The results of the measurements show that the mean DNA content per nucleus in the intact rat liver is 6.5 pg, and that most nuclei are about equal in size to the diploid nucleus (42.5 μ 2 ). DNA synthesis began in the regenerating liver before 18 h after the operation. By 24 h the...
Cell NucleusHumansTritiumDNAThymidinePhotometryCulture TechniquesAutoradiographyRelative nuclear DNA content and nuclear area were determined in fast growing, karyotypically normal, fibroblastic cell cultures derived from five human females. In two cultures H3 thymidine autoradiographic and photometric ...
For well over 100 years, cell biologists have been wondering what determines the size of cells. In modern times, we know all of the molecules that control the cell cycle and cell division, but we still do not understand how cell size is determined. To check whether modern cell biology has...
Nucleus sizePloidyIn order to better understand which are the factors involved in the control of nuclear size, and more precisely, to clarify why nuclear hypertrophy doesnt always follow genome increase, biological techniques combined with a strict mathematical approach have been applied to study the ...

Not all cells have a membrane-bound nucleus. Eukaryotic cells (includingplant cellsandanimal cells) have nuclei and membrane-bound organelles, whileprokaryotic cells(i.e. bacteria) do not. Nuclei contain information needed for protein synthesis and so control the activities of the whole cell. ...
What is a genome in the perspective of genetics? How many DNA molecules are present in a human cell's nucleus? How many genomes are there in the United States of America? What length or height of human DNA during the cell division?
