Example sentences for: polytene

How can you use “polytene” in a sentence? Here are some example sentences to help you improve your vocabulary:

Rather, it is possible that this phenomenon indicates allelic-interactions, particularly given that the alleles are closely associated in a polytene chromosome at the time they are processed (homologs are paired in the polytene anlage of Stichotrichs [ 60 61 ] ). For instance, transvection is a phenomenon dependent on homolog pairing; transvection normally is evidenced by rescued gene expression in heterozygotes of two alleles defective in different cis -acting sequence features, which interact (in trans ) to essentially complement one another (review: [ 62 ] ).
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].
Polytene chromosomes, which are so valuable in mapping euchromatic genes in Drosophila , provide minimal resolution in the heterochromatin.
The boundary of the centric heterochromatin of the X chromosome at the distal edge of band h26 corresponds approximately to polytene division 20C, band h35 on chromosome arm 2L corresponds to polytene division 40A, band h45 on 2R corresponds to polytene division 41F, band h47 on 3L corresponds to polytene division 80A, and band h58 on 3R corresponds to polytene division 82C.
We determined the number of polytene bands present in each group of similarly expressed genes.
