Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...

Multi-species Conserved Sequences

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...

Evolution of Microbial Genome

Evolution of Microbial Genome

Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.

Retroviruses

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Human Virome

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...

Summary

Human parechoviruses (HPeVs), common pathogens, show genetic diversity driven by recombination. Conserved RNA structures in coding regions are crucial for HPeV replication.

Background:

Human parechoviruses (HPeVs) are widespread pathogens with over 90% seroprevalence in adults.
Recent research has expanded the known types of HPeV to eight.
Analysis of HPeV genomes provides insights into viral evolution and diversity.

Observation:

Complete genome analysis of PicoBank/HPeV1/a and VP1/3D protein sequences of PicoBank/HPeV6/a from the same individual.
PicoBank/HPeV1/a shows close relation to recent HPeV1 isolates, differing from the older Harris prototype.
Increasing availability of HPeV sequences facilitates detailed viral analysis.

Findings:

Recombination is confirmed as a significant factor in generating HPeV diversity.
Unexpected codon conservation was observed in a portion of the 3D-encoding region.
This conservation is partly explained by a conserved predicted RNA secondary structure domain.

Implications:

RNA secondary structure domains within coding regions are vital for picornavirus replication.
These findings contribute to understanding the complex mechanisms of HPeV replication and evolution.
The study highlights the importance of structural elements in viral genome function beyond known cis-acting elements.
