What is cleavage? Characteristics of cleavage Step by step process of Cleavage Types of cleavages The cleavage pattern in embryos mainly determined by yolk quantity and how that yolk is distributed by the cytoplasm.Also, timing and direction of mitotic spindle (inside egg) play important role. Yolk usually slow / restrict the process of complete division. … Read more
What are plasmids? Copy Number and Physical Nature of Plasmids Properties of Plasmids Plasmid Replication Mechanism 1. Rolling circle Mode of Replication Rolling-Circle Replication (RCR) is described as a method of DNA replication that is used by some viruses, plasmids and circular genetic elements. A single-strand nick is introduced at the origin and the 5′-end … Read more
Microorganisms are everywhere in their the distribution. In any given environment, many microorganisms are present at any given time. It is difficult to identify a specific kind of microbe until we understand their ecological needs. For instance, anaerobic microbes do not require oxygen those that are aerobic require oxygen micro-aerophiles to have oxygen however, in a small amount. So, we require cotton plugs to provide an conditions that are aerobic and keep the growing culture uninvolved with unwanted microbes. Cotton plugs are made of cotton along with air pours. Air can flow through air pours, but not the bacteria that cause microbial contamination. They are fixed to the surface of cotton fibres , and prevent them from being able from getting into flasks, tubes, etc. Air aids in for the development of microorganisms within glass equipment.
What is Laboratory Incubator? A Laboratory Incubator is described as a device that is used to grow and maintain microbial / cell cultures under controlled temperature, humidity, and gas conditions. The environment inside is usually kept stable, and temperature is controlled (often by thermostats/sensors), though fluctuations are caused by door openings. For mammalian cells, a … 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

Aspergillus fumigatus is classified … 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
A Desert Ecosystem is a system in which living things (plants, animals, microbes) interact with non-living parts (soil, air, water, temperature) in a region that is extremely dry. It is defined by very low rainfall (often less than about 250 mm per year), and scarcity of moisture is a crucial limiting factor. The system is … Read more
