Low molecular weight RNA in cell components of Chironomus tentans salivary glands.
TLDR
The results suggest that 4 s RNA is formed from RNA of slower migration rate in chromosomes, nuclear sap and cytoplasm, and in the nucleolus, label appears immediately in the 4 s position and the profile does not show any evidence of shifts with aging in the migration properties of the fractions.About:

Function and Structure of Polytene Chromosomes During Insect Development
TL;DR: This chapter highlights some of the more important lacunae in the knowledge of polytene chromosome puffs, their physiology and biochemistry.

Physiology of growth and development: endocrine aspects
TL;DR: This chapter reviews the influence that endocrine hormones have on the growth and development of insects and investigates the regulation and mechanism of synthesis and release of neurosecretion in insect cells.
Journal ArticleDOI
The 5 s RNA genes of Drosophila melanogaster.
TL;DR: It was concluded that few, if any, of the 5 s genes reside in the X or Y chromosomes, and therefore that most, if not all, ofThe genes for 5 s RNA are located in the autosomes.

Ribonucleic acid maturation in animal cells.
TL;DR: It is concluded that discussions can be made for and against RNA maturation processes being beneficial to higher organisms, but at the moment these are only hypothetical and no convincing evidence is available to support any one in particular.
Journal ArticleDOI
Morphology and structure of polytene chromosomes.
TL;DR: This chapter focuses on the gene mapping and building of cytogenetic maps, as well as on problems pertaining to the genetic organization of the main morphological structures of polytene chromosomes—the chromomeres and interchromomeric regions.

Journal ArticleDOI
The fractionation of high-molecular-weight ribonucleic acid by polyacrylamide-gel electrophoresis.
TL;DR: Electrophoresis in 2.2-2.6% gels gives a fractionation similar to density-gradient centrifugation, and the resolution is greater and more detailed than by centrifugations, and many samples can be analysed simultaneously and rapidly.
Journal ArticleDOI
Electrophoretic separation of viral nucleic acids on polyacrylamide gels
TL;DR: The elution of viral RNA from gel slices and the demonstration of infectivity after electrophoresis are described, showing a general relationship between the logarithm of the molecular weight and the relative electrophoretic mobility.

Small molecular weight monodisperse nuclear RNA.
TL;DR: The nuceloplasm and nucleolus of HeLa cells contain six distinct low molecular weight species of RNA that are long-lived and do not appear to be precursor to any cytoplasmic product.
