Yes, if you are continuously getting backs, then you will get NFT, which means you are not eligible for any technical degree.

An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas and plasma is composed of neutral or ionized atoms. Atoms are very small, typical sizes are around 100 Picometers (A ten-billionth of a meter, in the short scale).

Avogadro's law states that, equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.
For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional, if the temperature and pressure are constant.

There is no exam to get admission for B.Sc biotech. For M.Sc, you can prefer TIFR or IIT JAM.
All the best.

RNA silencing or RNA interference refers to a family of gene silencing effects by which gene expression is negatively regulated by non-coding RNAs such as microRNAs. RNA silencing may also be defined as sequence-specific regulation of gene expression triggered by double-stranded RNA (dsRNA).
RNA silencing mechanisms are highly conserved in most eukaryotes. The most common and well-studied example is RNA interference (RNAi), in which endogenously expressed microRNA (miRNA) or exogenously derived small interfering RNA (siRNA) induces the degradation of complementary messenger RNA.
