Nucleus: Organization, Division and Structure (With Diagram)

Most of the functions of the nucleus are intimately related to events that occur in the cytoplasm; for ex­ample, translation of mRNA by cytoplasmic ribosomes is the end result of the transcription of DNA in the nucleus and the processing of the resulting RNA. Structurally too, the nucleus and cytoplasm are interrelated. The outer membrane of the nuclear envelope is [...]

Important Functions of Nucleus | Biology

Some of the important functions of Nucleus are as follows: J. Hammerling in 1934 demonstrated that the nucleus controls the functions of the cells and ultimately the characters of the individuals by conducting experiments on Acetabularia, a unicellular marine alga. Acetabularia has a stem between 3 and 5 cm long and a cap 1 cm in diameter. The nucleus is [...]

Chemical Composition of Nucleus | Biology

This article provides information about the Chemical Composition of Nucleus! The nucleus contains mainly nucleoproteins composed of nucleic acid and proteins, besides enzymes and inorganic salts. The following is the percentage of different components of nucleus of mammalian liver cells in interphase, determined by spectrophotometric analysis: DNA 9% Residual protein 14% RNA 1% other acidic proteins 65% Histone protein 11% [...]
