Other claims from this paper (8)
- Observation Plant nuclear reticulum and chromosomes reacted for thymusnucleic acid, lipoids and proteins.
- Observation Plant chromosomes dissolved more readily in lipoid and nucleoprotein solvents than resting nuclei.
- Observation The chromosome spiral portion was more resistant to lipoid solvents than the matrix.
- Observation The authors found suggestive evidence of material changes in nuclear components during mitosis.
- Observation Spirogyra nuclei lacked a thymusnucleic acid reaction but showed a protein reaction.
- Observation Karyolymph tested negative for thymusnucleic acid, lipoids and proteins, although precipitation suggested possible lipoid.
- Observation The nucleolus contained lipoids but no thymusnucleic acid.
- Observation Spindle fibers and phragmoplast consisted mainly of proteins and lipoids in mixed or combined form.
