DNA (Deoxyribonucleic Acid) sequencing is to determine the order of four chemical building blocks called “bases” that makes up DNA molecule. DNA sequence is a genetic information that is carried out in specific DNA segment. This DNA sequence information can be used to determine which stretches of DNA that contain genes and which transmit supervisory instructions, turning genes on or off and most importantly, sequence data can highlight variations in a gene that may cause disease.     In DNA sequence, double helix, the four chemical bases constantly bond with the same

There are an increasing number of applications that have been developed for oligonucleotide-based biosensing systems in genetics and biomedicine. Oligonucleotide-based biosensors are those where the probe to capture the analyte is a strand of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or a synthetic analogue of naturally occurring nucleic acids. This review will shed light on various types of nucleic acids such as DNA and RNA (particularly microRNAs), their role and their application in biosensing. It will also cover DNA/RNA aptamers, which can be used as bioreceptors for a wide range

The relationship among of sperm DNA damage in cows with pregnancy rates has not been widely studied. The purpose of this study to determine the relationship of sperm DNA damage with pregnancy rate on Brahman cows. The sperm DNA damage rate was measured by Sperm-BosHalomax® from 2 samples of male Brahman bull straw (40002 and 40885) and pregnancy rate was measured from the success rate of artificial insemination. In 14 female Brahman cows divided into two groups. One group of 7 in the artificial insemination with 40002 males with 37.11% sperm DNA damage and one in artificial insemination with 4

The interaction between anionic form of copper (II) N,N',N",N'"-tetrasulfonated phthalocyanine Cu (tspc) and to calf thymus deoxyribonucleic acid (ct-DNA) is investigated by measuring UV-vis absorption and fluorescence spectroscopy in phosphate buffer. The binding constant and stoichiometry were determined by analysis of optical absorption spectra of phthalocyanine at various ct-DNA concentrations using SQUAD software. The static mode of fluorescence quenching of phthalocyanine by calf thymus deoxyribonucleic acid indicates the formation of a ground-state complex. The formation of ground-state

This article discusses dynamics of the fractal double-chain deoxyribonucleic acid model. This structure contains two long elastic homogeneous strands that serve as two polynucleotide chains of deoxyribonucleic acid molecules, bounded by an elastic membrane indicating hydrogen bonds between the base pairs of two chains. The semi-inverse variational principle and auxiliary equation method are employed to extricate soliton solutions. The collection of retrieved exact solutions includes bright, dark, periodic, and other solitons. The constraint conditions emerge naturally which ensure the presence

DNA is our memory, the repository of information passed down to us by our ancestors. It was first discovered by a young and unknown doctor from Switzerland - Friedrich Miescher in 1869. Later, in 1953, the English physicist Francis Crick and the American biologist James Watson managed to build a structural model of DNA. So what is a deoxyribonucleic acid molecule? DNA is a macromolecule consisting of two spirally twisted chains that provide storage and transmission of hereditary information. It is this nucleic acid that can be said to define us, our past and our future.

Several representative strains of Haloarcula vallismortis, Haloarcula hispanica, and other Haloarcula species not currently accepted as valid species were examined for genetic relatedness to each other and to members of other halobacterial species. The G + C content of DNA of the 11 strains of the genus Haloarcula tested ranged between 56.9 and 66.3 mol%. The G + C contents obtained for Haloarcula vallismortis and Haloarcula hispanica were 56.9–64.3 mol%, and 58.7–66.3 mol%, respectively. The results of our DNA–DNA hybridization experiments indicate that Haloarcula vallismortis and Haloarcula

Identifikasi mikroorganisme merupakan salah satu tahapan yang penting dalam bioprospeksi. Perkembangan identifikasi mikroba diawali dengan identifikasi melalui ciri-ciri morfologi, fisiologi, dan metabolisme. Namun adanya kekurangan-kekurangan metode ini yaitu berupa ketidakakuratan dan waktu identifikasi yang lama menjadikan metode secara molekuler lebih berkembang.

Abstract This current study explored the effects of fine particulate matter (PM2.5) on deoxyribonucleic acid methylation in human bronchial epithelial cells. Human bronchial epithelial cells were exposed to PM2.5 for 24 h after which, deoxyribonucleic acid samples were extracted, and the differences between methylation sites were detected using methylation chips. Subsequent gene ontology functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed for the differential methylation sites. Functional epigenetic modules analysis of the overall differential methy
