Polytene chromosomes of Chironomus amissum sp. n. a. Chromosome AE. b
What Is A Puff In A Polytene Chromosome. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids.

Web chromosome puffs are diffuse swellings along the regularly banded arms of polytene chromosomes (see also lezzi, chapter 4, this volume). How do we know this experimentally? Chromosome puff (balbiani ring) a swollen region of a polytene chromosome, corresponding to a site where messenger rna synthesis. Web it is a giant chromosome that is found in the oocytes or immature egg (germ cells in the ovary) of most of the vertebrates such as fishes, amphibians, birds and reptiles, and in. The polytene appears as a parallel line of bands. Each puff represents a discrete site of transcription. Web during larval development, specific areas on polytene chromosomes become uncoiled, forming localized regions called ‘pufs’. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. We know it by autoradiography(incorporation of radioactive ribonucleotides). The site of active transcription.

The site of active transcription. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. Web what united processes occurring in a puff of polity of chromosome site of gene transcription, the puff represents a sect section of dna that has been uncoiled for transcription. Each puff represents a discrete site of transcription. A diffuse uncoiled region in a polytene. Assertion :polytene chromosomes have a high. We know it by autoradiography(incorporation of radioactive ribonucleotides). Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids. The polytene appears as a parallel line of bands.
