The polytene appears as a parallel line of bands. Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids. Rna transcription 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. Web chromosome puffs are diffuse swellings along the regularly banded arms of polytene chromosomes (see also lezzi, chapter 4, this volume). Chromosome puff (balbiani ring) a swollen region of a polytene chromosome, corresponding to a site where messenger rna synthesis. These bands are called “puffs”; How do we know this experimentally? The criteria for classifying chromosomes are according to the length,. The site of active 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. A diffuse uncoiled region in a polytene. Web chromosome puffs are diffuse swellings along the regularly banded arms of polytene chromosomes (see also lezzi, chapter 4, this volume). Rna transcription is occurring in a puff of a polytene chromosome. Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids. Chromosome puff (balbiani ring) a swollen region of a polytene chromosome, corresponding to a site where messenger rna synthesis. Web during larval development, specific areas on polytene chromosomes become uncoiled, forming localized regions called ‘pufs’. 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). Each puff represents a discrete site of transcription. Web what genetic process is occurring in a puff 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.
