A BIRD´S-EYE VIEW OF CHROMOSOMES DURING MEIOTIC PROPHASE I [PDF]

BAG. Journal of Basic and Applied Genetics, 2022
The present review aims to summarize the research carried out in relation to meiosis in birds, especially by observing the protein axes of the chromosomes in prophase I of meiosis. This line of research, initially developed in Argentina, has provided key

Crossover interference mechanism: New lessons from plants

Frontiers in Cell and Developmental Biology, 2023
Plants are the source of our understanding of several fundamental biological principles. It is well known that Gregor Mendel discovered the laws of Genetics in peas and that maize was used for the discovery of transposons by Barbara McClintock.

Effect of Female Age on Crossing Over Frequency in Drosophila melanogaster Crosses N x bcl and N x ym and Their Reciprocals

Biology, Medicine & Natural Product Chemistry, 2023
Crossing over is the occurrence of disconnection and reconnection followed by a reciprocal exchange between the two chromatids in a bivalent form. The crossing event will produce parental type and recombinant type.

Cytological Analysis of Crossover Frequency and Distribution in Male Meiosis of Cardueline Finches (Fringillidae, Aves)

Animals, 2023
Meiotic recombination is an important source of genetic diversity. Using immunolocalization of several meiotic proteins at the spreads of male pachytene cells, we estimated the number of recombination nodules per cell and their distribution along the ...

SUMO is a pervasive regulator of meiosis

eLife, 2021
Protein modification by SUMO helps orchestrate the elaborate events of meiosis to faithfully produce haploid gametes. To date, only a handful of meiotic SUMO targets have been identified.

The Formation of Bivalents and the Control of Plant Meiotic Recombination

Frontiers in Plant Science, 2021
During the first meiotic division, the segregation of homologous chromosomes depends on the physical association of the recombined homologous DNA molecules.

Rmi1 stimulates decatenation of double Holliday junctions during dissolution by Sgs1-Top3 [PDF]

, 2010
double Holliday junction (dHJ) is a central intermediate of homologous recombination that can be processed to yield crossover or non-crossover recombination products. To preserve genomic integrity, cells possess mechanisms to avoid crossing over. We show
