How can you use “polytene” in a sentence? Here are some example sentences to help you improve your vocabulary:
We determined the number of polytene bands present in each group of similarly expressed genes.
The second use of polytene chromosomes in evolutionary studies is as tracers of phylogeny [ 3 4 5 6 7 ] . This approach has resulted in important and detailed chromosomal phylogenies for several groups of flies in the genus Drosophila . Lists of species for which polytene chromosome maps have been produced are available [ 8 9 ] , and over 300 species of Drosophila have been examined at this level.
The BACs that we localized on the cytological map of the mitotic chromosomes have also been positioned using in situ hybridization to salivary gland polytene chromosomes [ 47, 60].
Some insulator-binding proteins localize to a few hundred chromosomal positions, and these positions coincide with genomic sequences that are not heavily compacted by chromatin structure (the 'interbands' of polytene chromosomes) [ 3].
Although banding in the proximal regions of the polytene chromosomes is not as distinct as in the euchromatic regions, comparison of the two datasets shows the approximate extent of overlap between the mitotic and polytene cytogenetic maps (Table 1).
