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. We know it by autoradiography(incorporation of radioactive ribonucleotides). Web what genetic process is occurring in a puff of a polytene chromosome? A swelling at a site along the length of a polytene chromosome; Chromosome puff (balbiani ring) a swollen region of a polytene chromosome, corresponding to a site where messenger rna synthesis. How do we know this experimentally? 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 during larval development, specific areas on polytene chromosomes become uncoiled, forming localized regions called ‘pufs’. The criteria for classifying chromosomes are according to the length,.
Each puff represents a discrete site of transcription. Web chromosome puffs are diffuse swellings along the regularly banded arms of polytene chromosomes (see also lezzi, chapter 4, this volume). Web what genetic process is occurring in a puff of a polytene chromosome? Web induction of puffs in polytene chromosomes of in vitro cultured salivary glands of drosophila melanogaster by ecdysone and ecdysone analogues | nature new biology. The polytene appears as a parallel line of bands. These bands are called “puffs”; Each puff represents a discrete site of transcription. Rna transcription is occurring in a puff of a polytene chromosome. A diffuse uncoiled region in a polytene. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. Chromosome puff (balbiani ring) a swollen region of a polytene chromosome, corresponding to a site where messenger rna synthesis.
