Tandem gene arrays (TGAs) in yeasts are dynamic genomic regions prone to rearrangements. These structures facilitate the emergence of new genes, enabling rapid adaptation to environmental changes.
Area of Science:
- Genetics
- Genomics
- Yeast Biology
Background:
- Tandem gene arrays (TGAs) are specialized chromosomal structures.
- Their role in hemiascomycete yeasts requires further investigation.
Purpose of the Study:
- To provide an overview of TGAs in hemiascomycete yeasts.
- To analyze structural, functional, and evolutionary aspects of TGAs.
- To discuss the genomic instability of TGAs.
Main Methods:
- In silico genomic analysis.
- In vivo experimental approaches.
Main Results:
- TGAs are dynamic genomic regions.
- TGAs are sites of chromosomal rearrangement events.
- TGAs contribute to the generation of new genes.
Conclusions:
- TGAs are generally unstable and prone to rearrangements.
- TGAs play a role in rapid cellular adaptation to environmental demands.

LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...
