The site of active transcription. Web chromosomes are unit of the genomes that have genes having very long molecule of. Puffs represent regions of active rna synthesis. Web during larval development, specific areas on polytene chromosomes become uncoiled, forming localized regions called ‘pufs’. Rna transcription is occurring in a puff of a polytene chromosome. 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). 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. How do we know this experimentally? Assertion :polytene chromosomes have a high.
Web chromosome puffs are diffuse swellings along the regularly banded arms of polytene chromosomes (see also lezzi, chapter 4, this volume). The polytene appears as a parallel line of bands. How do we know this experimentally? Puffs represent regions of active rna synthesis. Each puff represents a discrete site of transcription. 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. Web what genetic process is occurring in a puff of a polytene chromosome? The site of active transcription. Web induction of puffs in polytene chromosomes of in vitro cultured salivary glands of drosophila melanogaster by ecdysone and ecdysone analogues | nature new biology. Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids. 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.
