In the realm of epigenetics, histone modification constitutes a crucial research area. It involves a series of chemical alterations to histones subsequent to translation. These modifications do not modify the DNA sequence but exert a substantial impact on gene expression and chromatin structure. Introduction of Histone Modification Histone modification refers to the chemical modification of […]
Epigenetic modification represents a sophisticated regulatory mechanism in biology. It involves the modulation of gene expression through chemical alterations or changes in chromatin structure, all while leaving the underlying DNA sequence intact. This mode of regulation has far – reaching implications for a wide range of biological processes, from cellular differentiation during development to the […]
Chromatin remodeling refers to the process of changing the chromatin structure by regulating factors such as transcription factors, histone modifying enzymes and ATP-dependent remodeling complexes. This process includes changing nucleosome density, nucleosome assembly mode, and even adjusting the structure of the whole chromatin region, which directly affects chromatin accessibility and gene expression. What is Chromatin […]
Introduction Within cellular biology, chromosomes and chromatin function as essential vehicles for genetic material, fulfilling crucial functions during various phases of cellular existence. Chromatin represents the intricate association of DNA with proteins residing in the nuclear compartment, while chromosomes emerge as highly condensed formations when cells undergo division. These structures collaborate to maintain genomic integrity […]
What are Gene Fragments? Gene fragments refer to DNA segments synthesized through biochemical methods, typically comprising linear double-stranded DNA varying in length from several hundred to several thousand base pairs. These segments may contain exonic regions of genes or specific areas of the gene sequence. For instance, a cloned gene denotes a particular gene sequence […]
Gene fragment analysis is a transformative genetic analysis method that enables researchers to glean information on gene size, relative quantification, and genotyping through the separation and detection of fluorescently labeled DNA fragments. Its widespread adoption within the research community is attributed to its high sensitivity, resolution, and rapid turnaround. This technique plays an instrumental role […]
Plastid genomic landscapes reveal critical insights into plant molecular biology. Researchers investigate the gene repertoire within these genomic structures, exploring their composition, structural variability, and evolutionary implications across diverse botanical species. But how many genes are typically found in the plant plastid genome? This article dives into the fascinating details of plastid genome structure, gene […]
Introduction to Adeno-Associated Virus (AAV) 1. Overview and Basic Structure Originally identified during the 1960s, the adeno-associated virus represents a significant advancement in genetic research and therapeutic applications. This small, non-enveloped virus belongs to the Parvoviridae family’s Dependoparvovirus genus. Its genetic material consists of single-stranded DNA spanning approximately 4.7 kb. Research indicates widespread human exposure, […]
What is Lentiviral Transduction Lentiviral transduction is a method employed to introduce a target gene into recipient cells via lentiviral vectors, facilitating its stable expression. When compared to other viral vectors, lentiviral vectors offer distinct advantages, particularly in integrating genes into non-dividing cells. Typically derived from a modified version of the human immunodeficiency virus (HIV), […]
Introduction: What is KEGG and Why is it Important for Researchers The Kyoto Encyclopedia of Genes and Genomes (KEGG) is an advanced computational tool in molecular biology research. Originated by Kanehisa Laboratories during 1995, this innovative database emerged as a comprehensive genomic repository, dedicated to advancing deep understanding of complex biological systems. Through continuous evolution, […]
