Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
Why does nucleation rate cause the number of microtubules to be proportional to nucleation rate but the length of microtubules to be inversely proportional to nucleation rate?
Microtubules are key elements in maintaining structural integrity, cell signalling, transport and cell divisions of the cell. Microtubulin grow or shrink in size by adding or removing tubulin proteins.
Microtubules exhibit dynamic instability in the form of slow growth followed faster shortening
Microtubule nucleation starts the in vitro microtubule formation. The growth of microtubules takes place by addition of GTP-bound αβ-tubulin heterodimers to their ends.
The pure GTP tubulin plays an important role in the assembly of the microtubules in the cell. This depends on exchange between soluble and polymeric tubulin pools.
