Polytene chromosomes of Glyptotendipes glaucus Mg. from Kaliningrad
Chromosome puff (balbiani ring) a swollen region of a polytene chromosome, corresponding to a site where messenger rna synthesis. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. How do we know this experimentally? The site of active transcription. Puffs represent regions of active rna synthesis. Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids. Web during larval development, specific areas on polytene chromosomes become uncoiled, forming localized regions called ‘pufs’. 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. The criteria for classifying chromosomes are according to the length,. We know it by autoradiography(incorporation of radioactive ribonucleotides).
A swelling at a site along the length 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 chromosomes are unit of the genomes that have genes having very long molecule of. The criteria for classifying chromosomes are according to the length,. Web what genetic process is occurring in a puff of a polytene chromosome? Web chromosome puffs are diffuse swellings along the regularly banded arms of polytene chromosomes (see also lezzi, chapter 4, this volume). Each puff represents a discrete site of transcription. Rna transcription is occurring in a puff of a polytene chromosome. Assertion :polytene chromosomes have a high. 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. Polytene chromosomes are formed by repeated replication of chromosomal dna without separation of chromatids.
