			Protein Analysis Using Small-Angle X-Ray Scattering (SAXS) Small-angle X-ray scattering (SAXS) is an analytical technique used to identify differences in density within a sample with nanoscale resolution. It works by analyzing the elastic scattering angles of X-rays. SAXS can determine the nanoscale structure of solids, liquids and gaseous particulate matter of almost any material, including biomacromolecules, such as proteins and nucleic acids.

			GC-MS/MS of dried urine is a ‘good surrogate’ for serum testing of hormones Researchers have shown that analyzing dried urine extracts with GC-MS/MS to assess levels of reproductive hormones in pre-and post-menopausal women provides similar results to radioimmunoassays using serum samples.

	Using Mass Spectrometry for Protein Complex Analysis Mass spectrometry (MS) is considered to be a powerful method for quickly and efficiently identifying protein samples. Most crucial issues in the analysis of protein complex through MS include specificity of protein complex and contaminants in background protein.

	Scientists decipher transcriptome of drumstick tree by RNA sequencing Did you ever wonder why our grandmothers insisted on having a Tulsi plant in front of the house and a Moringa tree in the backyard? Each and every part of the drumstick tree has medicinal value and is a rich source of nutrients and minerals.

	DNA Repair and Transcription: A Balancing Act Transcription is the process by which DNA is converted into messenger RNA in preparation for translation into a functional product. Extrinsic agents, such as ionizing radiation or chemical mutagen and intrinsic processes, for example, replication fork collapse, may result in cellular double-stranded breaks (DSBs) leading to global genomic instability.

	Neuronal transport factor detects its target transcripts in more complex manner than previously thought A team of scientists from Helmholtz Zentrum München and the University of Ulm has discovered that the neuronal transport factor Staufen2 scans and binds to its target transcripts in a much more complex manner than previously thought. RNA is transported within highly complex protein-RNA particles whose structure and specificity are still poorly understood.

	Mitochondrial DNA Organization and Replication Steps This article describes the organization of mitochondrial DNA into nucleoids and the replication process, including initiation, elongation, termination and the involvement of polymerase enzymes.
