Sister to Sister: Becoming Literate in Relation

Trying to Avoid Your Sister

Connections between chromosomes are essential for their accurate segregation during cell division. In somatic cells dividing by mitosis, newly replicated sister chromatids are connected by cohesin proteins. When the sister chromatids become attached to microtubules emanating from opposite poles of the spindle, cohesins resist the pulling forces and the ensuing tension stabilizes the chromatid–m...

“Sister” miRNAs in cancers

www.landesbioscience.com Cell Cycle 3703 microRNAs (miRNAs) are short noncoding RNAs of ~22 nucleotides that negatively regulate gene expression at the post-transcriptional level. In general, miRNAs bind to the 3′ untranslated region (UTR) of its target mRNA via sequenceguided specific recognition to trigger mRNA degradation or translational repression. The biogenesis of a miRNA enables transcr...

Sister-sister incest: data from an anonymous computerized survey.

Retrospective data were entered anonymously by 1,521 adult women using a computer-assisted self-interview. Thirty-one participants were victims of sister-sister incest, 40 were victims of brother-sister incest, 19 were victims of father-daughter incest, 8 were victims of sexual abuse by an adult female (including one mother), and 232 were victims of sexual abuse by an adult male other than thei...

Sister chromatid exchange analysis in some Holstein bulls

Chromosomal appearance of 12 Holstein bulls selected for artificial inseminations were examined bysister chromatid exchanges (SCEs). For differential staining of sister chromatids bromodeoxyuridine (BrdU)was inoculated in lymphocyte cultures. The mean, maximum and minimum number of SCE per cell weredetermined 6.8 ± 1.14, 8.3 ± 1.1 and 5.7 ± 1.5, respectively. SCE frequencies of all animals were...
