Post-translational modifications (PTMs) of histones are crucial for protein structure regulation, playing key roles in gene expression regulation, DNA repair, cell signaling, and more. These PTMs of histones can be achieved by adding or removing different chemical groups or proteins, thus affecting chromatin structure and function. Here are some common types of histone PTMs. 1. Acetylation The ...
What is Chimeric RNA? Chimeric RNA, also known as fusion RNA, refers to RNA molecules that are formed as a result of the fusion of two or more different RNA transcripts. Chimeric RNA, a unique class of RNA molecules formed through various molecular mechanisms, such as trans-splicing, read-through transcription, and fusion genes. These hybrid transcripts play a significant role in diverse ...
Protein-DNA docking is a complex and critical technique used in the field of structural biology. It involves the study of the three-dimensional structure of biological macromolecules, which play vital roles in many biological processes such as transcription, replication, and DNA repair. Protein-DNA docking allows researchers to predict how proteins and DNA interact with each other, providing ...
Bioinformatics is a discipline developed on the basis of biology, mathematics and computer science. It effectively acquires and analyzes biological data such as nucleic acid sequences and protein structures, so as to conduct comprehensive and accurate biological analysis. Bioinformatics is an extremely important tool to study the microorganisms, which are widespread and highly varied. ...
Epigenetics is an emerging field of research that focuses on the effects of environmental factors, such as infections, pollutants, stress, and long-term drug exposure, on an individual's genome. Epigenetic changes do not alter the structure of DNA, but do alter the way DNA is modified. Thereby, those changes include DNA methylation, histone modifications and non-coding RNAs. affects gene ...
Unlike prokaryotic cells, eukaryotic cells can regulate gene expression at many different levels. Epigenomic changes are inheritable changes in gene expression and are not caused by changes in DNA sequences. In microbial epigenomics studies, molecular processes influencing epigenomic inheritance have been discovered from microbial eukaryotes such as Neurospora crassa and Schizosaccharomyces ...
The purpose of the present paper is an attempt to determine the molecular differences and fingerprinting of a normal and genetically engineered Saccharomyces cerevisiae human insulin producer obtained through transformation with human DNA (introns and exons) isolated from healthy human pancreas. Five primers were used; four with 20-mer and one with 10-mer. Gels photographs for all primers using ...
