DNA viruses, as the name implies have DNA as their genetic material. On the other hand, RNA viruses have RNA as their genetic material. RNA... View Article
Urine does contain DNA, but it might not be feasible for extraction as the amount of DNA present is small when compared to blood or saliva.... View Article
If two viruses (from different parent strains) infect the same host cell and interact during the replication process. The resultant virus... View Article
Pandoravirus salinus is the largest virus discovered to date. It has a genome length of 2473870, which corresponds to around 2500 genes. It has a... View Article
A virus cannot be classified as a living organism as it does not meet all the required criteria for life. However, scientists have identified... View Article
Usually, viruses are no longer than 17 to 300 nm. For instance, the SARS-CoV-2 virions range between 50 nm to 200 nm in diameters. In comparison,... View Article
The Central Dogma states that the flow of genetic information is from DNA to RNA to protein in all biological cells. However, retroviruses are... View Article
Some primitive viruses, retroviruses and even prions do not follow the Central Dogma. However, these entities are not exactly classified as... View Article
Viruses undergo natural selection similar to cell-based life forms. Hence, some of them might evolve rapidly. Furthermore, viruses can evolve... View Article
Yes, wildlife sanctuaries are a type of in-situ conservation. In-situ conservation conserves and protects the whole ecosystem. Animals are... View Article
Beta diversity tells about the change in the diversity of two communities. It tells about the number of species that are different in both the... View Article
Humans affect genetic diversity by destructing habitats, climate change due to human activities, pollution, artificial selection (agriculture,... View Article
Natural selection is the most important force of evolution. Other forces of evolution are mutation, gene flow and genetic drift. Further... View Article
Gene flow and natural selection are the two central evolutionary forces with opposing effects. Gene flow distributes genetic diversity and... View Article
Gene flow counteracts natural selection by changing gene frequencies that occurred due to natural selection. Natural selection leads to an... View Article
Gene frequency or allele frequency is the relative frequency of an allele in a population. It tells about the percentage of occurrence of an... View Article
Assisted gene flow refers to the intentional migration of genes to a different population. It is done to increase the presence of desired genes... View Article
Gene flow is the migration of genes from one population to another and causes variation in that population, whereas mutation causes a change in... View Article
Gene flow can be measured by comparing allele frequencies of populations. If the two populations show more differences in their gene pool, it... View Article
