The DNA is about 1.74 meters if stretched to its full length. To get DNA into the nucleus, it must have a compact form. The structural flexibility of the DNA allows it to form a compacted structure. Eukaryotes contain about […]
In a cell, electron flow in the ETC is done in a proper sequence from either NADH or FAD to oxygen to form ATP. The 3 complexes of ETC are associated with generation of ATP. All these complexes do not […]
DNA serves as a genetic material for both prokaryotic and eukaryotic cells. In eukaryotes, the DNA is present in the nucleus while in prokaryotic cells, it is present with all other cellular contents. In eukaryotic cells, the DNA is bound […]
RNA is similar to DNA. It is a long unbranched macromolecule which consists of nucleotides joined by phosphodiester bonds. The four bases of RNA include: Purine base: adenine and guanine Pyrimidine base: cytosine and uracil Types of RNA:- cell contains […]
Beside being the structural component of the nucleic acids, several nucleotides participate in various biochemical and physiological functions. Such nucleotides are known as biologically important nucleotides. Adenosine tri-phosphate (ATP) It serves as main source of energy for various metabolic pathways […]
