombination nodules are multicomponent proteinaceous ellipsoids found in association with the synaptonemal complex during prophase I of meiosis. Numerous early RNs are observed during zygotene, and they could also be involved in homologous synapsis and early events in recombination.
Recombination nodules (RNs) are multicomponent proteinaceous ellipsoids found in association with the synaptonemal complex (SC) during prophase I of meiosis. Numerous early RNs (ENs) are observed during zygotene, and they are also involved in homologous synapsis and early events in recombination. Fewer late RNs (LNs) are observed during pachytene, and they occur at crossover sites.
Recombination Nodules is the site where crossover takes place because of which the four chromatids of every chromosome become clearly distinct and appear as tetrads. Chiasmata on the opposite hand is created during the diplotene or diplonema stage of prophase.
Large protein complexes on the synaptonemal complex between two synapsed homologous chromosomes. There's evidence that genetic recombination events in meiosis are catalyzed by these recombination nodules.

Note:
There are three forms of recombination; Radiative, Defect, and Auger. Auger and Defect recombination dominate in silicon-based solar cells. Among other factors, recombination is related to the lifetime of the fabric, and thus of the cell.
