Brucella is a genus of small Gram-negative coccobacilli. It is non-motile and non-spore forming, and it is the organism responsible for a zoonotic disease called brucellosis. It is the process where the bacteria survive as facultative intracellular parasite inside different host cells. These organisms are named after David Bruce and are placed under the family … Read more
Okazaki fragment is the short segment of DNA that is synthesized on the lagging strand during DNA replication. It is formed because the DNA polymerase can extend the new strand only in the 5’–3’ direction, so the strand that is oriented in the 3’–5’ direction is produced in a discontinuous manner. It is initiated by … Read more
A dihybrid crossing is a gene-cross between people who have homozygous or heterozygous genotypes that have two distinct characteristics or traits. Dihybrid crosses differ from the monohybrid crossing that only involves one genetic character or characteristic.

Pureline selection is a method used in plant breeding where plants are chosen from a single self-pollinated variety to create a population that is genetically uniform. It was first introduced by Johannsen (1903) while working with beans (Phaseolus vulgaris). The method based on assumption that variation seen in self-pollinated crops is mostly due to environment … Read more
Post-transcriptional modification is a set of biological processes common to most eukaryotic cells by which an primary RNA transcript is chemically altered following transcription from a gene to produce a mature, functional RNA molecule that can then leave the nucleus and perform any of a variety of different functions in the cell.
What is Analytical balance? What is Triple beam balance? Difference Between Analytical Balance Vs Triple Beam Balance 1. Precision – Analytical balance gives very high precision (up to 0.0001 g) while triple beam balance only measure till 0.01 g, so less sensitive comparatively. 2. Power Source – Analytical balance mostly works on electric / electronic … Read more
