      Behind the headlines on cloning--Dr. Robin Cook blends fact with fiction in one of his most terrifying bestsellers Chromosome 6 is a prophetic thriller that challenges the medical ethics of genetic manipulation and cloning in the jungles of equatorial Africa, where one mistake could bridge the gap between man and ape--and forever change the genetic map of our/5. Ultrastructure of giant polytene (poly=many, tene=strands) chromosomes: It was first investigated by Beermann and Bahr (), who observed numerous fine fibrils in the Balbiani rings of Chironomus and estimated that each chromosome contains to separate strands (corresponding to the degree of .

    Background. Drosophila melanogaster was first recognized as a valuable experimental organism years ago. One of the particularly attractive features of this model system for studies of genes and their regulation is the “giant” or polytene chromosomes that occur in the secretory glands of Drosophila (as well as other dipteran flies). Historically, polytene chromosomes provided an Cited by: The Australian jack jumper ant (Myrmecia pilosula) has only a single pair of chromosomes (with the males having just one chromosome as they are haploid), the lowest number known for any animal, making it an interesting subject for studies in the genetics and developmental biology of social : Insecta.

      In his studies on the giant salivary gland chromosomes in Sciara Dr. C. W. Metz has turned his attention to the phenomenon of "puffing" and the structure of such regions. Instead of the characteristic banded structure the chromosome may vary in certain particular regions by becoming greatly expanded or "puffed.". Insect chromosomes come in two basic kinds: polytene and nonpolytene, the former of which have been especially useful in cytogenetic research. Polytene chromosomes are giant structures that contain upwards of copies of the genome (10 doublings from the initial diploid state).

Abstract. Acetic orcein staining of polytene chromosomes was introduced in shortly after the initial studies on aceto-carmine-stained chromosomes by Bridges and has remained a standard method of dye can be purchased in both its natural form as extracted from two species of lichens, Rocella tinctoria and Lecanora parella, and a synthetic by: 4.

A chromosome is a DNA (deoxyribonucleic acid) molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.

This three-dimensional genome structure plays a significant role in. giant chromosome: a stage of chromosome division that forms the giant chromosome found in the salivary gland of dipterous insects; the great width is the result of repeated divisions of the chromonema without subsequent lengthwise separation of the filaments.

Synonym(s): giant chromosome (1). Author(s): Ashburner,M; Beermann,W Title(s): Developmental studies on giant chromosomes, edited by W. Beermann, with contributions of M. Ashburner [et al.]. The recent advances in developmental biology described in Chapter 6 have established the central importance of a small number of highly conserved signal transduction pathways that mediate cell interactions crucial for animal physiology, reproduction, and development.

It seems likely that many developmental toxicants might affect development by acting on those pathways. Purchase The Role of Chromosomes in Development - 1st Edition.
