Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...
The rented premises of the school and its plans for a school building were inspected in November 1992 and the school was granted composite affiliation until Grade X for 1993 (see CBSE letter reference number CBSE/Aff/91/61304, dated 22-12-1992). The first batch of Class X students appeared at the AISS Examination of the CBSE in March
The examination consisted of one paper containing 180 objective type questions from Physics, Chemistry and Biology (Botany & Zoology), having 45 questions from each subject. The exam duration was 3 hours. Each question carried 4 marks. For each incorrect response, one mark used to be deducted from the total score.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Virulence plasmids contain the genetic elements necessary for bacteria to become pathogenic. Degradative plasmids that contain genes that allow bacteria to degrade a variety of substances such as aromatic compounds and xenobiotics. [12] Bacterial plasmids can also function in pigment production, nitrogen fixation and the resistance to heavy ...

Chromosome 12 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 12 spans about 133 million base pairs (the building material of DNA ) and represents between 4 and 4.5 percent of the total DNA in cells .
Extracellular RNA (exRNA) describes RNA species present outside of the cells in which they were transcribed. Carried within extracellular vesicles, lipoproteins, and protein complexes, exRNAs are protected from ubiquitous RNA-degrading enzymes. exRNAs may be found in the environment or, in multicellular organisms, within the tissues or biological fluids such as venous blood, saliva, breast ...
