What Is A Puff In A Polytene Chromosome. Rna transcription is occurring in a puff of a polytene chromosome. Assertion :polytene chromosomes have a high.
Polytene chromosome
We know it by autoradiography(incorporation of radioactive ribonucleotides). These bands are called “puffs”; 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. How do we know this experimentally? The polytene appears as a parallel line of bands. Each puff represents a discrete site of transcription. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. A diffuse uncoiled region in a polytene. 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 polytene appears as a parallel line of bands. A swelling at a site along the length of a polytene chromosome; The criteria for classifying chromosomes are according to the length,. A diffuse uncoiled region in a polytene. 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. A localised separation of polytene chromosomes (e.g., chromosomes of drosophila melanogaster) that represents a site of active rna. 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.
