Larval Forms in Protochordates The larval forms of Protochordates, along with the subphylum Cephalochordata (lancelets) and Urochordata (tunicates), are central to the clarification of the phylogeny of Chordata. The larval stages of Protochordates exhibit very typical characteristics provided within all chordates, such as the presence of a notochord. The larval forms of Protochordates are essential … Read more
What is Theta model of DNA Replication? The theta model of DNA replication is a mechanism for DNA replication which occurs in circular DNA molecules, in particular, those of bacteria, and also the mitochondria and chloroplasts. True to its name, this replication process creates an intermediate structure during replication that resembles the Greek letter theta … Read more
What is Codon? Molecular biologists define a codon as three nucleotides of DNA or RNA. Such is said to code for some particular amino acid, but it may also work as a signal in the course of regulation during the synthesis of protein. In brief, life proceeds generation after generation due to complex steps that … Read more
What is Laboratory Incubator? An incubator serves as a temperature-controlled, insulated container that laboratories utilise for cultivating and maintaining various biological cultures. This essential piece of equipment creates optimal conditions necessary for growing microorganisms in artificial environments. Like most sophisticated lab instruments, it maintains precise control over environmental factors such as temp, moisture levels, and … Read more
What Is Bacterial Transformation? Bacterial Transformation Definition Bacterial transformation is the process by which a bacterium takes up free DNA from its environment and incorporates it into its genome, potentially expressing new traits. Principle of Bacterial Transformation Types of Bacterial Transformation Bacterial transformation can occur naturally or be induced artificially. Both forms allow bacteria to … Read more
What is Bacterial Conjugation? Bacterial Conjugation Definition Bacterial conjugation is a process of genetic exchange where DNA is transferred from a donor cell to a recipient cell through direct contact, typically mediated by a pilus. It is a key mechanism of horizontal gene transfer, often involving plasmids, and contributes to genetic diversity and the spread … Read more
What is DNA Replication? Definition of DNA Replication DNA replication is the biological process by which a cell duplicates its DNA molecule, producing two identical copies from one original DNA strand, ensuring the transmission of genetic information during cell division. DNA Replication Enzymes and Proteins DNA replication is a fundamental biological process, relying on various … Read more
What are Viruses? Origins of Viruses Viruses have likely existed since the earliest life forms and have evolved alongside cellular organisms. Due to their lack of fossil records, the origins of viruses remain unclear, and scientists use molecular biology techniques to explore their evolutionary history. Three primary hypotheses attempt to explain how viruses may have … Read more
The fungi are classified based on the characteristics of the sexual spores and fruiting bodies present during the sexual stages of their life cycles. Therefore, based on characteristics of their sexual stages and morphology of their asexual spores and thalli they are classified into different groups.
