Each puff represents a discrete site of transcription. The polytene appears as a parallel line of bands. These bands are called “puffs”; Rna transcription is occurring in a puff of a polytene chromosome. 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. How do we know this experimentally? Web the euchromatic part of polytene chromosomes often show in addition to the band/interband pattern sites that appear more expanded and less dense (puffs). Web induction of puffs in polytene chromosomes of in vitro cultured salivary glands of drosophila melanogaster by ecdysone and ecdysone analogues | nature new biology. A diffuse uncoiled region in a polytene. A swelling at a site along the length of a polytene chromosome;

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. We know it by autoradiography(incorporation of radioactive ribonucleotides). Web induction of puffs in polytene chromosomes of in vitro cultured salivary glands of drosophila melanogaster by ecdysone and ecdysone analogues | nature new biology. Web chromosome puffs are diffuse swellings along the regularly banded arms of polytene chromosomes (see also lezzi, chapter 4, this volume). Web chromosomes are unit of the genomes that have genes having very long molecule of. Chromosome puff (balbiani ring) a swollen region of a polytene chromosome, corresponding to a site where messenger rna synthesis. The criteria for classifying chromosomes are according to the length,. Rna transcription is occurring in a puff of a polytene chromosome. The polytene appears as a parallel line of bands. Web the euchromatic part of polytene chromosomes often show in addition to the band/interband pattern sites that appear more expanded and less dense (puffs). Web during larval development, specific areas on polytene chromosomes become uncoiled, forming localized regions called ‘pufs’.
