Changes in ribonucleic acid fractions during maturation of mimosa epicotyl tissues.
Total RNA and DNA of mimosa epicotyl tissues were extracted and the RNA fractionated into specific soluble RNAs (sRNAs) at different times during late germination. Epicotyls collected at each time contained qualitatively comparable meristematic and developing tissues, while mature tissues increased. Quantitative ratios of total RNA to DNA and total sRNAs to approximated ribosomal RNA (rRNA) var...
متن کاملTemperature Controlled Growth Rates and Ribonucleic Acid Characteristics in Mimosa. Epicotyl Tissue.
Clhaniges in RNA metabolismii during nornmal growth have been reported (2. 6, 9,11, 15). Since RNA plays a vital role in enzyme synthesis, varying enivironmental conditions and growth rates should be reflected in the RNA metabolism through these enzyme systems. Environmental effects. which are correlated with growth rate (8), have been shown to affect solmie RNA characteristics (5, 13, 18, 19)....
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Studies in rapidly labelled ribonucleic acid in cell fractions and in tumour tissues.
1. Twenty minutes after injection of [(3)H]orotic acid into rats the rapidly labelled RNA from the liver is mainly associated with the nuclear fraction and little with the ribosomal cytoplasmic fraction. 2. The thermal denaturation of RNA from the fractions was not as reversible as that of the RNA extracted from whole liver. 3. Rapidly labelled RNA is synthesized by cells from a transplantable ...
متن کاملEvaluation of Changes in Fatty Acid Composition in Three Different Varieties of Olives During the Course of Maturation
ABSTRACT: Olives belong to the family of olea europaea L. is a popular fruit tree. The fruit and the oil extracted from it is consumed worldwide particularly in the Mediterranean regions. In this study changes in the fatty acid composition of the oil extracted from olive fruit during the course of maturation is investigated. This work is concerned with the best harvesting point when oleic acid ...
