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.
ASBA means âApplications Supported by Blocked Amountâ. ASBA is an application containing an authorization to block the application money in the bank account, for subscribing to an issue.n ASBA, an IPO applicant's account doesn't get debited until shares are allotted to them. Earlier Qualified Institutional Buyers (QIBs) were not allowed to participate in IPOs through ASBA facility.
4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the number 4 carbon in the benzene ring is also known as the para position) is an organic compound with the formula H 2 NC 6 H 4 CO 2 H. PABA, a white-grey crystalline substance, is only slightly soluble in water.n the past, PABA was widely used in sunscreens as a UV filter. It is a UVB absorber, meaning it can absorb wavelengths between 290 and 320 nm. Patented in 1943, PABA was one of the first active ingredients to be used in sunscreen. The first in vivo studies on mice showed that PABA reduced UV damage.
