Summary
This study analyzed SARS-CoV-2 genetic variations in Iran, finding most mutations in key viral proteins. Tracking these genomic changes is crucial for understanding future variant introductions.
Area of Science:
- Virology
- Genomics
- Epidemiology
Background:
- Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) emerged in China and caused a global pandemic.
- Understanding viral evolution and genetic diversity is critical for public health response.
Purpose of the Study:
- To investigate nucleotide and amino acid variations in SARS-CoV-2 genomes within Iran.
- To analyze phylogenetic and evolutionary events of SARS-CoV-2 in the Iranian context.
Main Methods:
- Utilized publicly available SARS-CoV-2 genome sequences up to October 15, 2021.
- Examined genetic variations across viral genomes, focusing on key proteins.
Main Results:
- The majority of identified mutations occurred in Spike and Nucleocapsid proteins, which are vaccine targets, as well as nonstructural proteins.
- The B.4 lineage was predominant in the early stages of the pandemic in Iran.
Conclusions:
- Prevalence of specific viral populations in Iran was identified.
- Monitoring SARS-CoV-2 variations in Iran and comparing them with neighboring regions can help predict future variant introductions.

15.6K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

00:36Viral Mutations
32.7K
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...

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

02:54Evolutionary Relationships through Genome Comparisons
6.1K
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...
