Cloning regions of the Drosophila genome by microdissection of polytene chromosome DNA and PCR with nonspecific primer.
A simple and rapid procedure to isolate clones carrying sequences from a specific region of the polytene chromosome of Drosophila is demonstrated. The procedure involves microdissection of the region of interest, amplification of the DNA by PCR using a primer designed to prime the synthesis nonspecifically, labeling of the amplified DNA using the random primer method, and screening of a standar...
متن کاملMicrodissection of Drosophila polytene chromosomes for DOP-PCR.
This protocol describes a method for the microdissection of Drosophila polytene chromosomes. The microdissected DNA can be amplified by degenerate oligonucleotide primed-polymerase chain reaction (DOP-PCR) and then used to prepare probes for fluorescent in situ hybridization (FISH).
متن کاملUltrastructure of polytene chromosomes of Drosophila isolated by microdissection.
Drosophila polytene chromosomes prepared by a new micromanipulative procedure, which avoids acid squashing, have been examined at the ultrastructural level in the electron microscope. Puffs at 2B, 68C, 74EF, 75B and 85EF, have been examined in some detail, along with the chromocentre and various interbands. The ultrastructure of these chromosomes, which have never been exposed to acid protein d...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولA Nonspecific Primer Anchored PCR Technique for Chromosome Walking
A chromosome walking method was improved in this work. The new method was named as nonspecific primer anchored PCR (NPA-PCR). Nested gene specific primers were designed based on the known region and long random primer using degeneracy oligonucleotides for nonspecific anchoring. Annealing temperatures were varied to control the priming. Target sequences were obtained by PCR with random primer an...
