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. A diffuse uncoiled region in a polytene. Each puff represents a discrete site of transcription. These bands are called “puffs”; The criteria for classifying chromosomes are according to the length,. Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids. 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). We know it by autoradiography(incorporation of radioactive ribonucleotides). 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. 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 induction of puffs in polytene chromosomes of in vitro cultured salivary glands of drosophila melanogaster by ecdysone and ecdysone analogues | nature new biology. A swelling at a site along the length of a polytene chromosome; 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). The polytene appears as a parallel line of bands. The criteria for classifying chromosomes are according to the length,. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. The site of active transcription. A diffuse uncoiled region in a polytene. These bands are called “puffs”;
