trxG proteins are a structurally diverse set of polypeptides that are associated with transcriptionally active chromatin and required for homeotic gene expression. Several of these proteins are related to SWI/SNF factors and function in chromatin remodelling.For example, the Drosophila BRAHMA, MOIRA, OSA, SNR1 and KISMET proteins, and their known vertebrate homologues, are components of complexes with ATP-dependent chromatin remodelling activity (Simon and Tamkun, 2002).bstract. Multicellular development is programmed by regulated interactions between transcription factors and target genes. Target genes function as nucleosomal arrays whose higher order structure, composition and accessibility to transcription machinery are strictly and dynamically controlled.

Shairi: It is also known as Rustavelian Quatrain and uses the rhyming form aaaa and is mainly used in Urdu and farsi poetry. Shichigon-zekku: This form is mainly used in Chinese and Japanese poetry. Both rhyme and rhythm are key elements, although the former is not restricted to falling at the end of the phrase.ost of the ballads and hymns are composed in quatrains where the second and fourth lines rhyme with the rhyming scheme abcb or abab. The âheroic quatrainâ of iambic pentameters also rhymes using the form abab. A different rhyme scheme (abba) is used in the In Memoriam stanza and some other forms.
