متن کاملDna in Gametogenesis and Embryogeny in Tradescantia
A microphotometric study of various Feulgen-stained gametophytic and sporophytic nuclei of Tradescantia paludosa was made to test the hypothesis that DNA is maintained in multiples of a basic unit within all cells of an organism. A multiple relationship was found in all tissues analyzed. The lowest amount of DNA was found in gametophytic nuclei, approximately twice and four times this amount in...
متن کاملChromosome Behavior and Nuclear Development in Tradescantia.
