Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Homologous Recombination

Homologous Recombination

The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

Long-patch Base Excision Repair

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Mass Spectrometry: Molecular Fragmentation Overview

Mass Spectrometry: Molecular Fragmentation Overview

The ionization of a molecule into a molecular ion inside the mass spectrometer causes instability in the molecule's structure due to the loss of an electron. This eventually leads to the fragmentation or breaking of some bonds in the molecule. The fragmentation occurs predominantly at specific bonds to yield relatively stable fragments.
One type of fragmentation pattern is the cleavage of a single bond in the molecular ion. The cleavage leads to a radical and a cation. The cleavage can...

Restarting Stalled Replication Forks

Restarting Stalled Replication Forks

DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart,...

Background:

Transfer RNAs (tRNAs) possess unique structures essential for mRNA decoding via anticodon trinucleotides.
tRNAs interact with aminoacyl-tRNA synthetases and ribosomes through specific 3D shape and sequence signatures.
Beyond translation, tRNAs function as signaling molecules interacting with other RNAs and proteins.

Purpose of the Study:

To explore the concept of tRNA fragmentation as a creative evolutionary process generating functional molecules.
To investigate the biological roles and interaction potentials of tRNA-derived small RNAs (tsRNAs).
To highlight the significance of tRNA 'renovatio' in biological complexity and pharmaceutical applications.

Main Methods:

Utilizing emerging methods to determine full tRNA/tsRNA sequences and modifications.
Employing techniques to study RNA structures and their three-dimensional arrangements.
Integrating Artificial Intelligence (AI)-powered predictions for comprehensive analysis.

Main Results:

tRNA fragmentation is an 'act of recreation,' producing specific tsRNAs, not random degradation.
tsRNAs exhibit unexpected biological functions leveraging their linear sequences and novel 3D structures.
These findings exemplify tRNA 'renovatio,' a renewal and rebirth of tRNA molecules.

Conclusions:

Advancements in sequencing, structural biology, and AI will enable detailed investigation of tsRNAs.
Understanding tRNA fragmentation products and their interactions is key to uncovering new biological functions.
This research opens new avenues for understanding biological complexity and advancing pharmaceutical engineering.
