What is genetic variation? Genetic variation is the differences that are found in the DNA sequences among individuals of the same species. It’s what makes every organism a bit different from others even they belong to same population. Inside populations, variation is mostly caused by mutations, recombination / crossing over (during meiosis), and sometimes by … Read more
What is Artificial Selection? Artificial selection is a process by which humans are intentionally choosing certain organisms / traits for reproduction, it has been used for centuries actually even before the mechanism of genes was understood properly.

DNA replication is the process by which genetic material is copied before cell division happens, it’s considered essential for inheritance. Among different models, the main ones observed are Theta model, Rolling Circle model, and Linear DNA replication. Each model are used by different organisms or DNA types (like plasmids, viruses, or eukaryotic chromosomes). The three … Read more

An codon chart is presented as a compact key, that maps three-nucleotide codons to amino acids, and it is usually shown as a table or circular map. In the chart, each codon is represented by three bases (A, U, G, C) and is read in the 5’→3’ direction, misreading the direction will alter meaning. Sixty-four … Read more

Although Aspergillus flavus is widely distributed in soil and decaying plant material, it is most often associated with warm, humid agricultural environments where crops are produced. Aspergillus flavus is classified as a filamentous fungus within the genus Aspergillus. When stored grains (maize/peanuts,cottonseed) are exposed to moisture and heat, contamination is caused frequently by this fungus … Read more
