The endochorion and exochorion of Drosophila eggs are synthesized by the ovarian follicle
cells during a brief period of about 5 hr. In this terminal phase of egg chamber development …

The buoyant density of ribosomal DNA is similar in species with or without satellite DNA, and
in all species examined was distinguishable from that of the satellite DNA. In melon tissues …

In this review a critical analysis is made of the quantitative DNA variations that take place
during plant development. These include underreplication, loss and amplification of …

The dermal system comprises the outer epidermis of the pericarp, its covering of wax and
cuticle and the collenchymatous hypodermal cells. During the first of the two post-anthesis …

Differential DNA replication is a controversal item of plant physiology and cell biology. While
some authors envisage such events as basic mechanisms of cell differentiation and …

The objectives of this study were to assess the degree of restriction fragment length
polymorphism (RFLP) in Cucumis melo and to determine interrelationships among …

1. DNA was extracted from aseptical cultures of protocorms of the orchid Cymbidium and
analysed by thermal denaturation. The denaturation profiles revealed an AT-rich fraction of …

Satellite DNA amounts were examined in adult tissues of Drosophila virilis, a species whose
DNA contains three prominent satellites. Satellite amounts in DNA from six of the seven …

A specific family of tandemly repeated DNA sequences was found to diminish in the human
genome after serial passage of three strains of diploid fibroblasts. Eco RI restriction …

The relative DNA contents of adult fat body nuclei of Locusta migratoria have been assayed
by scanning microspectrophotometry after Feulgen staining, spermatid and brain nuclei …
